Best practices
Use these Best practices to get the most from your investment and set the foundation for becoming a power user:
- Utilize the Tenable vulnerability priority rating (VPR) to prioritize the remediation of the highest risk vulnerabilities first.
- The scan or policy’s Credentials page allows you to configure the Tenable Nessus scanner to use authentication credentials during scanning. Configuring credentials allows Tenable Nessus to perform a wider variety of checks that result in more accurate scan results.
- You can compare two scan results to see differences between them. This comparison is not a true differential of the two results; it shows the new vulnerabilities that Tenable Nessus detected between the older baseline scan and the newer scan. Comparing scan results helps you see how a given system or network has changed over time. This information is useful for compliance analysis by showing how vulnerabilities are being remediated, if systems are patched as Tenable Nessus finds new vulnerabilities, or how two scans may not be targeting the same hosts.
- Use the Live Results feature to view scan results for new plugins based on a scan's most recently collected data, without running a new scan. Live Results allow you to see potential new threats and determine if you need to launch a scan manually to confirm the findings.
