In case you’re not aware, ISECOM (Institute for Security and Open Methodologies) has OSSTMM3 – The Open Source Security Testing Methodology Manual – http://www.isecom.org/osstmm/
There’s an interesting segue to this at
Skip over his ranting about the definition of “hackers”
This is the meat:
Wewrote the OSSTMM 3 to address these things. We knew that penetration
testing the way it continued to be marginalized would eventually hurt
security. Yes, the OSSTMM isn’t practical for some because it doesn’t
match the commercial industry security of today. But that’s because the
security model today is crazy! And you don’t test crazy with tests
designed to prove crazy. So any penetration testing standard, baseline,
framework, or methodology that focuses on finding and exploiting
vulnerabilities is only perpetuating the one-trick pony problem.
Furthermore it’s also perpetuating security through patchity, a process
that’s so labor intensive to assure homeostasis that nobody could
maintain it indefinitely which is the exact definition of a loser in the
cat and mouse game. So you can be sure it also doesn’t scale at all with
complexity or size.
I’ve been outspoken against Pen Testing for many years, to my clients, at conferences and in my Blog. I’m sure I’ve upset many people but I do believe that the model plays up to the Hollywood idea of a Uberhacker,
produces a whack-a-mole attitude and is a an example of avoidance behaviour, avoiding proper testing and risk management such as incident response good facilities management.
I’ve seen to many “pen testers’ and demos of pen testing that are just plain … STUPID. Unprofessional, unreasonable and pandering to the ignorance of managers.
In the long run the “drama-response” of the classical pen-test approach is unproductive. It teaches management the wrong thing – to respond to drama rather than to set up a good system of governance based on policy, professional staffing, adequate funding and operations based on accepted good principles such as change management.
And worse, it
- shows how little faith your management have in the professional capabilities of their own staff, who are the people who should know the system best, and of the auditors who are trained not only in assessing the system but assessing the business impact of the risks associated with a vulnerability
- has no guarantees about what collateral damage the outsider had to do to gain root
- says nothing about things that are of more importance than any vulnerability, such as your Incident Response procedures
- indicates that your management doesn’t understand or make use of a proper development-test-deployment life-cycle
Yes, classical hacker-driven pen testing is more dramatic, in the same way that Hollywood movies are more dramatic. And about as realistic!
“Crazy” is a good description of that approach. Continue reading In praise of OSSTMM
