A remediation exception is when a specified resource is no longer considered for auto-remediation. This API adds a new exception or updates an existing exception for a specified resource with a specified Config rule.
Exceptions block auto remediation Config generates a remediation exception when a problem occurs running a remediation action for a specified resource. Remediation exceptions blocks auto-remediation until the exception is cleared.
Manual remediation is recommended when placing an exception When placing an exception on an Amazon Web Services resource, it is recommended that remediation is set as manual remediation until the given Config rule for the specified resource evaluates the resource as
NON_COMPLIANT. Once the resource has been evaluated as
NON_COMPLIANT, you can add remediation exceptions and change the remediation type back from Manual to Auto if you want to use auto-remediation. Otherwise, using auto-remediation before a
NON_COMPLIANT evaluation result can delete resources before the exception is applied.
Exceptions can only be performed on non-compliant resources Placing an exception can only be performed on resources that are
NON_COMPLIANT. If you use this API for
COMPLIANT resources or resources that are
NOT_APPLICABLE, a remediation exception will not be generated. For more information on the conditions that initiate the possible Config evaluation results, see
Concepts | Config Rules in the
Config Developer Guide.
Auto remediation can be initiated even for compliant resources If you enable auto remediation for a specific Config rule using the
PutRemediationConfigurations API or the Config console, it initiates the remediation process for all non-compliant resources for that specific rule. The auto remediation process relies on the compliance data snapshot which is captured on a periodic basis. Any non-compliant resource that is updated between the snapshot schedule will continue to be remediated based on the last known compliance data snapshot.
This means that in some cases auto remediation can be initiated even for compliant resources, since the bootstrap processor uses a database that can have stale evaluation results based on the last known compliance data snapshot.
