Associate Kms Key
cloudwatchlogs_associate_kms_key | R Documentation |
Associates the specified KMS key with either one log group in the account, or with all stored CloudWatch Logs query insights results in the account¶
Description¶
Associates the specified KMS key with either one log group in the account, or with all stored CloudWatch Logs query insights results in the account.
When you use associate_kms_key
, you specify either the logGroupName
parameter or the resourceIdentifier
parameter. You can't specify both
of those parameters in the same operation.
-
Specify the
logGroupName
parameter to cause all log events stored in the log group to be encrypted with that key. Only the log events ingested after the key is associated are encrypted with that key.Associating a KMS key with a log group overrides any existing associations between the log group and a KMS key. After a KMS key is associated with a log group, all newly ingested data for the log group is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
Associating a key with a log group does not cause the results of queries of that log group to be encrypted with that key. To have query results encrypted with a KMS key, you must use an
associate_kms_key
operation with theresourceIdentifier
parameter that specifies aquery-result
resource. -
Specify the
resourceIdentifier
parameter with aquery-result
resource, to use that key to encrypt the stored results of all futurestart_query
operations in the account. The response from aget_query_results
operation will still return the query results in plain text.Even if you have not associated a key with your query results, the query results are encrypted when stored, using the default CloudWatch Logs method.
If you run a query from a monitoring account that queries logs in a source account, the query results key from the monitoring account, if any, is used.
If you delete the key that is used to encrypt log events or log group query results, then all the associated stored log events or query results that were encrypted with that key will be unencryptable and unusable.
CloudWatch Logs supports only symmetric KMS keys. Do not use an associate an asymmetric KMS key with your log group or query results. For more information, see Using Symmetric and Asymmetric Keys.
It can take up to 5 minutes for this operation to take effect.
If you attempt to associate a KMS key with a log group but the KMS key
does not exist or the KMS key is disabled, you receive an
InvalidParameterException
error.
Usage¶
Arguments¶
logGroupName
The name of the log group.
In your
associate_kms_key
operation, you must specify either theresourceIdentifier
parameter or thelogGroup
parameter, but you can't specify both.kmsKeyId
[required] The Amazon Resource Name (ARN) of the KMS key to use when encrypting log data. This must be a symmetric KMS key. For more information, see Amazon Resource Names and Using Symmetric and Asymmetric Keys.
resourceIdentifier
Specifies the target for this operation. You must specify one of the following:
Specify the following ARN to have future
get_query_results
operations in this account encrypt the results with the specified KMS key. Replace REGION and ACCOUNT_ID with your Region and account ID.arn:aws:logs:REGION:ACCOUNT_ID:query-result:*
Specify the ARN of a log group to have CloudWatch Logs use the KMS key to encrypt log events that are ingested and stored by that log group. The log group ARN must be in the following format. Replace REGION and ACCOUNT_ID with your Region and account ID.
arn:aws:logs:REGION:ACCOUNT_ID:log-group:LOG_GROUP_NAME
In your
associate_kms_key
operation, you must specify either theresourceIdentifier
parameter or thelogGroup
parameter, but you can't specify both.
Value¶
An empty list.
