QuestionQ692

Scanning and Mapping

An analyst performed a Nessus vulnerability scan against a business-critical system on the production network with Dangerous plugins enabled. The scan brought down the target host without issuing an alert while it was running. How could the scan have prevented the target host from crashing?

  • A Never scan production networks, since they are business critical at all times
  • B Scan the business critical systems, after you disable dangerous plugins
  • C Do not scan any business critical systems, since they have other priorities
  • D Use a different vulnerability scanner, since Nessus is dangerous in this situation
Explanation

Nessus Safe Checks disable plugins that may adversely affect a remote host. Disabling dangerous plugins allows the business-critical system to be assessed without executing checks that can crash services or targets in a production environment.
