Why Vulnerability Management is Core Security
Unpatched vulnerabilities are still the #1 root cause of breaches. OpenVAS provides an open-source equivalent to Nessus/Qualys for vulnerability scanning.
Deployment Checklist
- Install Greenbone Community Edition.
- Run authenticated scans (SSH/WinRM creds).
- Integrate with patch management (Ansible playbooks).
- Schedule monthly full scans; weekly delta scans.
- Track remediation progress with reporting.
Applied Example
- Scanned Linux NUC: flagged outdated Apache with CVE.
- Ansible playbook patched and re-scanned → clean result.
Why Clients Care
- Evidence for auditors.
- Proves proactive vulnerability management.
- CISO dashboard: measurable “risk reduced per month”.
