IT Computer Security magazine “Hakin9” is offering free .PDF downloads of select magazine issues. Hakin9 is an excellent magazine that offers computer security tips, articles on attack and defense and penetration testing.
In my opinion, it is one of the best White Hat/ Ethical Hacking magazines available. The writers are computer security and penetration experts from around the world. These include SANS certified experts and Microsoft certified trainers.
I really enjoy this magazine. My only negative, and it is minor, is that being a foreign edited magazine with several foreign writers, sometimes I have trouble understanding the wording in the articles.
But, it does not distract from the excellent fountain of information that this magazine contains. Check out their website and downloads at Hakin9.org.
