## Key Design Features
|
||||
|
||||
### 1. Idempotency
|
||||
All operations are designed to be safely re-runnable:
|
||||
- API state checking before modifications
|
||||
- `changed_when` conditions on all tasks
|
||||
- Proper handling of create vs. update operations
|
||||
|
||||
### 2. Baseline Import System
|
||||
Unique feature for WAF configuration:
|
||||
- Export WAF config from baseline firewall via API
|
||||
- Transform to structured YAML variables
|
||||
- Commit to version control
|
||||
- Apply as fleet-wide defaults
|
||||
- Allow per-firewall overrides
|
||||
|
||||
### 3. Production-Ready
|
||||
- Ansible Vault support for credentials
|
||||
- Comprehensive error handling
|
||||
- Retry logic for API calls
|
||||
- Timeout configuration
|
||||
- No-log for sensitive data
|
||||
- Serial execution control
|
||||
|
||||
### 4. CI/CD Integration
|
||||
- Check mode for dry-runs
|
||||
- Tagging system for partial deployments
|
||||
- Example GitLab CI configuration
|
||||
- Ansible-lint and yamllint configurations
|
||||
|
||||
### 5. Comprehensive Documentation
|
||||
- README with full usage guide
|
||||
- QUICKSTART for rapid deployment
|
||||
- Inline comments in all playbooks and roles
|
||||
- Example configurations with realistic data
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Deploy Full Configuration
|
||||
```bash
|
||||
ansible-playbook -i inventory/hosts.ini site.yml
|
||||
```
|
||||
|
||||
### Deploy to Specific Firewall
|
||||
```bash
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --limit fw-branch1
|
||||
```
|
||||
|
||||
### Deploy Specific Components
|
||||
```bash
|
||||
# Network only
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --tags network
|
||||
|
||||
# VPN only
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --tags vpn
|
||||
|
||||
# WAF only
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --tags waf
|
||||
```
|
||||
|
||||
### Baseline Import Workflow
|
||||
```bash
|
||||
# 1. Export baseline WAF config
|
||||
ansible-playbook -i inventory/hosts.ini baseline_import.yml
|
||||
|
||||
# 2. Review generated config
|
||||
cat inventory/group_vars/baseline_web.yml
|
||||
|
||||
# 3. Commit to version control
|
||||
git add inventory/group_vars/baseline_web.yml
|
||||
git commit -m "Update baseline WAF configuration"
|
||||
|
||||
# 4. Apply to fleet
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --tags waf
|
||||
```
|
||||
|
||||
### Secure Credentials
|
||||
```bash
|
||||
# Encrypt host variables
|
||||
ansible-vault encrypt inventory/host_vars/fw-branch1.yml
|
||||
|
||||
# Run with vault password
|
||||
ansible-playbook -i inventory/hosts.ini site.yml --ask-vault-pass
|
||||
```
|
||||
|
||||

|
||||
## Deployment Scenarios
|
||||
|
||||
### Scenario 1: New Firewall Fleet
|
||||
1. Define inventory in `hosts.ini`
|
||||
2. Create host_vars for each firewall
|
||||
3. Run full site.yml deployment
|
||||
4. Verify with check mode first
|
||||
|
||||
### Scenario 2: Existing Fleet with WAF
|
||||
1. Define baseline firewall in inventory
|
||||
2. Run baseline_import.yml to export WAF config
|
||||
3. Review and commit baseline_web.yml
|
||||
4. Deploy to remaining firewalls with site.yml
|
||||
|
||||
### Scenario 3: Incremental Updates
|
||||
1. Modify specific variables in host_vars
|
||||
2. Use tags to deploy only changed components
|
||||
3. Use --limit to target specific firewalls
|
||||
4. Review changes with --check first
|
||||
|
||||
### Scenario 4: CI/CD Pipeline
|
||||
1. Commit changes to Git
|
||||
2. CI pipeline validates with ansible-lint
|
||||
3. CI runs check mode for preview
|
||||
4. Manual approval required
|
||||
5. CD applies changes to production
|
||||
|
||||
## API Integration
|
||||
|
||||
### Sophos XGS API
|
||||
- Uses XML-based API via HTTPS
|
||||
- Default port: 4444 (management interface)
|
||||
- Authentication: Username/password or API key
|
||||
- All operations via `uri` Ansible module
|
||||
- XML templates in Jinja2 for all API calls
|
||||
|
||||
### Error Handling
|
||||
- HTTP status code validation
|
||||
- XML response parsing
|
||||
- Retry logic with configurable delays
|
||||
- Timeout protection
|
||||
- Graceful failure modes
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Credentials Management
|
||||
- Ansible Vault integration
|
||||
- No-log for sensitive tasks
|
||||
- Separate credentials per firewall
|
||||
- Support for both password and API key auth
|
||||
|
||||
### Network Security
|
||||
- API access over HTTPS only
|
||||
- Certificate validation (configurable)
|
||||
- Device access policies to restrict management
|
||||
- Rate limiting via serial execution
|
||||
|
||||
### Audit Trail
|
||||
- All changes logged by Sophos XGS
|
||||
- Ansible execution logs
|
||||
- Commit history in Git
|
||||
- CI/CD pipeline logs
|
||||
|
||||
## Maintenance & Support
|
||||
|
||||
### Regular Maintenance Tasks
|
||||
1. Update baseline WAF configuration monthly
|
||||
2. Review firewall logs for errors
|
||||
3. Rotate credentials quarterly
|
||||
4. Update Ansible collections
|
||||
5. Test in lab before production deployment
|
||||
|
||||
### Troubleshooting Resources
|
||||
1. README.md troubleshooting section
|
||||
2. Role task files (detailed comments)
|
||||
3. Template files (show API structure)
|
||||
4. Ansible verbose mode (-vvv)
|
||||
5. Sophos XGS API documentation
|
||||
|
||||
