NIST800 171 · Control 3.14.1 · Priority: critical · Component: System and Communications Protection

### What this control covers

This control requires identifying, reporting, and correcting system flaws, and installing security-relevant software and firmware updates within a defined time period after the release. This includes patches, service packs, hot fixes, and anti-virus signatures. Organizations must address flaws discovered during security assessments, continuous monitoring, incident response, and error handling. This control supports the Flaw Remediation System capability within the System and Communications Protection (3.14) family.

### Why it matters

How quickly and methodically you contain an incident determines the regulatory consequence — most fines are not for the breach itself but for the slow or absent response.

### How to implement

#### AWS

Wire **GuardDuty**, **Security Hub** and **Macie** findings into your ticketing/SIEM via EventBridge. Maintain documented playbooks for IAM-key compromise, EC2 instance compromise, S3 data exposure, and run **quarterly tabletop exercises**.

#### Azure

Use **Defender for Cloud** + **Microsoft Sentinel** with playbooks (Logic Apps) for automated containment — disable user, isolate VM (NSG), revoke session tokens. Keep an on-call rotation in Teams with PagerDuty.

#### GCP

**Org Policy Service** for guardrails and **Config Validator** in CI to pre-check Terraform plans against policy as code (Rego).

#### Google Workspace

Forward the **Admin, Login, Drive, Token and Mobile** audit logs to Cloud Logging (Workspace BigQuery export). Alert on impossible-travel logins, OAuth-scope grants for high-risk scopes, and external Drive sharing of sensitive labels.

#### GitHub

Subscribe to **secret-scanning** alerts and **Dependabot** security advisories; require triage SLAs by severity. For exposed secrets, rotate at the cloud provider FIRST then revoke at GitHub — order matters.

### Evidence to collect

-   `ticketing_workflow` — See the iCompaas Evidence library for the canonical source for this evidence type.

Workflow metrics (ServiceNow, Jira) show approvals and remediation. Focus: Flaw Remediation.
