How to Use the Nessus Vulnerability Scanner

Last month I posted a brief review of the open-source vulnerability scanner Nessus (see Profile: Nessus Vulnerability Scanner). Harry Anderson has written a detailed introduction to the Nessus program from installing it to using it and describing some of the more advanced options available. If you are interested in seeing what this free vulnerability scanner can do for you I recommend you take a look at this SecurityFocus.com article first: Introduction to Nessus.
