• As usual, Tarek is the man. This course is very well thought out and he explains every topic thoroughly. Very well put together, great pace, highly interesting – plus you get labs to see exploits done in real time. Highly recommended!
• You explains the things really well and in simple english. I know what DACL ,SACL were. But I know how frustrating they where when I learned about them last year. You explained it really well that a beginner can understand.
