Betreff: Re: How do VA scans work technically

Hi,

Thanks for all the gr8 replies.

Showing of already remediated vulnerabilities was what i was concerned.
So i always have to take the reports from these scans with a pinch of
salt. They even might miss something.

But what if i am running say a web server on a non-standard port and
have really disabled all settings that might allow an outsider to get
a banner or version number of underlying application then will the
scanners still be able to do some heuristics and come out with nearly
correct answers.

Can someone point me to any link that will provide more insight into
this process.

Regards
Aseem

Nessus can ne configured to perform safe scans. It will still for blank
root, as and administrator passwords under that config.

So, it depends on your definition of exploit :)

Nessus can also be configured to prrerform brute force attacks using a
hydra
plugin/module

You also perform thorough tests/scans.

I have feeling that you are wanting to if nessus and qualys operate like
metasploit, canvas or other exploit frameworks.

I would say no. But nessusbis very flexible and you can customize It and
create your own plugin to do just about anything.

There is plenty of documentation and help online.

Hey,

Can someone tell me (any weblink , any ebook, or direct answers) as to
how the VA scans like those of Qualys or Nessus work?

How do they find the vulnerabilities of a system without ever
exploiting
it?

Regards
Aseem
