6.4 Ensure Audit Logging is Enabled (Manual)

Description

Enabling audit logging on Amazon MemoryDB allows you to capture and store logs of activities performed on your clusters.

Rationale

It captures and saves logs of activities that took place in the cluster.

Impact

Reduces risks of any fraud since worker activity is being monitored and tracked.

Audit Procedure

Using AWS Console

1. Sign into the AWS Management Console

   • Sign into the AWS Management Console at https://console.aws.amazon.com/ with your AWS account credentials.

2. Open the Amazon MemoryDB Console

   • Navigate to the service using the Find Services search bar or by directly accessing the console at https://console.aws.amazon.com/memorydb/.

3. Select the Cluster

   • Choose the MemoryDB cluster for which you want to enable audit logging. Click on the cluster name to access its details page.

4. Enable Amazon CloudWatch Logs

   • In the cluster details page, navigate to the Logging section.
   • Click on Modify to edit the logging settings.
   • Select the option to enable CloudWatch Logs.
   • Choose an existing CloudWatch log group or create a new one to store the logs generated by the MemoryDB cluster activities.
   • Optionally, you can specify a log retention period to define how long the logs will be stored.
   • Click Apply Changes to enable CloudWatch Logs for the MemoryDB cluster.

5. Configure CloudWatch Logs

   • Open the CloudWatch console by navigating to CloudWatch in the AWS Management Console.
   • In the left-side menu, click on Logs.
   • Create a new log group or select an existing log group that will store the MemoryDB logs.
   • Configure log retention settings based on your retention requirements. Logs can be stored for a specific number of days or indefinitely.
   • Define any necessary log group permissions to control access to the logs.
   • Optionally, set up log exports or alarms for specific log events or patterns if needed.

6. Verify Logging Status

   • Wait a few minutes for the changes to propagate and the logging configuration to take effect.
   • Refresh the cluster details page to see the updated logging status.
   • Verify that CloudWatch Logs is enabled for the MemoryDB cluster.

7. Monitor and Analyze Logs

   • Navigate to the CloudWatch console and select the log group that stores the MemoryDB logs.
   • Monitor the logs to gain insights into the activities and operations performed on your MemoryDB cluster.
   • Use CloudWatch Logs features, such as log searching, filtering, and visualization, to analyze the logs and identify any security or operational issues.
   • Establish appropriate log monitoring and alerting mechanisms to proactively identify and respond to potential security incidents or operational anomalies.

Expected Result

CloudWatch Logs is enabled for all MemoryDB clusters with appropriate log groups and retention periods configured.

Remediation

Using AWS Console

Follow the audit procedure steps to enable CloudWatch Logs for each MemoryDB cluster and configure appropriate log retention and monitoring.

Default Value

Audit logging is not enabled by default for Amazon MemoryDB for Redis.
