Synopsis

Calls the Amazon CloudWatch Logs AssociateKmsKey API operation.

Syntax

Register-CWLKmsKey
-KmsKeyId <String>
-LogGroupName <String>
-ResourceIdentifier <String>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>
-ClientConfig <AmazonCloudWatchLogsConfig>

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 AssociateKmsKey, 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 AssociateKmsKey operation with the resourceIdentifier parameter that specifies a query-result resource.
  • Specify the resourceIdentifier parameter with a query-result resource, to use that key to encrypt the stored results of all future StartQuery operations in the account. The response from a GetQueryResults 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.

Parameters

-ClientConfig <AmazonCloudWatchLogsConfig>
Amazon.PowerShell.Cmdlets.CWL.AmazonCloudWatchLogsClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-KmsKeyId <String>
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.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-LogGroupName <String>
The name of the log group.In your AssociateKmsKey operation, you must specify either the resourceIdentifier parameter or the logGroup parameter, but you can't specify both.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the KmsKeyId parameter. The -PassThru parameter is deprecated, use -Select '^KmsKeyId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ResourceIdentifier <String>
Specifies the target for this operation. You must specify one of the following:
  • Specify the following ARN to have future GetQueryResults 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 AssociateKmsKey operation, you must specify either the resourceIdentifier parameter or the logGroup parameter, but you can't specify both.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The cmdlet doesn't have a return value by default. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatchLogs.Model.AssociateKmsKeyResponse). Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
