DNS Server and Router Config

• Store DNS entries as code (Git commit + push)
• Apply DNS updates automatically from git (Git clone + SSH/scp)
• Apply router configuration in GUI
• Backup router configuration as code (SSH/scp + Git commit + push)

Maintain a Device Inventory

• Physical workstations, servers, routers, network devices
• Virtual machines, containers
• Source of truth inventory (Ansible or Netbox)
• Scan environment (nmap, Nessus or similar)
• MAC address, IP, hostname, ports open

Continuous Integration

• Build
• Run unit tests including adding regression tests when issues are found
• Run unit tests with Address Sanitizer and Thread Sanitizer etc.
• Lint (C++, bash, docker files, ansible)
• Static Analysis
• Fuzzing
• Secret scanning (Passwords, API keys, private keys)
• Vulnerability Assessment (Check package dependencies for vulnerabilities for that version)
• Package including signatures
• Store artifacts (Nexus, Apache, RPM/DEB package manager, ftp, git lfs, Docker, etc.)

Continuous Deployment

• Deploy (Ansible, SSH, etc.)
• Application/Server Health Checks (ping, do requests, check status pages, check logging)
• Basic configuration testing (nmap, check SSL allowed ciphers, and certificates, security headers, cookie settings)
• Basic vulnerability Scanning (metasploit, Nessus)
• Push Traffic/Run Process and Check Outcome
• Push corrupt/malicious traffic, fuzz test across network
• Push high volumes of traffic to saturate the network connection
• Test session cookie stealing doesn't work (The user should not be able to take a cookie from one IP and use it on another IP to steal the session, check that a log is generated)
• Spam actions to test rate limiting (Logins, adding/updating/deleting records, check that logs are generated to warn about this behaviour, then rate limiting occurs, then temporary bans, then permanent bans occur)
• Pen test
