Publisher Summary The Nessus Knowledge Base gives power to both the analyst writing tests, and the administrator running the scanner. The security analyst benefits from being able to write more efficient, less bandwidth-hungry tests, while the administrator benefits from decreased network traffic while maintaining his security posture at acceptable levels. The decision to use Knowledge Base saving and to limit future scans based on data stored within the Knowledge Base is a tricky one, however, and should be carefully examined before execution. The bulk of the settings governing the use of the Knowledge Base during a scan can be found under the KB tab of the Nessus Setup graphical user interface (GUI) on the client. These settings can be used to enable or disable Knowledge Base saving, and to guide what the scanner can do with the stored Knowledge Base data and for what period of time. A Nessus user might choose to scan or ignore hosts with existing Knowledge Bases and might choose to run different permutations of the NASL script families based on the information stored in the target host's Knowledge Base.
