5.6 Ensure Monitoring and Logging is Enabled

Description

Implementing monitoring and logging for Amazon ElastiCache allows you to gain visibility into the performance, health, and behavior of your ElastiCache clusters.

Rationale

This helps the individual know what is being logged within the activity and determine what next step they should take to address any suspicious activity.

Impact

If the individual is not monitoring and logging their activity it allows the attacker to attack the system and extract or destroy data.

Audit Procedure

Using AWS Console

Sign in to the AWS Management Console
- Sign in to the AWS Management Console at https://console.aws.amazon.com/ with your AWS account credentials.
Open the ElastiCache Console
- Navigate to the service using the Find Services search bar or by directly accessing the console at https://console.aws.amazon.com/elasticache/.
Select the ElastiCache Cluster
- Choose the ElastiCache cluster for which you want to implement monitoring and logging.
- Click on the cluster name to access its details page.
Enable Enhanced Monitoring
- Click on the Monitoring tab on the cluster details page.
- Under the Monitoring section, click on the Enable Enhanced Monitoring button.
- Select the desired monitoring granularity (1 minute, 5 minutes, or 60 minutes) to capture detailed metrics.
- Choose the desired CloudWatch namespace to store the metrics.
- Click Save changes to enable enhanced monitoring for the ElastiCache cluster.
Set Up CloudWatch Alarms
- In the CloudWatch console, navigate to Alarms in the left-side menu.
- Click Create alarm to create a new alarm.
- Select the appropriate ElastiCache metrics from the available options.
- Configure the threshold, conditions, and actions for the alarm.
- Choose the actions to take when the alarm state is triggered (e.g., send notifications, auto-scaling actions, etc.).
- Click Create alarm to save the alarm configuration.
Configure CloudWatch Logs
- In the CloudWatch console, navigate to Logs in the left-side menu.
- Click Create log group to create a new one.
- Provide a unique name for the log group and optionally specify a retention period for log data.
- Click Create log group to create the log group.
- On the ElastiCache cluster details page, click the Logging tab.
- Enable the CloudWatch Logs option and select the desired log group from the dropdown menu.
- Click Save changes to enable CloudWatch Logs for the ElastiCache cluster.
Verify Monitoring and Logging
- Wait a few minutes for the monitoring and logging configurations to take effect.
- Refresh the cluster details page for the updated monitoring and logging status.
- Navigate to the CloudWatch console to view metrics, alarms, and logs related to your ElastiCache cluster.

Expected Result

Enhanced monitoring is enabled, CloudWatch alarms are configured, and CloudWatch Logs are enabled for all ElastiCache clusters.

Remediation

The individual can understand the health, performance, and behavior of their clusters which allows them to address any unusual activity that takes place.

Using AWS Console

Follow the same steps as the audit procedure to enable monitoring and logging for ElastiCache clusters.

Default Value

By default, basic monitoring is enabled but enhanced monitoring and CloudWatch Logs require manual configuration.
