Tool Behavior
This connector wraps the FedRAMP POA&M Automation Tool — a Python CLI that manages the full vulnerability finding lifecycle from scanner import through FedRAMP 20x VDR generation.
What it does
- Parses raw scanner exports (Nessus, Tenable, Qualys, Wiz) into a structured FedRAMP POA&M
- Auto-deduplicates findings across scanner imports using title + asset identifier
- Enriches findings with NIST 800-53 control mappings via keyword matching
- Manages finding lifecycle: update, close, deviation (false positive / operational requirement)
- Generates FedRAMP 20x VDR reports with live CISA KEV and EPSS enrichment
- Generates per-release Product VDR reports for customer-facing vulnerability disclosure
- Outputs machine-readable JSON alongside every Excel report
VDR Classification Logic
Each finding is classified using live threat intelligence:
- CISA KEV: Finding CVE is checked against the live CISA Known Exploited Vulnerabilities catalog. KEV findings are bumped to minimum N3 adverse impact.
- EPSS: Exploit Prediction Scoring System score fetched from First.org API. Score ≥ 0.10 triggers LEV classification.
- LEV/NLEV: Likely Exploitable / Not Likely Exploitable. Determined by KEV membership, EPSS score, and severity fallback.
- IRV/NIRV: Internet Reachable / Not Internet Reachable. Derived from keywords in asset identifier and weakness description.
- N-Rating: N1 (lowest) to N5 (highest) adverse impact. Base rating derived from severity, then adjusted upward for KEV and IRV+LEV combinations.
Evaluation Deadlines
Per FedRAMP 20x baseline:
- High: 2 days from detection
- Moderate: 5 days from detection
- Low: 7 days from detection
Auto-Acceptance Threshold
Findings open 192+ days are automatically moved to the Accepted Vulnerabilities sheet per VDR-TFR-MAV.
Update Frequency Requirements
- High baseline: Weekly (every 7 days)
- Moderate baseline: Every 14 days
- Low baseline: Monthly (every 30 days)
Control Coverage
This connector maps findings to NIST 800-53 Rev 5 controls via keyword matching across 30+ control families including SI-2, RA-5, AC-2, AC-3, SC-8, SC-28, AU-2, CM-6, CM-7, and others.
Failure Modes
- Missing openpyxl: Install with
pip install openpyxl - CISA KEV unavailable: Offline fallback uses severity-based LEV classification
- EPSS unavailable: Offline fallback uses severity-based LEV classification
- POA&M file open in Excel: Close the file before running any write command
- Duplicate findings: Automatically skipped on import — same title + asset identifier
Limitations
- Product VDR requires a manually maintained vulnerability CSV — it does not auto-discover product vulnerabilities
- NIST control mapping is keyword-based, not authoritative — review mappings before submission
- AI remediation text requires Ollama running locally with the Mistral model
