Hi good one being interested in security, it is a really interesting field of which I have some experience. It depends on what you want to do in security but if you want to be able to write buffer overflow exploits you are going to need some knowledge in C, and it also wouldn't hurt to learn some ASM at least on the theoretical level so you can tell whats going on at the memory register level. An excellent resource for information on this is this book The Art of Exploitation Also the Linux kernal is written in C. K & R do a great introductory C book ANSI C which I would recommend as a starting point.

Other notable languages for security guys are Python and Perl oh and Bash scripting too. You will meet that many different challanges along the way that you will have to be a swiss army knife of tricks.

One you have nailed either language though it is pretty easy to hop between the two, it's really just a case of knowing what libraries are available to do certain jobs. I started coding in Java before I used C# but found that when I needed to start learning C# for some dev work that the transition for the most part was painless. Infact it was harder going back to Java after being spoiled by the VS IDE.
