NIST SP 800-53 RA-5: vulnerability monitoring and scanning, explained

RA-5, in the Risk Assessment control family, is one of the most direct vulnerability-scanning mandates in any major framework — it names scanning explicitly. Here's what the control requires, and how Vooki Pro's scans and reports support it.

"Start 7-Day Trial" submits a request — Vooki Pro's team reviews it and sends the trial license and installation instructions; it is not an instant self-serve activation.

The requirement

What RA-5 actually requires

Scan on a schedule, and on new threats

Organizations define their own scan frequency (or random-interval selection), but the control also requires scanning when newly reported vulnerabilities are identified that could affect the system — a scheduled cadence alone isn't the full requirement.

Interoperable tools

Tooling should support standardized formats for platforms, software flaws and misconfigurations, checklists and test procedures, and impact measurement — enabling automation and consistent comparison across tools and time.

Analyze, remediate, report

Scan reports must be analyzed and legitimate vulnerabilities remediated within organization-defined response times tied to a risk assessment — and findings shared with defined personnel, partly to help prevent the same flaw recurring elsewhere in the organization.

Keep the tool current

Scanning tools must be updatable so newly disclosed vulnerabilities aren't silently missed — an ongoing operational requirement, not a one-time setup step.

Sourced from the FedRAMP-hosted copy of the NIST SP 800-53 Rev. 5 catalog (RA-5). Specific remediation-timeframe figures sometimes cited alongside RA-5 (e.g. monthly/weekly scan cadences, 15/30-day remediation windows) come from FedRAMP program policy layered on top of the base NIST control, not the NIST text itself — we have not independently confirmed FedRAMP's current figures and have left exact numbers out of this page.

Where Vooki Pro fits

How Vooki Pro maps to RA-5

What it covers

Scheduled, recurring scans on whatever cadence your organization defines directly satisfy RA-5's core scanning requirement for the web-application and API layer. CVSS scoring on each finding supports risk-based remediation timeframes; automated retest documents that remediation actually happened; and the findings browser, filterable by scan and severity, supports the "share findings with defined personnel" element.

What it doesn't cover

RA-5 sits within a 20-family control catalog covering access control, configuration management, incident response, and far more — RA-5 is one control among well over a thousand across the full catalog. Vooki Pro addresses the application-layer vulnerability-scanning piece specifically, not infrastructure/network scanning or the rest of the RA family.

The NIST 800-53 compliance report

Exporting a scan as a NIST SP 800-53-mapped report (HTML or PDF, via the Export menu or the CLI's compliance_framework: nist config) gives you dated, reproducible documentation to support RA-5 evidence collection — including for programs like FedRAMP that build on the 800-53 catalog.

FAQ

Common questions

What does RA-5 require?
Scanning for vulnerabilities on an organization-defined schedule and whenever new vulnerabilities are identified that could affect the system, using tools that support standardized formats, analyzing scan reports, remediating legitimate findings within organization-defined timeframes based on risk, and sharing results with defined personnel to help prevent similar flaws elsewhere.
Does NIST 800-53 set a fixed scan frequency?
Not in the base control — scan frequency is an organization-defined parameter. Specific programs that adopt the catalog, like FedRAMP, set their own cadence on top of it (commonly monthly for operating systems, networks and web applications, depending on baseline); we have not independently verified FedRAMP's exact current figures and don't state them as fact here.
Does Vooki Pro generate a NIST 800-53 compliance report?
Yes — scan findings can be exported as a report mapped to NIST SP 800-53, in HTML or PDF.

Unverified, explicitly not claimed: specific FedRAMP scan-cadence and remediation-window figures (e.g. 15-day/30-day deadlines by severity) — these appear in third-party sources but were not confirmed against FedRAMP's own current documents, so they're left out of this page.
