# Workflows - Palo Alto NGFW Implementation

## Deployment Workflow

```
Phase 1: Planning
├── Document network topology and traffic flows
├── Define security zones and trust levels
├── Inventory applications and required access
├── Plan IP addressing and interface assignments
└── Define decryption policy scope and exclusions

Phase 2: Base Configuration
├── Configure management interface and system settings
├── Set up HA pair (active/passive)
├── Configure network interfaces and zones
├── Set up Zone Protection profiles
├── Configure routing (static or dynamic)
└── Integrate with DNS, NTP, LDAP/AD

Phase 3: Security Policy Development
├── Create Security Profile Groups (AV, AS, VP, URL, FB, WF)
├── Build application-based Security Policies
├── Configure SSL Decryption policies
├── Set up User-ID integration with AD
├── Create NAT policies
└── Configure DoS Protection policies

Phase 4: Logging and Monitoring
├── Configure Syslog/SIEM forwarding
├── Set up log forwarding profiles
├── Configure SNMP monitoring
├── Enable Cortex Data Lake integration
└── Create custom reports and dashboards

Phase 5: Testing and Validation
├── Validate application classification with Policy Optimizer
├── Test threat prevention with EICAR and test URLs
├── Verify SSL decryption certificate chain
├── Conduct penetration test against firewall
├── Review and remediate audit findings
└── Document final configuration baseline

Phase 6: Operations
├── Schedule automatic content updates
├── Monitor threat and traffic dashboards
├── Review Security Policy rule hit counts monthly
├── Conduct quarterly firewall rule review
├── Test HA failover quarterly
└── Upgrade PAN-OS per vendor schedule
```

## Change Management Workflow

```
1. Submit change request with business justification
2. Review impact analysis (affected zones, applications, users)
3. Approve through CAB (Change Advisory Board)
4. Clone current configuration as backup
5. Implement change in maintenance window
6. Validate with `validate full` before commit
7. Commit changes and monitor logs for 24 hours
8. Document changes in configuration management database
```
