# Implementing Privacy Aware Logging

## Overview
Implement log sanitization and PII redaction to prevent privacy violations in application and infrastructure logs.

## Prerequisites

| Requirement | Details |
|---|---|
| Python 3.10+ | Required |
| Access to log infrastructure | Required |

## Key Concepts
1. **PII Detection** — Identify sensitive data patterns in logs
2. **Redaction** — Apply masking/tokenization to PII fields
3. **Validation** — Verify sanitized output retains utility

## Workflow
```bash
node scripts/agent.js analyze --target /var/log/app.log
node scripts/agent.js redact --target /var/log/app.log --output sanitized.log
```

## Verification
- [ ] PII patterns detected
- [ ] Redaction applied correctly
- [ ] Log utility preserved
