Nessus: Be an instant security auditor

I really like those some proclaimed security auditors who come to you and say they can "detect" security flaws in your products and charge you a butt load of money for it. I must say, they did some good work in convincing you.

But seriously speaking, many so called "sec auditors" out there are just a load of scripting kiddies that run tools then Google the findings and look for resolutions, last but not least, they send you their bill. Well, i am not sure if there's a magician's-code like for security auditors not to "reveal" their tricks to the public, i don't really care actually.

So here's a quick trick to become a sufficient auditor (note, by saying sufficient, i mean, basic or enough-for-now level). Try Nessus 3.0, its a vulnerability scanner for almost anything that have an IP (almost).

Its an awesome tool, that i personally use too when performing auditing but, i would provide this type of auditing for free!.

I would suggest to organizations, large or small, to run a basic security audit on all implemented servers, devices, routers or like i said, anything with an IP to see if its secured at least to known security vulnerabilities out there.

Nessus is fast and agentless that runs on many *nix flavors, Windows, Solaris and Macs and even checks for patch levels if configured to do so. Now, try it out for yourself, but first read the how-to-guide then start. Some scans can crash servers so be extremely careful when running on live environment.

And..drum rolls, best part is, its FREE!!! Enjoy!
