Best Practices for Effective Scanning

Here are some best practices for effective scanning:

  • Network Accessibility: Ensure that the scanner has the necessary network access to reach the Qualys Enterprise TruRisk™ Platform and all intended scan targets. This may involve configuring firewall rules and routing to allow scanner traffic.

  • Avoid Scanning Through Firewalls: To maintain scan accuracy and performance, it’s recommended to deploy scanners within the same network segment as the target assets, avoiding scans that traverse firewalls. This practice helps in reducing potential latency and interference.

  • Regular Updates: Keep the scanner appliance updated to the latest version to benefit from improved features and vulnerability signatures.

Performance Optimization

  • Load Distribution: In large environments, distribute scan loads by deploying multiple scanner appliances across different network segments. This approach enhances scan efficiency and reduces the impact on network performance.

  • Scan Scheduling: Schedule scans during periods of low network activity to minimize potential disruptions. Qualys allows for flexible scheduling to accommodate various operational needs.
