Sadly, the long enjoyed Easter holiday is over so now it’s time to go back to work again. I have just submitted a homework for my course in Networked Security Systems, a course that I enjoy following it (at least until now). This is one of my optional courses that I could choose from and it seemed interesting. Network security is today one of the most important things in the world of IT&T since we live now in the digital world.
This homework is also one of the homeworks I really enjoyed doing, because it doesn’t use a lot of those head damaging mathematics and weird symbols representing something as in my previous homeworks and assignments. It presents conceptual problems and puzzles instead, which is just the thing that I like doing. Here is an example of the puzzle:
“Guvf vf na rknzcyr bs n Pnrfne pvcure”
Can you decode it?
