SI.L2-3.14.3 — Monitor system security alerts and advisories and take action in response.

What this control requires

Monitor system security alerts and advisories and take action in response.

Source: CMMC L2 v2.13 SI.L2-3.14.3 / NIST SP 800-171 R2 3.14.3 (official control text).

Why this matters

Organizations face a constant stream of newly discovered vulnerabilities affecting their operating systems, applications, and cloud services. Attackers exploit known vulnerabilities within hours or days of public disclosure. This control requires active monitoring of authoritative security information sources and documented response when threats affect your systems. Without this process, critical patches go unapplied, known attack vectors remain open, and security incidents become inevitable. Effective alert monitoring protects CUI by ensuring vulnerabilities are identified and remediated before adversaries can weaponize them against your environment.

What evidence assessors expect

Assessors typically look for: PDF, screenshot, CSV export. FORCE coaches you through the exact implementation steps and captures each artifact in-platform.
