Auditing Tools: Scan the Scanner

There are a number of vulnerability assessment tools available on the block. The options you choose could determine what you end up with. If you like to work in a GUI environment then you may end up with a commercial product. If you like programming and command line then you may as well download open source products and tweak it to your objectives.

Full scans can generate a lengthy report of 1000 pages or so. Analyzing that would be difficult. Manage the scans to suit your most immediate need. Also find out if the scanner gives updates to its ‘what to scan?’ database. Look up http://www.sans.org for more details on scans. Some products are given below.

What ever be the scanner these are a few basics that you need to look into. Scanners are not truly stealth; some of the scanners are intrusive and can cause a crash in the systems. Not all scanners can provide you a complete vulnerability scan. There are many other vulnerabilities being discovered and a program or code is developed to slip packets through your firewall. Vulnerability scanning and risk management is a continual process and cannot be ignored in the present day internet environment.
