• Syslog server configuration
• NTP time synchronization

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

ansible-playbook -i inventory/hosts.ini site.yml

Deploy to Specific Firewall

ansible-playbook -i inventory/hosts.ini site.yml --limit fw-branch1

Deploy Specific Components

# 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

# 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

# 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

Variable Schema

Complete variable documentation available in separate schema document. Key variable types:

• Network: sophos_interfaces, sophos_vlans, sophos_dhcp_servers, sophos_dns, sophos_static_routes
• Firewall: sophos_firewall_rules, sophos_common_firewall_rules
• VPN: sophos_site_to_site_vpns, sophos_remote_access_vpn
• WAF: sophos_waf_backends, sophos_waf_policies, sophos_waf_virtual_hosts, sophos_waf_exceptions
• Management: sophos_common_device_access_policies, sophos_snmp, sophos_logging, sophos_ntp

Testing & Quality

Linting

• ansible-lint configuration included
• yamllint configuration included
• Skips appropriate false-positives

Sample Configurations

• fw-baseline: Baseline firewall with DMZ
• fw-branch1: Branch with site-to-site VPN, VLANs, DHCP options
• fw-branch2: Branch with remote access VPN
• fw-sample1: Minimal test configuration

Validation

• Pre-flight connectivity checks
• Required variable validation
• API authentication testing
• Firmware version compatibility warnings

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

• SD-WAN configuration
• Application control policies
• IPS signature management
• Certificate management
• User authentication (LDAP/RADIUS)
• High availability (HA) configuration
• Backup and restore automation
• Custom report generation
