CC7.1Detection and monitoring for vulnerabilitiesSOC 2System Operations

Official Requirement

To meet its objectives, the entity uses detection and monitoring procedures to identify (1) changes to configurations that result in the introduction of new vulnerabilities, and (2) susceptibilities to newly discovered vulnerabilities.

Source: AICPA Trust Services Criteria (2017), incorporating COSO principles

In Plain English

You have tooling that watches for two things: someone changing a configuration in a way that opens a hole (a rule gets loosened, a port gets opened, a default gets changed), and newly disclosed CVEs that affect software you're already running. This isn't a quarterly scan, auditors expect continuous or near-continuous detection with a documented remediation SLA.

On-premises implementation and evidence

Continuous vulnerability scanning with SLA-driven remediation

Implementation steps

  1. Install vulnerability/configuration management agents on all production servers; enable the vulnerability detection module to scan installed packages against the NVD CVE feed
  2. Run periodic DAST scans (OWASP ZAP, Nikto) against internally hosted web applications to identify runtime vulnerabilities such as injection flaws, broken authentication, and server misconfigurations
  3. For network appliances that cannot run agents (firewall appliance, switches), subscribe to vendor security advisories and log advisory reviews as work orders
  4. Set up alerts for critical findings so the responsible team is notified and can action within 24 hours
  5. Track all findings in a vulnerability register (a spreadsheet or your GRC platform) with discovery date, severity, assigned owner, and closure date

Evidence artifacts

Evidence frequency: Weekly scans; vulnerability register updated at each finding; quarterly review of open items

Configuration drift detection and baseline enforcement

Implementation steps

  1. Enable your SIEM/monitoring platform file integrity monitoring (FIM) on critical configuration files: /etc, sshd_config, firewall rules, IIS config, any change triggers an alert
  2. Use Ansible playbooks to define desired configuration state; run Ansible in check mode weekly to detect drift from baseline
  3. Log all firewall rule changes in a change log with before/after state; the ISM must review and approve any firewall modification before implementation
  4. Set a quarterly CIS benchmark run via your SIEM/monitoring platform to score production servers against the approved baseline and document the score delta
