CfnAccountPolicy
- class aws_cdk.aws_logs.CfnAccountPolicy(scope_, id, *, policy_document, policy_name, policy_type, scope=None, selection_criteria=None)
Bases:
CfnResource
Creates or updates an account-level data protection policy or subscription filter policy that applies to all log groups or a subset of log groups in the account.
Data protection policy
A data protection policy can help safeguard sensitive data that’s ingested by your log groups by auditing and masking the sensitive log data. Each account can have only one account-level data protection policy. .. epigraph:
Sensitive data is detected and masked when it is ingested into a log group. When you set a data protection policy, log events ingested into the log groups before that time are not masked.
If you create a data protection policy for your whole account, it applies to both existing log groups and all log groups that are created later in this account. The account policy is applied to existing log groups with eventual consistency. It might take up to 5 minutes before sensitive data in existing log groups begins to be masked.
By default, when a user views a log event that includes masked data, the sensitive data is replaced by asterisks. A user who has the
logs:Unmask
permission can use a GetLogEvents or FilterLogEvents operation with theunmask
parameter set totrue
to view the unmasked log events. Users with thelogs:Unmask
can also view unmasked data in the CloudWatch Logs console by running a CloudWatch Logs Insights query with theunmask
query command.For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking .
To create an account-level policy, you must be signed on with the
logs:PutDataProtectionPolicy
andlogs:PutAccountPolicy
permissions.An account-level policy applies to all log groups in the account. You can also create a data protection policy that applies to just one log group. If a log group has its own data protection policy and the account also has an account-level data protection policy, then the two policies are cumulative. Any sensitive term specified in either policy is masked.
Subscription filter policy
A subscription filter policy sets up a real-time feed of log events from CloudWatch Logs to other AWS services. Account-level subscription filter policies apply to both existing log groups and log groups that are created later in this account. Supported destinations are Kinesis Data Streams , Firehose , and Lambda . When log events are sent to the receiving service, they are Base64 encoded and compressed with the GZIP format.
The following destinations are supported for subscription filters:
An Kinesis Data Streams data stream in the same account as the subscription policy, for same-account delivery.
An Firehose data stream in the same account as the subscription policy, for same-account delivery.
A Lambda function in the same account as the subscription policy, for same-account delivery.
A logical destination in a different account created with PutDestination , for cross-account delivery. Kinesis Data Streams and Firehose are supported as logical destinations.
Each account can have one account-level subscription filter policy. If you are updating an existing filter, you must specify the correct name in
PolicyName
. To perform aPutAccountPolicy
subscription filter operation for any destination except a Lambda function, you must also have theiam:PassRole
permission.- See:

- CloudformationResource:
AWS::Logs::AccountPolicy
- ExampleMetadata:
fixture=_generated
Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. from aws_cdk import aws_logs as logs cfn_account_policy = logs.CfnAccountPolicy(self, "MyCfnAccountPolicy", policy_document="policyDocument", policy_name="policyName", policy_type="policyType", # the properties below are optional scope="scope", selection_criteria="selectionCriteria" )
- Parameters:
scope (
Optional
[str
]) – Scope in which this resource is defined.id (
str
) – Construct identifier for this resource (unique in its scope).policy_document (
str
) –Specify the policy, in JSON. Data protection policy A data protection policy must include two JSON blocks: - The first block must include both a
DataIdentifer
array and anOperation
property with anAudit
action. TheDataIdentifer
array lists the types of sensitive data that you want to mask. For more information about the available options, see Types of data that you can mask . TheOperation
property with anAudit
action is required to find the sensitive data terms. ThisAudit
action must contain aFindingsDestination
object. You can optionally use thatFindingsDestination
object to list one or more destinations to send audit findings to. If you specify destinations such as log groups, Firehose streams, and S3 buckets, they must already exist. - The second block must include both aDataIdentifer
array and anOperation
property with anDeidentify
action. TheDataIdentifer
array must exactly match theDataIdentifer
array in the first block of the policy. TheOperation
property with theDeidentify
action is what actually masks the data, and it must contain the"MaskConfig": {}
object. The"MaskConfig": {}
object must be empty. .. epigraph:: The contents of the twoDataIdentifer
arrays must match exactly. In addition to the two JSON blocks, thepolicyDocument
can also includeName
,Description
, andVersion
fields. TheName
is different than the operation’spolicyName
parameter, and is used as a dimension when CloudWatch Logs reports audit findings metrics to CloudWatch . The JSON specified inpolicyDocument
can be up to 30,720 characters long. Subscription filter policy A subscription filter policy can include the following attributes in a JSON block: - DestinationArn The ARN of the destination to deliver log events to. Supported destinations are: - An Kinesis Data Streams data stream in the same account as the subscription policy, for same-account delivery. - An Firehose data stream in the same account as the subscription policy, for same-account delivery. - A Lambda function in the same account as the subscription policy, for same-account delivery. - A logical destination in a different account created with PutDestination , for cross-account delivery. Kinesis Data Streams and Firehose are supported as logical destinations. - RoleArn The ARN of an IAM role that grants CloudWatch Logs permissions to deliver ingested log events to the destination stream. You don’t need to provide the ARN when you are working with a logical destination for cross-account delivery. - FilterPattern A filter pattern for subscribing to a filtered stream of log events. - Distribution The method used to distribute log data to the destination. By default, log data is grouped by log stream, but the grouping can be set toRandom
for a more even distribution. This property is only applicable when the destination is an Kinesis Data Streams data stream.policy_name (
str
) – A name for the policy. This must be unique within the account.policy_type (
str
) – The type of policy that you’re creating or updating.scope – Currently the only valid value for this parameter is
ALL
, which specifies that the policy applies to all log groups in the account. If you omit this parameter, the default ofALL
is used. To scope down a subscription filter policy to a subset of log groups, use theselectionCriteria
parameter.selection_criteria (
Optional
[str
]) – Use this parameter to apply a subscription filter policy to a subset of log groups in the account. Currently, the only supported filter isLogGroupName NOT IN []
. TheselectionCriteria
string can be up to 25KB in length. The length is determined by using its UTF-8 bytes. Using theselectionCriteria
parameter is useful to help prevent infinite loops. For more information, see Log recursion prevention . SpecifingselectionCriteria
is valid only when you specifySUBSCRIPTION_FILTER_POLICY
forpolicyType
.
Methods
- add_deletion_override(path)
Syntactic sugar for
addOverride(path, undefined)
.- Parameters:
path (
str
) – The path of the value to delete.- Return type:
None
- add_dependency(target)
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
- Parameters:
target (
CfnResource
) –- Return type:
None
- add_depends_on(target)
(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
- Parameters:
target (
CfnResource
) –- Deprecated:
use addDependency
- Stability:
deprecated
- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –value (
Any
) –
- See:
- Return type:
None
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
with “Properties.” (i.e.Properties.TopicName
).If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal
.
in the property name, prefix with a\
. In most programming languages you will need to write this as"\\."
because the\
itself will need to be escaped.For example:
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")
would add the overrides Example:
"Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... }
The
value
argument toaddOverride
will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
path (
str
) –The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (
Any
) –The value. Could be primitive or complex.
- Return type:
None
- add_property_deletion_override(property_path)
Adds an override that deletes the value of a property from the resource definition.
- Parameters:
property_path (
str
) – The path to the property.- Return type:
None
- add_property_override(property_path, value)
Adds an override to a resource property.
Syntactic sugar for
addOverride("Properties.<...>", value)
.- Parameters:
property_path (
str
) – The path of the property.value (
Any
) – The value.
- Return type:
None
- apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY
), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN
). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT
). A list of resources that support this policy can be found in the following link:- Parameters:
policy (
Optional
[RemovalPolicy
]) –apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
Optional
[RemovalPolicy
]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.
- See:
- Return type:
None
- get_att(attribute_name, type_hint=None)
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g.
resource.arn
), but this can be used for future compatibility in case there is no generated attribute.- Parameters:
attribute_name (
str
) – The name of the attribute.type_hint (
Optional
[ResolutionTypeHint
]) –
- Return type:
- get_metadata(key)

- stack
The stack in which this element is defined.
CfnElements must be defined within a stack scope (directly or indirectly).
Static Methods
- classmethod is_cfn_element(x)
Returns
true
if a construct is a stack element (i.e. part of the synthesized cloudformation template).Uses duck-typing instead of
instanceof
to allow stack elements from different versions of this library to be included in the same stack.- Parameters:
x (
Any
) –- Return type:
bool
- Returns:
The construct as a stack element or undefined if it is not a stack element.
- classmethod is_cfn_resource(x)
Check whether the given object is a CfnResource.
- Parameters:
x (
Any
) –- Return type:
bool
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
