# Actionable Guidance for Tenable # Generated: 2026-08-04 11:00:54 # Step 1: Navigate to Tenable Vulnerability Management Console → Explore → Findings # Purpose: Identify existing exposed N-able N-central infrastructure using historical scan data # Expected: By applying the filter 'Vulnerability.CVE is equal to [Insert specific N-able CVE, e.g., CVE-2024-2806]' or 'Plugin Name contains N-able N-central', you will generate a list of currently known vulnerable assets and their exact IP/hostname. # Step 2: Navigate to Tenable Vulnerability Management Console → Scans → Create Scan → Advanced Network Scan # Purpose: Actively probe the environment with the latest plugin set to discover unpatched or shadow IT N-central servers # Expected: A newly executed scan targeting management subnets or external IPs, resulting in an updated vulnerability report that confirms the presence or absence of the N-able flaw. # Step 3: Navigate to Tenable Vulnerability Management Console → Dashboards → Add Dashboard → Search 'CISA Known Exploited' # Purpose: Track the remediation progress of this specific flaw alongside other actively exploited vulnerabilities # Expected: A populated dashboard providing a high-level visual overview of all CISA KEV exposures, allowing security teams to prioritize the N-able remediation based on active threat intelligence. # Verification Steps: # - Verify scanner plugin sets are fully updated before running the targeted discovery scan by navigating to Settings → Sensors. # Expected: The 'Last Updated' timestamp for all active Nessus scanners reflects a time within the last 24 hours, ensuring the specific N-able N-central plugin is present. # - After the IT team patches the N-central server, navigate to the original finding in Explore → Findings, select the vulnerability, and click 'Launch Remediation Scan'. # Expected: The scan completes successfully and the vulnerability state for the N-able N-central asset automatically transitions from 'Active' to 'Fixed' in the Tenable console.
