Simplify management of security groups with security group rule descriptions

Amazon EC2 now allows customers to add a short description to individual security group rules. Using this functionality, customers can add details like when and why a certain security group rule was created or updated. This functionality simplifies management of security groups as customers no longer need to track this information using spreadsheets or documents.

This capability is available in all AWS regions and is supported by both AWS VPC and AWS EC2-Classic Security groups. For more information about security group rules, visit the security group rules page for EC2-VPC and the security group rules page for EC2-Classic.
