As I read this, it looked like you mean that Python is NOT good for security programming?  I hope I misread...  (Python is the driving force behind Immunity CANVAS, as well as many other tools.)

My vote goes to Python or Ruby, altough, from my learning, I found Python a bit easier, from the start.  As someone else had noted, though, once you truly understand a language, others come more easily, as it's more about specific syntax and API's, when you change languages.

Good luck!

This is what i see most:

C - Learning/Knowing C is the best way to know the machine inside and out, including how to exploit it.

Perl - Most hacking tools are written in perl or python

Python -Most hacking tools are written in perl or python

Ruby - Metasploit development is in Ruby

BASH and CMD.exe - learning your way around the command lines saves you valuable time during post exploitation or incident handling, depending on what you do

Powershell - Quickly becoming a replacement for scritping tasks that would usually take multiple convoluted commands in cmd.exe and builds in bash commands as well

Not wanting to take this too far off topic, but I'd second Synjunkie and Jhaddix advice regarding powershell; in the future you're going to at least need a basic knowledge of it's fundementals.

Powershell was a recent topic presented by Jonathan Noble at a SuperMondays gathering, the video of the presentation may be a good way to spend a few minutes this Friday afternoon to get a passing familiarity of PowerShell's abilities.

I now return you to you're previously scheduled programming language holy war...

I am a fresher, do i need work experience to do pursue CCNA Security??

Yes BillV, I have completed CCNA, now I want to pursue CCNA Security and then CCSP, any suggestions?? I want to get into the field of network security. Thank You.
