Question 1

Is cloudwatch_log_group_kms_key_id enforced for NIST SP 800-53 Rev 5?

Accepted Answer

Yes, This control checks whether a CloudWatch Logs log group is associated with an AWS KMS key. CloudWatch Logs always encrypts log data at rest with a service-owned key; the control passes only if the log group has a KMS key configured and fails otherwise.

Question 2

Is cloudwatch_log_group_retention_in_days enforced for NIST SP 800-53 Rev 5?

Accepted Answer

Yes, Ensure a minimum duration of event log data is retained for your log groups to help with troubleshooting and forensics investigations.

Question 3

Is cluster_monitoring_interval enforced for NIST SP 800-53 Rev 5?

Accepted Answer

Yes, Enable AWS Relational Database Service (AWS RDS) to help monitor AWS RDS availability. This provides detailed visibility into the health of your AWS RDS database instances.

Question 4

Is deletion_protection enforced for NIST SP 800-53 Rev 5?

Accepted Answer

Yes, This control checks whether RDS clusters have deletion protection enabled. This control is intended for RDS DB instances. However, it can also generate findings for Aurora DB instances, Neptune DB instances, and AWS DocumentDB clusters. If these findings are not useful,then you can suppress them.
