cdk-aspects-library-security-group

build

A CDK library containing EC2 security group related CDK Aspects and the ability to define custom aspects.

Features

  • Utilize built in aspects for common cases:
    • Disallow public access to any port
    • Disallow public access to AWS Restricted Common ports (per the AWS Config rule)
    • Disallow public access to SSH or RDP per CIS Benchmark guidelines and general good practice
    • Disallow public or ALL access to common management ports like SSH, RDP, WinRM, WinRM over HTTPS
    • Disallow public or ALL access common relational DB ports like MSSQL, MySQL, PostgreSQL, and Oracle
    • Disallow public or ALL common web ports like HTTP (80, 8080) and HTTPS (443, 8443)
  • Create any other aspect using the base security group aspect class.
  • By default aspects generate errors in the CDK metadata which the deployment or synth process will find, but this can be changed with the annotationType property
  • All default provided aspects restrict based on the public access CIDRs (0.0.0.0/0 and ::/0) but you can also defined aspects with any set of restricted CIDRs or security group IDs you like
