Impact

ELBv2 provide access logs that capture information about the TLS requests sent to NLBs. These access logs can be used to analyze traffic patterns and troubleshoot security and operational issues. Access logging is an optional feature of ELB that is disabled by default. There is no additional charge for access logs. You are charged storage costs for Amazon S3, but not charged for the bandwidth. After you enable access logging for your load balancer, ELBv2 captures the logs as compressed files and stores them in the Amazon S3 bucket that you specify.

How to Fix

• • Key: access_logs.s3.enabled
• Value: "true"
