Checking Session Security

Overview

This skill provides automated assistance for the described functionality.

Prerequisites

Before using this skill, ensure:

• Source code accessible in {baseDir}/
• Session management code locations known (auth modules, middleware)
• Framework information (Express, Django, Spring, etc.)
• Configuration files for session settings
• Write permissions for security report in {baseDir}/security-reports/

Instructions

1. Review session creation, storage, and transport security controls.
2. Validate cookie flags, rotation, expiration, and invalidation behavior.
3. Identify common attack paths (fixation, CSRF, replay) and mitigations.
4. Provide prioritized fixes with configuration/code examples.

See {baseDir}/references/implementation.md for detailed implementation guide.

Output

The skill produces:

Primary Output: Session security report saved to {baseDir}/security-reports/session-security-YYYYMMDD.md

Report Structure:
