Operational Best Practices for K-ISMS
Conformance packs provide a general-purpose compliance framework designed to enable you to create security, operational or cost-optimization governance checks using managed or custom AWS Config rules and AWS Config remediation actions. Conformance Packs, as sample templates, are not designed to fully ensure compliance with a specific governance or compliance standard. You are responsible for making your own assessment of whether your use of the Services meets applicable legal and regulatory requirements.
The following provides a sample mapping between Korea – Information Security Management System (ISMS) and AWS managed Config rules. Each Config rule applies to a specific AWS resource, and relates to one or more Korea – ISMS controls. A Korea – ISMS control can be related to multiple Config rules. Refer to the table below for more detail and guidance related to these mappings.
| Control ID | AWS Config Rule | Guidance |
|---|---|---|
| 1.2.1 | Use AWS Systems Manager Associations to help with inventory of software platforms and applications within an organization. AWS Systems Manager assigns a configuration state to your managed instances and allows you to set baselines of operating system patch levels, software installations, application configurations, and other details about your environment. | |
| 1.2.1 | This rule ensures that Amazon Elastic Block Store volumes that are attached to Amazon Elastic Compute Cloud (Amazon EC2) instances are marked for deletion when an instance is terminated. If an Amazon EBS volume isn't deleted when the instance that it's attached to is terminated, it may violate the concept of least functionality. | |
| 2.1.3 | Use AWS Systems Manager Associations to help with inventory of software platforms and applications within an organization. AWS Systems Manager assigns a configuration state to your managed instances and allows you to set baselines of operating system patch levels, software installations, application configurations, and other details about your environment. | |
| 2.1.3 | This rule ensures that Amazon Elastic Block Store volumes that are attached to Amazon Elastic Compute Cloud (Amazon EC2) instances are marked for deletion when an instance is terminated. If an Amazon EBS volume isn't deleted when the instance that it's attached to is terminated, it may violate the concept of least functionality. | |
| 2.3.3 | Use Amazon CloudWatch to centrally collect and manage log event activity. Inclusion of AWS CloudTrail data provides details of API call activity within your AWS account. | |
| 2.3.3 | AWS CloudTrail can help in non-repudiation by recording AWS Management Console actions and API calls. You can identify the users and AWS accounts that called an AWS service, the source IP address where the calls generated, and the timings of the calls. Details of captured data are seen within AWS CloudTrail Record Contents. | |
| 2.5.1 | The credentials are audited for authorized devices, users, and processes by ensuring IAM access keys are rotated as specified by the organizational policy. Changing the access keys on a regular schedule is a security best practice. It shortens the period an access key is active and reduces the business impact if the keys are compromised. This rule requires an access key rotation value (Config Default: 90). The actual value should reflect your organization's policies. | |
| 2.5.1 | The access permissions and authorizations can be managed and incorporated with the principles of least privilege and separation of duties, by enabling Kerberos for Amazon EMR clusters. In Kerberos, the services and the users that need to authenticate are known as principals. The principals exist within a Kerberos realm. Within the realm, a Kerberos server is known as the key distribution center (KDC). It provides a means for the principals to authenticate. The KDC authenticates by issuing tickets for authentication. The KDC maintains a database of the principals within its realm, their passwords, and other administrative information about each principal. | |
| 2.5.1 | AWS Identity and Access Management (IAM) can help you incorporate the principles of least privilege and separation of duties with access permissions and authorizations, restricting policies from containing blocked actions on all AWS Key Management Service keys. Having more privileges than needed to complete a task may violate the principle of least privilege and separation of duties. This rule allows you to set the blockedActionsPatterns parameter. (AWS Foundational Security Best Practices value: kms:Decrypt, kms:ReEncryptFrom). The actual values should reflect your organization's policies | |
| 2.5.1 | AWS Identity and Access Management (IAM) can help you incorporate the principles of least privilege and separation of duties with access permissions and authorizations, by ensuring that IAM groups have at least one user. Placing users in groups based on their associated permissions or job function is one way to incorporate least privilege. | |
| 2.5.1 | Ensure an AWS Identity and Access Management (IAM) user, IAM role or IAM group does not have an inline policy to allow blocked actions on all AWS Key Management Service keys. AWS recommends to use managed policies instead of inline policies. The managed policies allow reusability, versioning, rolling back, and delegating permissions management. This rule allows you to set the blockedActionsPatterns parameter. (AWS Foundational Security Best Practices value: kms:Decrypt, kms:ReEncryptFrom). The actual values should reflect your organization's policies. | |
| 2.5.1 | AWS Identity and Access Management (IAM) can help you incorporate the principles of least privilege and separation of duties with access permissions and authorizations, restricting policies from containing "Effect": "Allow" with "Action": "*" over "Resource": "*". Allowing users to have more privileges than needed to complete a task may violate the principle of least privilege and separation of duties. | |
| 2.5.1 | Ensure IAM Actions are restricted to only those actions that are needed. Allowing users to have more privileges than needed to complete a task may violate the principle of least privilege and separation of duties. | |
| 2.5.1 | Access to systems and assets can be controlled by checking that the root user does not have access keys attached to their AWS Identity and Access Management (IAM) role. Ensure that the root access keys are deleted. Instead, create and use role-based AWS accounts to help to incorporate the principle of least functionality. | |
| 2.5.1 | Enable this rule to restrict access to resources in the AWS Cloud. This rule ensures multi-factor authentication (MFA) is enabled for all users. MFA adds an extra layer of protection on top of sign-in credentials. Reduce the incidents of compromised accounts by requiring MFA for users. | |
| 2.5.1 | This rule ensures AWS Identity and Access Management (IAM) policies are attached only to groups or roles to control access to systems and assets. Assigning privileges at the group or the role level helps to reduce opportunity for an identity to receive or retain excessive privileges. | |
| 2.5.1 | AWS Identity and Access Management (IAM) can help you with access permissions and authorizations by checking for IAM passwords and access keys that are not used for a specified time period. If these unused credentials are identified, you should disable and/or remove the credentials, as this may violate the principle of least privilege. This rule requires you to set a value to the maxCredentialUsageAge (Config Default: 90). The actual value should reflect your organization's policies. | |
| 2.5.1 | Manage access to resources in the AWS Cloud by ensuring that MFA is enabled for all AWS Identity and Access Management (IAM) users that have a console password. MFA adds an extra layer of protection on top of sign-in credentials. By requiring MFA for users, you can reduce incidents of compromised accounts and keep sensitive data from being accessed by unauthorized users. | |
| 2.5.1 | Manage access to resources in the AWS Cloud by ensuring MFA is enabled for the root user. The root user is the most privileged user in an AWS account. The MFA adds an extra layer of protection for sign-in credentials. By requiring MFA for the root user, you can reduce the incidents of compromised AWS accounts. | |
| 2.5.1 | To help protect data at rest, ensure encryption with AWS Key Management Service (AWS KMS) is enabled for AWS Secrets Manager secrets. Because sensitive data can exist at rest in Secrets Manager secrets, enable encryption at rest to help protect that data. | |
| 2.5.3 | Enable this rule to restrict access to resources in the AWS Cloud. This rule ensures multi-factor authentication (MFA) is enabled for all users. MFA adds an extra layer of protection on top of sign-in credentials. Reduce the incidents of compromised accounts by requiring MFA for users. | |
| 2.5.3 | Manage access to resources in the AWS Cloud by ensuring that MFA is enabled for all AWS Identity and Access Management (IAM) users that have a console password. MFA adds an extra layer of protection on top of sign-in credentials. By requiring MFA for users, you can reduce incidents of compromised accounts and keep sensitive data from being accessed by unauthorized users. | |
| 2.5.3 | Manage access to resources in the AWS Cloud by ensuring MFA is enabled for the root user. The root user is the most privileged user in an AWS account. The MFA adds an extra layer of protection for sign-in credentials. By requiring MFA for the root user, you can reduce the incidents of compromised AWS accounts. | |
| 2.5.4 | The identities and the credentials are issued, managed, and verified based on an organizational IAM password policy. They meet or exceed requirements as stated by NIST SP 800-63 and the AWS Foundational Security Best Practices standard for password strength. This rule allows you to optionally set RequireUppercaseCharacters (AWS Foundational Security Best Practices value: true), RequireLowercaseCharacters (AWS Foundational Security Best Practices value: true), RequireSymbols (AWS Foundational Security Best Practices value: true), RequireNumbers (AWS Foundational Security Best Practices value: true), MinimumPasswordLength (AWS Foundational Security Best Practices value: 14), PasswordReusePrevention (AWS Foundational Security Best Practices value: 24), and MaxPasswordAge (AWS Foundational Security Best Practices value: 90) for your IAM Password Policy. The actual values should reflect your organization's policies. | |
| 2.5.5 | EC2 instance profiles pass an IAM role to an EC2 instance. Attaching an instance profile to your instances can assist with least privilege and permissions management. | |
| 2.5.5 | Access to systems and assets can be controlled by checking that the root user does not have access keys attached to their AWS Identity and Access Management (IAM) role. Ensure that the root access keys are deleted. Instead, create and use role-based AWS accounts to help to incorporate the principle of least functionality. | |
| 2.5.5 | Manage access to resources in the AWS Cloud by ensuring MFA is enabled for the root user. The root user is the most privileged user in an AWS account. The MFA adds an extra layer of protection for sign-in credentials. By requiring MFA for the root user, you can reduce the incidents of compromised AWS accounts. | |
| 2.6 | Ensure AWS WAF is enabled on Elastic Load Balancers (ELB) to help protect web applications. A WAF helps to protect your web applications or APIs against common web exploits. These web exploits may affect availability, compromise security, or consume excessive resources within your environment. | |
| 2.6 | Deploy Amazon Elastic Compute Cloud (Amazon EC2) instances within an Amazon Virtual Private Cloud (Amazon VPC) to enable secure communication between an instance and other services within the amazon VPC, without requiring an internet gateway, NAT device, or VPN connection. All traffic remains securely within the AWS Cloud. Because of their logical isolation, domains that reside within an Amazon VPC have an extra layer of security when compared to domains that use public endpoints. Assign Amazon EC2 instances to an Amazon VPC to properly manage access. | |
| 2.6 | Manage access to the AWS Cloud by ensuring EBS snapshots are not publicly restorable. EBS volume snapshots can contain sensitive information and access control is required for such accounts. | |
| 2.6 | Manage access to the AWS Cloud by ensuring Amazon Elastic Compute Cloud (Amazon EC2) instances cannot be publicly accessed. Amazon EC2 instances can contain sensitive information and access control is required for such accounts. | |
| 2.6 | Enable this rule to restrict access to resources in the AWS Cloud. This rule ensures multi-factor authentication (MFA) is enabled for all users. MFA adds an extra layer of protection on top of sign-in credentials. Reduce the incidents of compromised accounts by requiring MFA for users. | |
| 2.6 | Amazon Elastic Compute Cloud (Amazon EC2) Security Groups can help manage network access by providing stateful filtering of ingress and egress network traffic to AWS resources. Not allowing ingress (or remote) traffic from 0.0.0.0/0 to port 22 on your resources help you restricting remote access. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring AWS Lambda functions cannot be publicly accessed. Public access can potentially lead to degradation of availability of resources. | |
| 2.6 | Deploy AWS Lambda functions within an Amazon Virtual Private Cloud (Amazon VPC) for a secure communication between a function and other services within the Amazon VPC. With this configuration, there is no requirement for an internet gateway, NAT device, or VPN connection. All the traffic remains securely within the AWS Cloud. Because of their logical isolation, domains that reside within an Amazon VPC have an extra layer of security when compared to domains that use public endpoints. To properly manage access, AWS Lambda functions should be assigned to a VPC. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring that MFA is enabled for all AWS Identity and Access Management (IAM) users that have a console password. MFA adds an extra layer of protection on top of sign-in credentials. By requiring MFA for users, you can reduce incidents of compromised accounts and keep sensitive data from being accessed by unauthorized users. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring that Amazon Relational Database Service (Amazon RDS) instances are not public. Amazon RDS database instances can contain sensitive information, and principles and access control is required for such accounts. | |

| 2.6 | Manage access to resources in the AWS Cloud by ensuring that Amazon Redshift clusters are not public. Amazon Redshift clusters can contain sensitive information and principles and access control is required for such accounts. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring common ports are restricted on Amazon Elastic Compute Cloud (Amazon EC2) security groups. Not restricting access to ports to trusted sources can lead to attacks against the availability, integrity and confidentiality of systems. This rule allows you to optionally set blockedPort1 - blockedPort5 parameters (Config Defaults: 20,21,3389,3306,4333). The actual values should reflect your organization's policies. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring MFA is enabled for the root user. The root user is the most privileged user in an AWS account. The MFA adds an extra layer of protection for sign-in credentials. By requiring MFA for the root user, you can reduce the incidents of compromised AWS accounts. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring that Amazon Simple Storage Service (Amazon S3) buckets cannot be publicly accessed. This rule helps keeping sensitive data safe from unauthorized remote users by preventing public access. This rule allows you to optionally set the ignorePublicAcls (Config Default: True), blockPublicPolicy (Config Default: True), blockPublicAcls (Config Default: True), and restrictPublicBuckets parameters (Config Default: True). The actual values should reflect your organization's policies. | |
| 2.6 | Manage access to resources in the AWS Cloud by only allowing authorized users, processes, and devices access to Amazon Simple Storage Service (Amazon S3) buckets. The management of access should be consistent with the classification of the data. | |
| 2.6 | Manage access to resources in the AWS Cloud by only allowing authorized users, processes, and devices access to Amazon Simple Storage Service (Amazon S3) buckets. The management of access should be consistent with the classification of the data. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring that Amazon SageMaker notebooks do not allow direct internet access. By preventing direct internet access, you can keep sensitive data from being accessed by unauthorized users. | |
| 2.6 | Amazon Elastic Compute Cloud (Amazon EC2) security groups can help in the management of network access by providing stateful filtering of ingress and egress network traffic to AWS resources. Restricting all the traffic on the default security group helps in restricting remote access to your AWS resources. | |
| 2.6 | Manage access to resources in the AWS Cloud by ensuring common ports are restricted on Amazon Elastic Compute Cloud (Amazon EC2) Security Groups. Not restricting access on ports to trusted sources can lead to attacks against the availability, integrity and confidentiality of systems. By restricting access to resources within a security group from the internet (0.0.0.0/0) remote access can be controlled to internal systems. | |
| 2.6.6 | AWS WAF enables you to configure a set of rules (called a web access control list (web ACL)) that allow, block, or count web requests based on customizable web security rules and conditions that you define. Ensure your Amazon API Gateway stage is associated with a WAF Web ACL to protect it from malicious attacks | |
| 2.6.6 | Because sensitive data can exist and to help protect data at transit, ensure encryption is enabled for your Elastic Load Balancing. Use AWS Certificate Manager to manage, provision and deploy public and private SSL/TLS certificates with AWS services and internal resources. | |

| 2.7 | Because sensitive data may exist and to help protect data at rest, ensure encryption is enabled for your AWS CloudTrail trails. | |
| 2.7 | Ensure that encryption is enabled for your Amazon DynamoDB tables. Because sensitive data can exist at rest in these tables, enable encryption at rest to help protect that data. By default, DynamoDB tables are encrypted with an AWS owned customer master key (CMK). | |
| 2.7 | To help protect data at rest, ensure that encryption is enabled for your Amazon Elastic Block Store (Amazon EBS) volumes. Because sensitive data can exist at rest in these volumes, enable encryption at rest to help protect that data. | |
| 2.7 | Because sensitive data can exist and to help protect data at rest, ensure encryption is enabled for your Amazon Elastic File System (EFS). | |
| 2.7 | Because sensitive data can exist and to help protect data at rest, ensure encryption is enabled for your Amazon OpenSearch Service (OpenSearch Service) domains. | |
| 2.7 | Ensure node-to-node encryption for Amazon OpenSearch Service is enabled. Node-to-node encryption enables TLS 1.2 encryption for all communications within the Amazon Virtual Private Cloud (Amazon VPC). Because sensitive data can exist, enable encryption in transit to help protect that data. | |
| 2.7 | Because sensitive data can exist and to help protect data at transit, ensure encryption is enabled for your Elastic Load Balancing. Use AWS Certificate Manager to manage, provision and deploy public and private SSL/TLS certificates with AWS services and internal resources. | |
| 2.7 | Ensure that your Elastic Load Balancers (ELBs) are configured with SSL or HTTPS listeners. Because sensitive data can exist, enable encryption in transit to help protect that data. | |
| 2.7 | Because sensitive data can exist and to help protect data at rest, ensure encryption is enabled for your Amazon Elastic Block Store (Amazon EBS) volumes. | |
| 2.7 | Ensure that encryption is enabled for your Amazon Relational Database Service (Amazon RDS) snapshots. Because sensitive data can exist at rest, enable encryption at rest to help protect that data. | |
| 2.7 | To help protect data at rest, ensure that encryption is enabled for your Amazon Relational Database Service (Amazon RDS) instances. Because sensitive data can exist at rest in Amazon RDS instances, enable encryption at rest to help protect that data. | |
| 2.7 | To protect data at rest, ensure that encryption is enabled for your Amazon Redshift clusters. You must also ensure that required configurations are deployed on Amazon Redshift clusters. The audit logging should be enabled to provide information about connections and user activities in the database. This rule requires that a value is set for clusterDbEncrypted (Config Default : TRUE), and loggingEnabled (Config Default: TRUE). The actual values should reflect your organization's policies. | |
| 2.7 | Ensure that your Amazon Redshift clusters require TLS/SSL encryption to connect to SQL clients. Because sensitive data can exist, enable encryption in transit to help protect that data. | |

Because sensitive data can exist, enable encryption in transit to help protect that data. | |
| 2.7.1 | Ensure Amazon API Gateway REST API stages are configured with SSL certificates to allow backend systems to authenticate that requests originate from API Gateway. | |
| 2.7.1 | To help protect data in transit, ensure that your Classic Elastic Load Balancing SSL listeners are using a predefined security policy. Elastic Load Balancing provides predefined SSL negotiation configurations that are used for SSL negotiation when a connection is established between a client and your load balancer. The SSL negotiation configurations provide compatibility with a broad range of clients and use high-strength cryptographic algorithms. This rule requires that you set a predefined security policy for your SSL listeners. The default security policy is: ELBSecurityPolicy-TLS-1-2-2017-0. The actual value should reflect your organization's policies | |
| 2.7.2 | Enable key rotation to ensure that keys are rotated after they have reached the end of their crypto period. | |
| 2.7.2 | To help protect data at rest, ensure necessary customer master keys (CMKs) are not scheduled for deletion in AWS Key Management Service (AWS KMS). Because key deletion is necessary at times, this rule can assist in checking for all keys scheduled for deletion, in case a key was scheduled unintentionally. | |
| 2.8.5 | Ensure authentication credentials AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY do not exist within AWS Codebuild project environments. Do not store these variables in clear text. Storing these variables in clear text leads to unintended data exposure and unauthorized access. | |
| 2.8.5 | Ensure the GitHub or Bitbucket source repository URL does not contain personal access tokens, sign-in credentials within AWS Codebuild project environments. Use OAuth instead of personal access tokens or sign-in credentials to grant authorization for accessing GitHub or Bitbucket repositories. | |
| 2.8.6 | Ensure authentication credentials AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY do not exist within AWS Codebuild project environments. Do not store these variables in clear text. Storing these variables in clear text leads to unintended data exposure and unauthorized access. | |
| 2.8.6 | Ensure the GitHub or Bitbucket source repository URL does not contain personal access tokens, sign-in credentials within AWS Codebuild project environments. Use OAuth instead of personal access tokens or sign-in credentials to grant authorization for accessing GitHub or Bitbucket repositories. | |
| 2.9.1 | Centralized management of AWS accounts within AWS Organizations helps to ensure that accounts are compliant. The lack of centralized account governance may lead to inconsistent account configurations, which may expose resources and sensitive data. | |
| 2.9.1 | This rule helps ensure the use of AWS recommended security best practices for AWS CloudTrail, by checking for the enablement of multiple settings. These include the use of log encryption, log validation, and enabling AWS CloudTrail in multiple regions. | |
| 2.9.1 | Utilize AWS CloudTrail log file validation to check the integrity of CloudTrail logs. Log file validation helps determine if a log file was modified or deleted or unchanged after CloudTrail delivered it. This feature is built using industry standard algorithms: SHA-256 for hashing and SHA-256 with RSA for digital signing. This makes it computationally infeasible to modify, delete or forge CloudTrail log files without detection. | |
| 2.9.1 | This rule ensures that Amazon Redshift clusters have the preferred settings for your organization. Specifically, that they have preferred maintenance windows and automated snapshot retention periods for the database. This rule requires you to set the allowVersionUpgrade. The default is true. It also lets you optionally set the preferredMaintenanceWindow (the default is sat:16:00-sat:16:30), and the automatedSnapshotRetentionPeriod (the default is 1). The actual values should reflect your organization's policies. | |
| 2.9.2 | The Elastic Load Balancer (ELB) health checks for Amazon Elastic Compute Cloud (Amazon EC2) Auto Scaling groups support maintenance of adequate capacity and availability. The load balancer periodically sends pings, attempts connections, or sends requests to test Amazon EC2 instances health in an auto-scaling group. If an instance is not reporting back, traffic is sent to a new Amazon EC2 instance. | |
| 2.9.2 | Amazon CloudWatch alarms alert when a metric breaches the threshold for a specified number of evaluation periods. The alarm performs one or more actions based on the value of the metric or expression relative to a threshold over a number of time periods. This rule requires a value for alarmActionRequired (Config Default: True), insufficientDataActionRequired (Config Default: True), okActionRequired (Config Default: False). The actual value should reflect the alarm actions for your environment. | |
| 2.9.2 | Enable this rule to ensure that provisioned throughput capacity is checked on your Amazon DynamoDB tables. This is the amount of read/write activity that each table can support. DynamoDB uses this information to reserve sufficient system resources to meet your throughput requirements. This rule generates an alert when the throughput approaches the maximum limit for a customer's account. This rule allows you to optionally set accountRCUThresholdPercentage (Config Default: 80) and accountWCUThresholdPercentage (Config Default: 80) parameters. The actual values should reflect your organization's policies. | |
| 2.9.2 | Enable this rule to help improve Amazon Elastic Compute Cloud (Amazon EC2) instance monitoring on the Amazon EC2 console, which displays monitoring graphs with a 1-minute period for the instance. | |
| 2.9.2 | This rule ensures that a Lambda function's concurrency high and low limits are established. This can assist in baselining the number of requests that your function is serving at any given time. | |
| 2.9.2 | Enable Amazon Relational Database Service (Amazon RDS) to help monitor Amazon RDS availability. This provides detailed visibility into the health of your Amazon RDS database instances. When the Amazon RDS storage is using more than one underlying physical device, Enhanced Monitoring collects the data for each device. Also, when the Amazon RDS database instance is running in a Multi-AZ deployment, the data for each device on the secondary host is collected, and the secondary host metrics. | |
| 2.9.3 | The backup feature of Amazon RDS creates backups of your databases and transaction logs. Amazon RDS automatically creates a storage volume snapshot of your DB instance, backing up the entire DB instance. The system allows you to set specific retention periods to meet your resilience requirements. | |
| 2.9.3 | Amazon DynamoDB auto scaling uses the AWS Application Auto Scaling service to adjust provisioned throughput capacity that automatically responds to actual traffic patterns. This enables a table or a global secondary index to increase its provisioned read/write capacity to handle sudden increases in traffic, without throttling. | |
| 2.9.3 | To help with data back-up processes, ensure your Amazon DynamoDB tables are a part of an AWS Backup plan. AWS Backup is a fully managed backup service with a policy-based backup solution. This solution simplifies your backup management and enables you to meet your business and regulatory backup compliance requirements. | |
| 2.9.3 | To help with data back-up processes, ensure your Amazon Elastic Block Store (Amazon EBS) volumes are a part of an AWS Backup plan. AWS Backup is a fully managed backup service with a policy-based backup solution. This solution simplifies your backup management and enables you to meet your business and regulatory backup compliance requirements. | |
| 2.9.3 | To help with data back-up processes, ensure your Amazon Elastic File System (Amazon EFS) file systems are a part of an AWS Backup plan. AWS Backup is a fully managed backup service with a policy-based backup solution. This solution simplifies your backup management and enables you to meet your business and regulatory backup compliance requirements. | |
| 2.9.3 | When automatic backups are enabled, Amazon ElastiCache creates a backup of the cluster on a daily basis. The backup can be retained for a number of days as specified by your organization. Automatic backups can help guard against data loss. If a failure occurs, you can create a new cluster, which restores your data from the most recent backup. | |
| 2.9.3 | Enable cross-zone load balancing for your Elastic Load Balancers (ELBs) to help maintain adequate capacity and availability. The cross-zone load balancing reduces the need to maintain equivalent numbers of instances in each enabled availability zone.
