Installing & Configuring Nessus - Scan Network Vulnerabilities




Vulnerability scanning has always played a vital part to strengthen the security of the server at which your useful sites are hosted. It can also be used to scan the security of the computer which is connected to the internet. It basically scans the open ports and then checks for the vulnerabilities present in the services running on those ports.It is always useful for a server admin or else of any system to be aware of the weak points of the server security so that he may make it a hack proof system. That's why I decided to post a tutorial on this site to help you all scan for the weakness in accordance with the latest increasing available exploits.I suggest using backtrack as every thing is already cooked up there. In any other Linux you may have to install all the packages first.
