Re: Pen testing techniques

Too add to this, it is important to remember the capabilities of the
tool. Many other tools exists that perform these basic tests too, but
they are often not even sophisticated enough to identify and bypass
client side validation.

Dude, tools are only part of the battle, I agree with Atif

Oh boy... let me intercept this before some others do, lol.

You cannot rely on Core or any one tool for a pen test AT
ALL. It's a
great tool but there is SO much more to pen testing than
relying on
one single tool, in fact that is the cardinal sin. You need
to follow
a methodology and use an array of tools and manual
techniques to make
sure the test is thorough. When I do a web app pen test,
the tools
never find some of the nastiness that I do manually. Never.
Web apps
are a curious breed because they are usually custom coded
in some way
so every single one is different, making standard tools
less useful.

I am not surprised by your Core Impact results, it is a
great tool but
they are new to the web app game, and it hasn't been
thoroughly
developed yet. No fault of theirs, it just hasn't
matured the way
others have. For web apps I prefer a web app vulnerability
scanner
like Cenzic Hailstorm for the automated dumb stuff like XFS
/ XSS and
basic authentication bypass. You definitely need to do
manual checks,
regardless of what the tools find. Try some injections and
authentication bypass techniques, and, well, everything
else too.
Might want to do a search for the OWASP guide, they have
great info on
web app testing.

Besides all this, have you used anything like nmap to find
open ports
and verify your results? Perhaps Core missed something. Is
a stealth
approach required to emulate a malicious hacker and
therefore your
checks need to be quiet and evade detection?

I highly recommend if you are new to this to take a course
or at least
get some good books. A person really can't jump into
pen testing like
they can jump into product deployment / administration.

Might want to search this list as well, you will find some
helpful
information I am sure.

Good luck.

Hello,
I am new to pen testing and am currently involved in
doing an external
pen test for one of our clients.We are doing it
through Core
Impact.Reconnaisance showed only port 80 as open and
the web server
running IIS 6.0.Core Impact did not find any
vulnerabilities in the
server and hence was unable to penetrate.The web
application was also
tested for SQL Injection and PHP remote file
inclusion and did not
find any vulnerabilities there either.

My question is what else can we do besides relying on
Core Impact for
this pen test.And what impression can a client get if
we say to them
that there are no vulnerabilites in your network or
web app.Its
dificult to digest something like that for a security
specialist that
everythings alright.

Looking forward to some great views.Thanks.

Regards,
Atif Azim
