RE: What is being a pen tester really like?

Rahul,

Sadly, I have to agree with a large portion of what Paul says. Aside from
some specialised areas or situations, security assessment and penetration
tools have advanced to a point where you could get by with simply taking
canned reports and output and presenting it to your clients. IMHO, this
narrowly qualifies as true pen-testing but even without those tools
pen-testing isn't exactly rocket science.

Now being a *good* pen-tester... That's the real distinction. It's one thing
to be comfortable and proficient with pen-test tools (nessus, Core IMPACT,
Metasploit, webinspect, password tools.. the list is long) so that you can
present reliable results and recommendations. It's another thing entirely to
take those tools and wring every last ounce of performance and use from
them. Paul's Mario Andretti metaphor is a good one. The good pen-testers not
only understand and can interpret the information they gather but also
understand in detail the underlying processes and implications of what they
see (or don't see). Being able to infer from a limited dataset what
weaknesses exist and how to fully take advantage of them is not an easy
thing to pick up. It requires time, patience, experience, and a healthy dose
of paranoia. While your coding background will be of help, especially if you
want to code or modify existing exploits or tool modules, it's not as
relevant as understanding the tcp/ip stack or other more basic technical
knowledge... And being able to see the big picture from the bits and pieces
you collect.

The really rare pen-tester not only has the technical chops but can
communicate them in ways that even a 3yr old (or executive heh) could
understand. I've met people with technical depth who can run rings around me
but with very few exceptions couldn't communicate their way out of a wet
paper bag. I've also met people who are effective communicators but wouldn't
know a SYN ACK if it bit them in the nether regions. The ability to take
complex data and present it in an easy to understand format is difficult.
The fun part of pen-testing is the actual pen-testing itself... The hard
part (and the most time consuming) is writing it all down and documenting
the findings.

In my experience the day-to-day of the pen-tester experience can be summed
up pretty easily: "10 minutes of thrills followed by 10 hours of utter
boredom."

Hope that helps.
