Re: I want have a carrier on Security? 12 years 7 months ago #16107 - articles etc - reading room - the whole site pretty much

Subscribe to the security-basics list if you're completely new. Other lists such as the pen-test list are handy places to ask a question.

Get yourself a Linux live CD such as Auditor and start playing around with the tools. Install virtual machines of different operating systems and learn their security features, exploit vulnerabilities in them.

And more important than all the others -- learn how to program. You should be a capable C/C++ coder at the very least. Assembly language is a must for reverse-engineering, vulnerability development and exploit creation. You'll also want to learn Perl or Ruby as a scripting language for quick little tools and output parsing.

The worst thing you can do is put yourself in a situation where you are not capable of building automation into your own work. If you spend alot of your time saying 'I wish there was a program to do X', then you will not be effective in a proper security job.

Of course there is stuff like compliance / sarbanes-oxley and all that other rubbish that so-called consultants keep spitting out as 'security'. It's a load of hogwash. Computer security is about bits and bytes... the better you understand those, the better you'll be


Ps. I forgot to mention, this process can take a long time -- it helps to have a mentor or someone significantly more skilled than you to guide you.

Loads of useful information there, i am also trying to move into a more security focused job role so thanks for the post :)

I am thinking of doing the CISSP, can what do you all think about this accreditation ?

I suppose i should try and find time to get back into some programming then, hehe :)
