+**Bakery IA Platform - Consolidated Security Guides**
+
+---
+
+## Overview
+
+This directory contains comprehensive, production-ready security documentation for the Bakery IA platform. Our infrastructure has been hardened from a **D- security grade to an A- grade** through systematic implementation of industry best practices.
+

+- **Compliance ready** for GDPR, PCI-DSS, and SOC 2
+
+### Security Grade Improvement
+
+| Metric | Before | After |
+|--------|--------|-------|
+| Overall Grade | D- | A- |

+
+## Quick Start
+
+### For Developers
+
+1. **Authentication**: All services use JWT tokens
+2. **Authorization**: Use role decorators from `shared/auth/access_control.py`
+3. **Database**: Connections automatically use TLS
+4. **Secrets**: Never commit credentials - use Kubernetes secrets
+
+### For Operations
+
+1. **TLS Certificates**: Stored in `infrastructure/tls/`
+2. **Backup Script**: `scripts/encrypted-backup.sh`
+3. **Password Rotation**: `scripts/generate-passwords.sh`
+4. **Monitoring**: Check audit logs regularly
+

+## Common Security Tasks
+
+### Rotate Database Passwords
+
+```bash
+# Generate new passwords
+./scripts/generate-passwords.sh
+
+# Update environment files
+./scripts/update-env-passwords.sh
+
+# Update Kubernetes secrets
+./scripts/update-k8s-secrets.sh
+```
+
+### Create Encrypted Backup
+
+```bash
+# Backup all databases
+./scripts/encrypted-backup.sh
+
+# Restore specific database
+gpg --decrypt backup_file.sql.gz.gpg | gunzip | psql -U user -d database
+```
+
+### Regenerate TLS Certificates
+
+```bash
+# Regenerate all certificates (before expiry)
+cd infrastructure/tls
+./generate-certificates.sh
+
+# Update Kubernetes secrets
+./scripts/create-tls-secrets.sh
+```
+
+## Security Best Practices
+
+### For Developers
+
+1. **Never hardcode credentials** - Use environment variables
+2. **Always use role decorators** on sensitive endpoints
+3. **Validate input** - Prevent SQL injection and XSS
+4. **Log security events** - Failed auth, permission denied
+5. **Use parameterized queries** - Never concatenate SQL
+6. **Implement rate limiting** - Prevent brute force attacks
+
+### For Operations
+
+1. **Rotate passwords regularly** - Every 90 days
+2. **Monitor audit logs** - Check for suspicious activity
+3. **Keep certificates current** - Renew before expiry
+4. **Test backups** - Verify restoration procedures
+5. **Update dependencies** - Apply security patches
+6. **Review access** - Remove unused accounts
+
+## Incident Response
+
+### Security Incident Checklist
+
+1. **Identify** the scope and impact
+2. **Contain** the threat (disable compromised accounts)
+3. **Eradicate** the vulnerability
+4. **Recover** affected systems
+5. **Document** the incident
+6. **Review** and improve security measures
+
+### Emergency Contacts
+
+- Security incidents should be reported immediately
+- Check audit logs: `/var/log/postgresql/` in database pods
+- Review application logs for suspicious patterns
