📈 Continuous Monitoring Policy

APJ Enterprise LLC — FedRAMP Moderate | NIST SP 800‑137 | NIST SP 800‑53 Rev.5 (CA‑7, RA‑5, SI‑2)

1. Purpose

Define cadence and responsibilities for ongoing assessment of security controls, vulnerability scanning, and POA&M maintenance.

2. Monitoring Cadence

| Activity | Tool | Frequency | Owner | |—|—|—|—| | External vuln scans | Tenable/ACAS | Monthly | Vulnerability Manager | | Internal agent health | Defender for Endpoint | Daily | SOC | | Config drift checks | Intune/Group Policy | Weekly | SysAdmin | | Log aggregation | Sentinel | Continuous | SOC | | POA&M review | POA&M Tracker | Monthly | ISSO | | Control assessment spot‑checks | Manual/Automated | Quarterly | ISSM |

3. POA&M Lifecycle

1. Identify weakness → 2. Assign owner/date → 3. Mitigate or accept risk → 4. Validate fix → 5. Close & archive evidence.

POA&M Tracking (Sample)

| Weakness ID | Control | Description | Owner | Planned Completion | Status | Evidence | |—|—|—|—|—|—|—| | POAM‑2025‑001 | IA‑5 | Breached‑password screening not enabled | IAM Lead | 2025‑11‑15 | In Progress | Change ticket #321 | | POAM‑2025‑002 | AC‑17 | MFA missing for VPN break‑glass acct | Network Lead | 2025‑10‑30 | Open | VPN config PR #88 |

4. Metrics & Reporting

• Top open POA&Ms by age/severity
• Patch SLA adherence (Critical ≤ 15 days, High ≤ 30 days)
• Endpoint coverage (% with EDR)
• Authentication failures trend & admin activities

5. Evidence Retention

• Logs: 12 months minimum (hot + cold storage)
• Scan results and POA&M exports: 12 months minimum

6. Change Management Linkage

Remediation requiring config change follows CM‑3/CM‑4 processes with rollback plan and approvals.
