description: |
|
|
Ensures Amazon VPC Flow Logs are enabled for tracking network traffic to and from VPCs, aiding in security and troubleshooting.
|
|
impact: |
|
|
Without VPC Flow Logs, detecting abnormal traffic patterns or breaches becomes difficult, increasing risk of undetected threats.
|
|
remediation: |
|
|
Enable VPC Flow Logs in the AWS Management Console under the VPC dashboard to collect data on IP traffic going to and from network interfaces in your VPC.
