Audits AWS security groups to identify overly permissive rules and improve network security posture.
The AWS Security Group Analyzer is a specialized tool designed to evaluate and harden your AWS network security by scanning for vulnerabilities in EC2 security groups. It helps engineers identify high-risk configurations—such as SSH, RDP, or database ports open to the public internet (0.0.0.0/0)—and provides actionable AWS CLI commands to restrict access based on the principle of least privilege. Whether you are performing a routine security audit, cleaning up unused resources, or implementing a multi-tier architecture, this skill streamlines the process of securing your cloud infrastructure through automated checks and guided remediation patterns.
