AWS App Runner will no longer be open to new customers starting April 30, 2026. If you would like to use App Runner, sign up prior to that date. Existing customers can continue to use the service as normal. For more information, see [AWS App Runner availability change](https://docs.aws.amazon.com/apprunner/latest/dg/apprunner-availability-change.html). # Security in App Runner Cloud security at AWS is the highest priority. As an AWS customer, you benefit from data centers and network architectures that are built to meet the requirements of the most security-sensitive organizations. Security is a shared responsibility between AWS and you. The [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) describes this as security *of* the cloud and security *in* the cloud: + **Security of the cloud** – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/). To learn about the compliance programs that apply to AWS App Runner, see [AWS Services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/). + **Security in the cloud** – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your company’s requirements, and applicable laws and regulations. This documentation helps you understand how to apply the shared responsibility model when using App Runner. The following topics show you how to configure App Runner to meet your security and compliance objectives. You also learn how to use other AWS services that help you to monitor and secure your App Runner resources. **Topics** + [Data protection in App Runner](security-data-protection.md) + [Identity and access management for App Runner](security-iam.md) + [Logging and monitoring in App Runner](security-monitoring.md) + [Compliance validation for App Runner](security-compliance.md) + [Resilience in App Runner](security-resilience.md) + [Infrastructure security in AWS App Runner](security-infrastructure.md) + [Using App Runner with VPC endpoints](security-vpce.md) + [Configuration and vulnerability analysis in App Runner](security-shared-responsibility.md) + [Security best practices for App Runner](security-best-practices.md) # Data protection in App Runner The AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) applies to data protection in AWS App Runner. As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks for the AWS services that you use. For more information about data privacy, see the [Data Privacy FAQ](https://aws.amazon.com/compliance/data-privacy-faq/). For information about data protection in Europe, see the [AWS Shared Responsibility Model and GDPR](https://aws.amazon.com/blogs/security/the-aws-shared-responsibility-model-and-gdpr/) blog post on the *AWS Security Blog*. For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways: + Use multi-factor authentication (MFA) with each account. + Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3. + Set up API and user activity logging with AWS CloudTrail. For information about using CloudTrail trails to capture AWS activities, see [Working with CloudTrail trails](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-trails.html) in the *AWS CloudTrail User Guide*. + Use AWS encryption solutions, along with all default security controls within AWS services. + Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3. + If you require FIPS 140-3 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see [Federal Information Processing Standard (FIPS) 140-3](https://aws.amazon.com/compliance/fips/). We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a **Name** field. This includes when you work with App Runner or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server. For other App Runner security topics, see [Security in App Runner](security.md). **Topics** + [Protecting data using encryption](security-data-protection-encryption.md) + [Internetwork traffic privacy](security-data-protection-internetwork.md) # Protecting data using encryption AWS App Runner reads your application source (source image or source code) from a repository that you specify and stores it for deployment to your service. For more information, see [App Runner architecture and concepts](architecture.md). Data protection refers to protecting data while *in transit* (as it travels to and from App Runner) and *at rest* (while it is stored in AWS data centers). For more information about data protection, see [Data protection in App Runner](security-data-protection.md). For other App Runner security topics, see [Security in App Runner](security.md). ## Encryption in transit You can achieve data protection in transit in two ways: encrypt the connection using Transport Layer Security (TLS), or use client-side encryption (where the object is encrypted before it is sent). Both methods are valid for protecting your application data. To secure the connection, encrypt it using TLS whenever your application, its developers and administrators, and its end users send or receive any objects. App Runner sets up your application to receive traffic over TLS. Client-side encryption isn't a valid method for protecting the source image or code that you provide to App Runner for deployment. App Runner needs access to your application source, so it can't be encrypted. Therefore, be sure to secure the connection between your development or deployment environment and App Runner. ## Encryption at rest and key management To protect your application's data at rest, App Runner encrypts all stored copies of your application source image or source bundle. When you create an App Runner service, you can provide an AWS KMS key. If you provide one, App Runner uses your provided key to encrypt your source. If you don't provide one, App Runner uses an AWS managed key instead. For details about App Runner service creation parameters, see [CreateService](https://docs.aws.amazon.com/apprunner/latest/api/API_CreateService.html). For information about AWS Key Management Service (AWS KMS), see the [AWS Key Management Service Developer Guide](https://docs.aws.amazon.com/kms/latest/developerguide/). # Internetwork traffic privacy App Runner uses Amazon Virtual Private Cloud (Amazon VPC) to create boundaries between resources in your App Runner application and control traffic between them, your on-premises network, and the internet. For more information about Amazon VPC security, see [Internetwork traffic privacy in Amazon VPC](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Security.html) in the *Amazon VPC User Guide*. For information about associating your App Runner application with a custom Amazon VPC, see [Enabling VPC access for outgoing traffic](network-vpc.md). For information about securing requests to App Runner using a VPC endpoint, see [Using App Runner with VPC endpoints](security-vpce.md). For more information about data protection, see [Data protection in App Runner](security-data-protection.md). For other App Runner security topics, see [Security in App Runner](security.md). # Identity and access management for App Runner AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be *authenticated* (signed in) and *authorized* (have permissions) to use App Runner resources. IAM is an AWS service that you can use with no additional charge. For other App Runner security topics, see [Security in App Runner](security.md). **Topics** + [Audience](#security-iam.audience) + [Authenticating with identities](#security-iam.authentication) + [Managing access using policies](#security-iam.access-manage) + [How App Runner works with IAM](security_iam_service-with-iam.md) + [App Runner identity-based policy examples](security_iam_id-based-policy-examples.md) + [Using service-linked roles for App Runner](security-iam-slr.md) + [AWS managed policies for AWS App Runner](security-iam-awsmanpol.md) + [Troubleshooting App Runner identity and access](security_iam_troubleshoot.md) ## Audience How you use AWS Identity and Access Management (IAM) differs based on your role: + **Service user** - request permissions from your administrator if you cannot access features (see [Troubleshooting App Runner identity and access](security_iam_troubleshoot.md)) + **Service administrator** - determine user access and submit permission requests (see [How App Runner works with IAM](security_iam_service-with-iam.md)) + **IAM administrator** - write policies to manage access (see [App Runner identity-based policy examples](security_iam_id-based-policy-examples.md)) ## Authenticating with identities Authentication is how you sign in to AWS using your identity credentials. You must be authenticated as the AWS account root user, an IAM user, or by assuming an IAM role. You can sign in as a federated identity using credentials from an identity source like AWS IAM Identity Center (IAM Identity Center), single sign-on authentication, or Google/Facebook credentials. For more information about signing in, see [How to sign in to your AWS account](https://docs.aws.amazon.com/signin/latest/userguide/how-to-sign-in.html) in the *AWS Sign-In User Guide*. For programmatic access, AWS provides an SDK and CLI to cryptographically sign requests. For more information, see [AWS Signature Version 4 for API requests](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_sigv.html) in the *IAM User Guide*. ### AWS account root user When you create an AWS account, you begin with one sign-in identity called the AWS account *root user* that has complete access to all AWS services and resources. We strongly recommend that you don't use the root user for everyday tasks. For tasks that require root user credentials, see [Tasks that require root user credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_root-user.html#root-user-tasks) in the *IAM User Guide*. ### IAM users and groups An *[IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users.html)* is an identity with specific permissions for a single person or application. We recommend using temporary credentials instead of IAM users with long-term credentials. For more information, see [Require human users to use federation with an identity provider to access AWS using temporary credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#bp-users-federation-idp) in the *IAM User Guide*. An [https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html) specifies a collection of IAM users and makes permissions easier to manage for large sets of users. For more information, see [Use cases for IAM users](https://docs.aws.amazon.com/IAM/latest/UserGuide/gs-identities-iam-users.html) in the *IAM User Guide*. ### IAM roles An *[IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html)* is an identity with specific permissions that provides temporary credentials. You can assume a role by [switching from a user to an IAM role (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-console.html) or by calling an AWS CLI or AWS API operation. For more information, see [Methods to assume a role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_manage-assume.html) in the *IAM User Guide*. IAM roles are useful for federated user access, temporary IAM user permissions, cross-account access, cross-service access, and applications running on Amazon EC2. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*. ## Managing access using policies You control access in AWS by creating policies and attaching them to AWS identities or resources. A policy defines permissions when associated with an identity or resource. AWS evaluates these policies when a principal makes a request. Most policies are stored in AWS as JSON documents. For more information about JSON policy documents, see [Overview of JSON policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#access_policies-json) in the *IAM User Guide*. Using policies, administrators specify who has access to what by defining which **principal** can perform **actions** on what **resources**, and under what **conditions**. By default, users and roles have no permissions. An IAM administrator creates IAM policies and adds them to roles, which users can then assume. IAM policies define permissions regardless of the method used to perform the operation. ### Identity-based policies Identity-based policies are JSON permissions policy documents that you attach to an identity (user, group, or role). These policies control what actions identities can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see [Define custom IAM permissions with customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*. Identity-based policies can be *inline policies* (embedded directly into a single identity) or *managed policies* (standalone policies attached to multiple identities). To learn how to choose between managed and inline policies, see [Choose between managed policies and inline policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-choosing-managed-or-inline.html) in the *IAM User Guide*. ### Resource-based policies Resource-based policies are JSON policy documents that you attach to a resource. Examples include IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy. Resource-based policies are inline policies that are located in that service. You can't use AWS managed policies from IAM in a resource-based policy. ### Access control lists (ACLs) Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format. Amazon S3, AWS WAF, and Amazon VPC are examples of services that support ACLs. To learn more about ACLs, see [Access control list (ACL) overview](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html) in the *Amazon Simple Storage Service Developer Guide*. ### Other policy types AWS supports additional policy types that can set the maximum permissions granted by more common policy types: + **Permissions boundaries** – Set the maximum permissions that an identity-based policy can grant to an IAM entity. For more information, see [Permissions boundaries for IAM entities](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html) in the *IAM User Guide*. + **Service control policies (SCPs)** – Specify the maximum permissions for an organization or organizational unit in AWS Organizations. For more information, see [Service control policies](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_scps.html) in the *AWS Organizations User Guide*. + **Resource control policies (RCPs)** – Set the maximum available permissions for resources in your accounts. For more information, see [Resource control policies (RCPs)](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_rcps.html) in the *AWS Organizations User Guide*. + **Session policies** – Advanced policies passed as a parameter when creating a temporary session for a role or federated user. For more information, see [Session policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session) in the *IAM User Guide*. ### Multiple policy types When multiple types of policies apply to a request, the resulting permissions are more complicated to understand. To learn how AWS determines whether to allow a request when multiple policy types are involved, see [Policy evaluation logic](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.html) in the *IAM User Guide*. # How App Runner works with IAM Before you use IAM to manage access to AWS App Runner, you should understand what IAM features are available to use with App Runner. To get a high-level view of how App Runner and other AWS services work with IAM, see [AWS Services That Work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) in the *IAM User Guide*. For other App Runner security topics, see [Security in App Runner](security.md). **Topics** + [App Runner identity-based policies](#security_iam_service-with-iam-id-based-policies) + [App Runner resource-based policies](#security_iam_service-with-iam-resource-based-policies) + [Authorization based on App Runner tags](#security_iam_service-with-iam-tags) + [App Runner user permissions](#security_iam_service-with-iam-users) + [App Runner IAM roles](#security_iam_service-with-iam-roles) ## App Runner identity-based policies With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. App Runner supports specific actions, resources, and condition keys. To learn about all of the elements that you use in a JSON policy, see [IAM JSON Policy Elements Reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html) in the *IAM User Guide*. ### Actions Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**. The `Action` element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation. Policy actions in App Runner use the following prefix before the action: `apprunner:`. For example, to grant someone permission to run an Amazon EC2 instance with the Amazon EC2 `RunInstances` API operation, you include the `ec2:RunInstances` action in their policy. Policy statements must include either an `Action` or `NotAction` element. App Runner defines its own set of actions that describe tasks that you can perform with this service. To specify multiple actions in a single statement, separate them with commas as follows: ``` "Action": [ "apprunner:CreateService", "apprunner:CreateConnection" ] ``` You can specify multiple actions using wildcards (\$1). For example, to specify all actions that begin with the word `Describe`, include the following action: ``` "Action": "apprunner:Describe*" ``` To see a list of App Runner actions, see [Actions defined by AWS App Runner](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsapprunner.html#awsapprunner-actions-as-permissions) in the *Service Authorization Reference*. ### Resources Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**. The `Resource` JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference-arns.html). For actions that don't support resource-level permissions, use a wildcard (\$1) to indicate that the statement applies to all resources. ``` "Resource": "*" ``` App Runner resources have the following ARN structure: ``` arn:aws:apprunner:region:account-id:resource-type/resource-name[/resource-id] ``` For more information about the format of ARNs, see [Amazon Resource Names (ARNs) and AWS Service Namespaces](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) in the *AWS General Reference*. For example, to specify the `my-service` service in your statement, use the following ARN: ``` "Resource": "arn:aws:apprunner:us-east-1:123456789012:service/my-service" ``` To specify all services that belong to a specific account, use the wildcard (\$1): ``` "Resource": "arn:aws:apprunner:us-east-1:123456789012:service/*" ``` Some App Runner actions, such as those for creating resources, cannot be performed on a specific resource. In those cases, you must use the wildcard (\$1). ``` "Resource": "*" ``` To see a list of App Runner resource types and their ARNs, see [Resources defined by AWS App Runner](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsapprunner.html#awsapprunner-resources-for-iam-policies) in the *Service Authorization Reference*. To learn with which actions you can specify the ARN of each resource, see [Actions defined by AWS App Runner](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsapprunner.html#awsapprunner-actions-as-permissions). ### Condition keys Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**. The `Condition` element specifies when statements execute based on defined criteria. You can create conditional expressions that use [condition operators](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html), such as equals or less than, to match the condition in the policy with values in the request. To see all AWS global condition keys, see [AWS global condition context keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html) in the *IAM User Guide*. App Runner supports using some global condition keys. To see all AWS global condition keys, see [AWS Global Condition Context Keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html) in the *IAM User Guide*. App Runner defines a set of service-specific condition keys. In addition, App Runner supports tag-based access control, which is implemented using condition keys. For details, see [Authorization based on App Runner tags](#security_iam_service-with-iam-tags). To see a list of App Runner condition keys, see [Condition keys for AWS App Runner](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsapprunner.html#awsapprunner-policy-keys) in the *Service Authorization Reference*. To learn with which actions and resources you can use a condition key, see [Actions defined by AWS App Runner](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsapprunner.html#awsapprunner-actions-as-permissions). ### Examples To view examples of App Runner identity-based policies, see [App Runner identity-based policy examples](security_iam_id-based-policy-examples.md). ## App Runner resource-based policies App Runner does not support resource-based policies. ## Authorization based on App Runner tags You can attach tags to App Runner resources or pass tags in a request to App Runner. To control access based on tags, you provide tag information in the [condition element](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) of a policy using the `apprunner:ResourceTag/key-name`, `aws:RequestTag/key-name`, or `aws:TagKeys` condition keys. For more information about tagging App Runner resources, see [Configuring an App Runner service](manage-configure.md). To view an example identity-based policy for limiting access to a resource based on the tags on that resource, see [Controlling access to App Runner services based on tags](security_iam_id-based-policy-examples.md#security_iam_id-based-policy-examples-view-widget-tags). ## App Runner user permissions To use App Runner, IAM users need permissions to App Runner actions. A common way to grant permissions to users is by attaching a policy to IAM users or groups. For more information about managing user permissions, see [Changing permissions for an IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_change-permissions.html) in the *IAM User Guide*. App Runner provides two managed policies that you can attach to your users. + [https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerReadOnlyAccess.html](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerReadOnlyAccess.html) – Grants permissions to list and view details about App Runner resources. + [https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerFullAccess.html](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerFullAccess.html)– Grants permissions to all App Runner actions. For more granular control of user permissions, you can create a custom policy and attach it to your users. For details, see [Creating IAM policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*. For examples of user policies, see [User policies](security_iam_id-based-policy-examples.md#security_iam_id-based-policy-examples-users). ## App Runner IAM roles An [IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) is an entity within your AWS account that has specific permissions. ### Service-linked roles [Service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role) allow AWS services to access resources in other services to complete an action on your behalf. Service-linked roles appear in your IAM account and are owned by the service. An IAM administrator can view but not edit the permissions for service-linked roles. App Runner supports service-linked roles. For information about creating or managing App Runner service-linked roles, see [Using service-linked roles for App Runner](security-iam-slr.md). ### Service roles This feature allows a service to assume a [service role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-role) on your behalf. This role allows the service to access resources in other services to complete an action on your behalf. Service roles appear in your IAM account and are owned by the account. This means that an IAM user can change the permissions for this role. However, doing so might break the functionality of the service. App Runner supports a few service roles. #### Access role The access role is a role that App Runner uses for accessing images in Amazon Elastic Container Registry (Amazon ECR) in your account. It's required to access an image in Amazon ECR, and isn't required with Amazon ECR Public. Before creating a service based on an image in Amazon ECR, use IAM to create a service role. Use the managed policy [https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerServicePolicyForECRAccess.html](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSAppRunnerServicePolicyForECRAccess.html) in your service role. You can then pass this role to App Runner when you call the [CreateService](https://docs.aws.amazon.com/apprunner/latest/api/API_CreateService.html) API in the [AuthenticationConfiguration](https://docs.aws.amazon.com/apprunner/latest/api/API_AuthenticationConfiguration.html) member of the [SourceConfiguration](https://docs.aws.amazon.com/apprunner/latest/api/API_SourceConfiguration.html) parameter, or when you use the App Runner console to create a service. **Note** If you create your own custom policy for your access role, be sure to specify `"Resource": "*"` for the `ecr:GetAuthorizationToken` action. Tokens can be used to access any Amazon ECR registry that you have access to. When you create your access role, be sure to add a trust policy that declares the App Runner service principal `build.apprunner.amazonaws.com` as a trusted entity. ##### Trust policy for an access role ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "build.apprunner.amazonaws.com" }, "Action": "sts:AssumeRole" } ] } ``` ------ If you use the App Runner console to create a service, the console can automatically create an access role for you and choose it for the new service. The console also lists other roles in your account, and you can select a different role if you like. #### Instance role The instance role is an optional role that App Runner uses to provide permissions to AWS service actions that your service's compute instances need. You need to provide an instance role to App Runner if your application code calls AWS actions (APIs). Either embed the required permissions in your instance role or create your own custom policy and use it in the instance role. We have no way to anticipate which calls your code uses. Therefore, we don't provide a managed policy for this purpose. Before creating an App Runner service, use IAM to create a service role with the required custom or embedded policies. You can then pass this role to App Runner as the instance role when you call the [CreateService](https://docs.aws.amazon.com/apprunner/latest/api/API_CreateService.html) API in the `InstanceRoleArn` member of the [InstanceConfiguration](https://docs.aws.amazon.com/apprunner/latest/api/API_InstanceConfiguration.html) parameter, or when you use the App Runner console to create a service. When you create your instance role, be sure to add a trust policy that declares the App Runner service principal `tasks.apprunner.amazonaws.com` as a trusted entity. ##### Trust policy for an instance role ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "tasks.apprunner.aws.com" }, "Action": "sts:AssumeRole" } ] } ``` ------ If you use the App Runner console to create a service, the console lists the roles in your account, and you can select the role that you created for this purpose. For information about creating a service, see [Creating an App Runner service](manage-create.md). # App Runner identity-based policy examples By default, IAM users and roles don't have permission to create or modify AWS App Runner resources. They also can't perform tasks using the AWS Management Console, AWS CLI, or AWS API. An IAM administrator must create IAM policies that grant users and roles permission to perform specific API operations on the specified resources they need. The administrator must then attach those policies to the IAM users or groups that require those permissions. To learn how to create an IAM identity-based policy using these example JSON policy documents, see [Creating Policies on the JSON Tab](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html#access_policies_create-json-editor) in the *IAM User Guide*. For other App Runner security topics, see [Security in App Runner](security.md). **Topics** + [Policy best practices](#security_iam_service-with-iam-policy-best-practices) + [User policies](#security_iam_id-based-policy-examples-users) + [Controlling access to App Runner services based on tags](#security_iam_id-based-policy-examples-view-widget-tags) ## Policy best practices Identity-based policies determine whether someone can create, access, or delete App Runner resources in your account. These actions can incur costs for your AWS account. When you create or edit identity-based policies, follow these guidelines and recommendations: + **Get started with AWS managed policies and move toward least-privilege permissions** – To get started granting permissions to your users and workloads, use the *AWS managed policies* that grant permissions for many common use cases. They are available in your AWS account. We recommend that you reduce permissions further by defining AWS customer managed policies that are specific to your use cases. For more information, see [AWS managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) or [AWS managed policies for job functions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_job-functions.html) in the *IAM User Guide*. + **Apply least-privilege permissions** – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as *least-privilege permissions*. For more information about using IAM to apply permissions, see [ Policies and permissions in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) in the *IAM User Guide*. + **Use conditions in IAM policies to further restrict access** – You can add a condition to your policies to limit access to actions and resources. For example, you can write a policy condition to specify that all requests must be sent using SSL. You can also use conditions to grant access to service actions if they are used through a specific AWS service, such as CloudFormation. For more information, see [ IAM JSON policy elements: Condition](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) in the *IAM User Guide*. + **Use IAM Access Analyzer to validate your IAM policies to ensure secure and functional permissions** – IAM Access Analyzer validates new and existing policies so that the policies adhere to the IAM policy language (JSON) and IAM best practices. IAM Access Analyzer provides more than 100 policy checks and actionable recommendations to help you author secure and functional policies. For more information, see [Validate policies with IAM Access Analyzer](https://docs.aws.amazon.com/IAM/latest/UserGuide/access-analyzer-policy-validation.html) in the *IAM User Guide*. + **Require multi-factor authentication (MFA)** – If you have a scenario that requires IAM users or a root user in your AWS account, turn on MFA for additional security. To require MFA when API operations are called, add MFA conditions to your policies. For more information, see [ Secure API access with MFA](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_mfa_configure-api-require.html) in the *IAM User Guide*. For more information about best practices in IAM, see [Security best practices in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the *IAM User Guide*. ## User policies To access the App Runner console, IAM users must have a minimum set of permissions. These permissions must allow you to list and view details about the App Runner resources in your AWS account. If you create an identity-based policy that is more restrictive than the minimum required permissions, the console won't function as intended for users with that policy. App Runner provides two managed policies that you can attach to your users. + `AWSAppRunnerReadOnlyAccess` – Grants permissions to list and view details about App Runner resources. + `AWSAppRunnerFullAccess` – Grants permissions to all App Runner actions. To ensure that users can use the App Runner console, attach, at a minimum, the `AWSAppRunnerReadOnlyAccess` managed policy to the users. You can attach the `AWSAppRunnerFullAccess` managed policy instead, or add specific additional permissions, to allow users to create, modify, and delete resource. For more information, see [Adding Permissions to a User](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_change-permissions.html#users_change_permissions-add-console) in the *IAM User Guide*. You don't need to allow minimum console permissions for users that are making calls only to the AWS CLI or the AWS API. Instead, allow access to only the actions that match the API operation that you want to allow users to perform. The following examples demonstrate custom user policies. You can use them as starting points to defining your own custom user policies. Copy the example, and or remove actions, scope down resources, and add conditions. ### Example: console and connection management user policy This example policy enables console access and allows connection creation and management. It doesn't allow App Runner service creation and management. It can be attached to a user whose role is to manage App Runner service access to source code assets. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "apprunner:List*", "apprunner:Describe*", "apprunner:CreateConnection", "apprunner:DeleteConnection" ], "Resource": "*" } ] } ``` ------ ### Example: user policies that use condition keys The examples in this section demonstrate conditional permissions that depend on some resource properties or action parameters. This example policy enables creating an App Runner service but denies using a connection named `prod`. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Sid": "AllowCreateAppRunnerServiceWithNonProdConnections", "Effect": "Allow", "Action": "apprunner:CreateService", "Resource": "*", "Condition": { "ArnNotLike": {"apprunner:ConnectionArn":"arn:aws:apprunner:*:*:connection/prod/*"} } } ] } ``` ------ This example policy enables updating an App Runner service named `preprod` only with an auto scaling configuration named `preprod`. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Sid": "AllowUpdatePreProdAppRunnerServiceWithPreProdASConfig", "Effect": "Allow", "Action": "apprunner:UpdateService", "Resource": "arn:aws:apprunner:*:*:service/preprod/*", "Condition": { "ArnLike": { "apprunner:AutoScalingConfigurationArn": "arn:aws:apprunner:us-east-1:*:autoscalingconfiguration/preprod/*" } } } ] } ``` ------ ## Controlling access to App Runner services based on tags You can use conditions in your identity-based policy to control access to App Runner resources based on tags. This example shows how you might create a policy that allows deleting an App Runner service. However, permission is granted only if the service tag `Owner` has the value of that user's user name. This policy also grants the permissions necessary to complete this action on the console. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Sid": "ListServicesInConsole", "Effect": "Allow", "Action": "apprunner:ListServices", "Resource": "*" }, { "Sid": "DeleteServiceIfOwner", "Effect": "Allow", "Action": "apprunner:DeleteService", "Resource": "arn:aws:apprunner:us-east-1:*:service/*", "Condition": { "StringEquals": {"aws:ResourceTag/Owner": "${aws:username}"} } } ] } ``` ------ You can attach this policy to the IAM users in your account. If a user named `richard-roe` attempts to delete an App Runner service, the service must be tagged `Owner=richard-roe` or `owner=richard-roe`. Otherwise he is denied access. The condition tag key `Owner` matches both `Owner` and `owner` because condition key names are not case-sensitive. For more information, see [IAM JSON Policy Elements: Condition](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) in the *IAM User Guide*. # Using service-linked roles for App Runner AWS App Runner uses AWS Identity and Access Management (IAM)[ service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role).

App Runner defines the permissions of its service-linked roles, and unless defined otherwise, only App Runner can assume its roles. The defined permissions include the trust policy and the permissions policy, and that permissions policy cannot be attached to any other IAM entity. You can delete a service-linked role only after first deleting their related resources. This protects your App Runner resources because you can't inadvertently remove permission to access the resources. For information about other services that support service-linked roles, see [AWS Services That Work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) and look for the services that have **Yes **in the **Service-Linked Role** column.

For more information, see [Editing a Service-Linked Role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#edit-service-linked-role) in the *IAM User Guide*. ## Deleting a service-linked role for App Runner If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don’t have an unused entity that is not actively monitored or maintained. However, you must clean up your service-linked role before you can manually delete it. ### Cleaning up a service-linked role Before you can use IAM to delete a service-linked role, you must first delete any resources used by the role. In App Runner, this means deleting all App Runner services in your account. To learn about deleting App Runner services, see [Deleting an App Runner service](manage-delete.md). **Note** If the App Runner service is using the role when you try to delete the resources, then the deletion might fail. If that happens, wait for a few minutes and try the operation again. ### Manually delete the service-linked role Use the IAM console, the AWS CLI, or the AWS API to delete the AWSServiceRoleForAppRunner service-linked role.

For more information, see [AWS App Runner endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/apprunner.html) in the *AWS General Reference*. # AWS managed policies for AWS App Runner An AWS managed policy is a standalone policy that is created and administered by AWS. AWS managed policies are designed to provide permissions for many common use cases so that you can start assigning permissions to users, groups, and roles. Keep in mind that AWS managed policies might not grant least-privilege permissions for your specific use cases because they're available for all AWS customers to use. We recommend that you reduce permissions further by defining [ customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#customer-managed-policies) that are specific to your use cases. You cannot change the permissions defined in AWS managed policies. If AWS updates the permissions defined in an AWS managed policy, the update affects all principal identities (users, groups, and roles) that the policy is attached to. AWS is most likely to update an AWS managed policy when a new AWS service is launched or new API operations become available for existing services. For more information, see [AWS managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) in the *IAM User Guide*. ## App Runner updates to AWS managed policies View details about updates to AWS managed policies for App Runner since this service began tracking these changes.

For other App Runner security topics, see [Security in App Runner](security.md). **Topics** + [I'm not authorized to perform an action in App Runner](#security_iam_troubleshoot-no-permissions) + [I want to allow people outside of my AWS account to access my App Runner resources](#security_iam_troubleshoot-cross-account-access) ## I'm not authorized to perform an action in App Runner If the AWS Management Console tells you that you're not authorized to perform an action, contact your administrator for assistance. Your administrator is the person that provided you with your AWS sign-in credentials. The following example error occurs when an IAM user named `marymajor` tries to use the console to view details about an App Runner service but doesn't have `apprunner:DescribeService` permissions. ``` User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: apprunner:DescribeService on resource: my-example-service ``` In this case, Mary asks her administrator to update her policies to allow her to access the `my-example-service` resource using the `apprunner:DescribeService` action. ## I want to allow people outside of my AWS account to access my App Runner resources You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources. To learn more, consult the following: + To learn whether App Runner supports these features, see [How App Runner works with IAM](security_iam_service-with-iam.md). + To learn how to provide access to your resources across AWS accounts that you own, see [Providing access to an IAM user in another AWS account that you own](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_aws-accounts.html) in the *IAM User Guide*. + To learn how to provide access to your resources to third-party AWS accounts, see [Providing access to AWS accounts owned by third parties](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_third-party.html) in the *IAM User Guide*. + To learn how to provide access through identity federation, see [Providing access to externally authenticated users (identity federation)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_federated-users.html) in the *IAM User Guide*. + To learn the difference between using roles and resource-based policies for cross-account access, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*. # Logging and monitoring in App Runner Monitoring is an important part of maintaining the reliability, availability, and performance of your AWS App Runner service. Collecting monitoring data from all parts of your AWS solution allows you to more easily debug a failure if one occurs. App Runner integrates with several AWS tools for monitoring your App Runner services and responding to potential incidents. **Amazon CloudWatch alarms** With Amazon CloudWatch alarms, you can watch a service metric over a time period that you specify. If the metric exceeds a given threshold for a given number of periods, you receive a notification. App Runner collects a variety of metrics about the service as a whole and the instances (scaling units) that run your web service. For more information, see [Metrics (CloudWatch)](monitor-cw.md). **Application logs** App Runner collects the output of your application code and streams it to Amazon CloudWatch Logs. What's in this output is up to you. For example, you could include detailed records of requests made to your web service. These log records might prove useful in security and access audits. For more information, see [Logs (CloudWatch Logs)](monitor-cwl.md). **AWS CloudTrail action logs** App Runner is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in App Runner. CloudTrail captures all API calls for App Runner as events. You can view the most recent events in the CloudTrail console, and you can create a trail to enable continuous delivery of CloudTrail events to an Amazon Simple Storage Service (Amazon S3) bucket. For more information, see [API actions (CloudTrail)](monitor-ct.md). # Compliance validation for App Runner Third-party auditors assess the security and compliance of AWS App Runner as part of multiple AWS compliance programs. These include SOC, PCI, FedRAMP, HIPAA, and others. To learn whether an AWS service is within the scope of specific compliance programs, see [AWS services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/) and choose the compliance program that you are interested in. For general information, see [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/). You can download third-party audit reports using AWS Artifact. For more information, see [Downloading Reports in AWS Artifact](https://docs.aws.amazon.com/artifact/latest/ug/downloading-documents.html). Your compliance responsibility when using AWS services is determined by the sensitivity of your data, your company's compliance objectives, and applicable laws and regulations. For more information about your compliance responsibility when using AWS services, see [AWS Security Documentation](https://docs.aws.amazon.com/security/). For other App Runner security topics, see [Security in App Runner](security.md). # Resilience in App Runner The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. For more information about AWS Regions and Availability Zones, see [AWS Global Infrastructure](https://aws.amazon.com/about-aws/global-infrastructure/). AWS App Runner manages and automates the use of the AWS global infrastructure on your behalf. When using App Runner, you benefit from the availability and fault tolerance mechanisms that AWS offers. For other App Runner security topics, see [Security in App Runner](security.md). # Infrastructure security in AWS App Runner As a managed service, AWS App Runner is protected by the AWS global network security procedures that are described in the [Amazon Web Services: Overview of Security Processes](https://d0.awsstatic.com/whitepapers/Security/AWS_Security_Whitepaper.pdf) whitepaper. You use AWS published API calls to manage and operate App Runner through the network. Clients that call App Runner APIs must support Transport Layer Security (TLS) 1.2 or later. Clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). Most modern systems such as Java 7 and later support these modes. These requirements do not apply to endpoints from App Runner applications. Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the [AWS Security Token Service](https://docs.aws.amazon.com/STS/latest/APIReference/Welcome.html) (AWS STS) to generate temporary security credentials to sign requests. For other App Runner security topics, see [Security in App Runner](security.md). # Using App Runner with VPC endpoints Your AWS application might integrate AWS App Runner services with other AWS services that run in a VPC from [Amazon Virtual Private Cloud](https://docs.aws.amazon.com/vpc/latest/userguide/) (Amazon VPC). Parts of your application might make requests to App Runner from within the VPC. For example, you might use AWS CodePipeline to continuously deploy to your App Runner service. One way to improve the security of your application is to send these App Runner requests (and requests to other AWS services) over a VPC endpoint. Using a *VPC endpoint*, you can privately connect your VPC to supported AWS services and VPC endpoint services that are powered by AWS PrivateLink. You don't need an internet gateway, NAT device, VPN connection, or Direct Connect connection. Resources in your VPC don't use public IP addresses to interact with App Runner resources. Traffic between your VPC and App Runner doesn't leave the Amazon network. For more information about VPC endpoints, see [VPC endpoints](https://docs.aws.amazon.com/vpc/latest/privatelink/vpc-endpoints.html) in the *AWS PrivateLink Guide*. **Note** By default, the web application in your App Runner service runs in a VPC that App Runner provides and configures. This VPC is public. It means that it's connected to the internet. You can optionally associate your application with a custom VPC. For more information, see [Enabling VPC access for outgoing traffic](network-vpc.md). You can configure your services to access the internet, including AWS APIs, even when your service is connected to a VPC. For instructions on how to enable public internet access for VPC outbound traffic, see [Considerations when selecting a subnet](network-vpc.md#network-vpc.considerations-subnet). App Runner doesn't support creating a VPC endpoint for your application. ## Setting up a VPC endpoint for App Runner To create the interface VPC endpoint for the App Runner service in your VPC, follow the [Create an interface endpoint](https://docs.aws.amazon.com/vpc/latest/privatelink/vpce-interface.html#create-interface-endpoint) procedure in the *AWS PrivateLink Guide*. For **Service Name**, choose `com.amazonaws.region.apprunner`. ## VPC network privacy considerations **Important** Using a VPC endpoint for App Runner doesn't ensure that all traffic from your VPC stays off of the internet. The VPC might be public. Moreover, some parts of your solution might not use VPC endpoints to make AWS API calls. For example, AWS services might call other services using their public endpoints. If traffic privacy is required for the solution in your VPC, read this section. To ensure privacy of network traffic in your VPC, consider the following: + *Enable DNS name* – Parts of your application might still send requests to App Runner over the internet using the `apprunner.region.amazonaws.com` public endpoint. If your VPC is configured with internet access, these requests succeed with no indication to you. You can prevent this by ensuring that **Enable DNS name** is enabled when you create the endpoint. By default, it's set to true. This adds a DNS entry in your VPC that maps the public service endpoint to the interface VPC endpoint. + *Configure VPC endpoints for additional services* – Your solution might send requests to other AWS services. For example, AWS CodePipeline might send requests to AWS CodeBuild. Configure VPC endpoints for these services, and enable DNS names on these endpoints. + *Configure a private VPC* – If possible (if your solution doesn't need internet access at all), set up your VPC as private, which means that it has no internet connection. This ensures that a missing VPC endpoint causes a visible error, so that you can add the missing endpoint. ## Using endpoint policies to control access with VPC endpoints VPC endpoint policies are supported for App Runner. By default, full access to App Runner is allowed through the interface endpoint. VPC endpoint policies can be used to control which AWS principals can access the App Runner endpoint. Alternatively, you can associate a security group with the endpoint network interfaces to control traffic to App Runner through the interface endpoint. ## Integrating with interface endpoint App Runner supports AWS PrivateLink, which provides private connectivity to App Runner and eliminates exposure of traffic to the internet. To enable your application to send requests to App Runner using AWS PrivateLink, configure a type of VPC endpoint known as an *interface endpoint*. For more information, see [Interface VPC endpoints (AWS PrivateLink)](https://docs.aws.amazon.com/vpc/latest/privatelink/vpce-interface.html) in the *AWS PrivateLink Guide*. # Configuration and vulnerability analysis in App Runner AWS and our customers share responsibility for achieving a high level of software component security and compliance. For more information, see the AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/). ## Patch container images Patching the container image is part of the customer's responsibility in the shared security model. The image owner is responsible for updating and regularly patching the container image. We recommend establishing a routine schedule for checking and applying updates to your container images. For more information on how to scan your images for vulnerabilities, see the [AWS App Runner Documentation](security-best-practices.md#security-best-practices.preventive.scan) For other App Runner security topics, see [Security in App Runner](security.md). # Security best practices for App Runner AWS App Runner provides several security features to consider as you develop and implement your own security policies. The following best practices are general guidelines and don’t represent a complete security solution. Because these best practices might not be appropriate or sufficient for your environment, treat them as helpful considerations, not prescriptions. For other App Runner security topics, see [Security in App Runner](security.md). ## Preventive security best practices Preventive security controls attempt to prevent incidents before they occur. ### Implement least privilege access App Runner provides AWS Identity and Access Management (IAM) managed policies for [IAM users](security_iam_id-based-policy-examples.md#security_iam_id-based-policy-examples-users) and the [access role](security_iam_service-with-iam.md#security_iam_service-with-iam-roles-service.access). These managed policies specify all permissions that might be necessary for the correct operation of your App Runner service. Your application might not require all the permissions in our managed policies. You can customize them and grant only the permissions that are required for your users and your App Runner service to perform their tasks. This is particularly relevant to user policies, where different user roles might have different permission needs. Implementing least privilege access is fundamental in reducing security risk and the impact that could result from errors or malicious intent. ### Scan your images for vulnerabilities You can use the Amazon ECR's APIs to help identify software vulnerabilities in your container images. For more information, see the [Amazon ECR documentation](https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-scanning.html). ## Detective security best practices Detective security controls identify security violations after they have occurred. They can help you detect a potential security threat or incident. ### Implement monitoring Monitoring is an important part of maintaining the reliability, security, availability, and performance of your App Runner solutions. AWS provides several tools and services to help you monitor your AWS services. The following are some examples of items to monitor: + *Amazon CloudWatch metrics for App Runner* – Set alarms for key App Runner metrics and for your application's custom metrics. For details, see [Metrics (CloudWatch)](monitor-cw.md). + *AWS CloudTrail entries* – Track actions that might impact availability, like `PauseService` or `DeleteConnection`. For details, see [API actions (CloudTrail)](monitor-ct.md).
