# Implementing Secure Session Management

## Overview

Build secure sessions with proper token generation, storage, expiration, and invalidation.

## Prerequisites

| Requirement | Install |
|---|---|
| Framework session lib | Flask-Session |
| Redis | Session store |
| Python 3.10+ | For agent tooling |

## Key Concepts

Secure sessions require random tokens, HTTPOnly/Secure/SameSite
cookies, server-side storage, proper expiration, and invalidation.

## Quick Reference

```bash
node agent.js audit --file session.py --checks token,cookie,expiry
node agent.js test --url https://target.com --checks session-fixation
node agent.js generate --component session --store redis
node agent.js report --directory src/
```

## Workflow

1. Random tokens
2. Cookie flags
3. Server-side storage
4. Set timeouts
5. Invalidate on logout
6. Regenerate on privilege change
7. Test fixation

## Verification

- Random tokens
- Cookie flags set
- Expiration works
- Logout invalidation
- Token regeneration
