    Is there really a need to worry about that?

    (That is a question. I don't know the answer. I had been under the impression that security against attacks wasn't really a concern for developers, that processes in iOS are so sandboxed that it's really apple, not the developer's, concern.)

    I think if you are a new iPhone programmer, the least of your worries is attack vectors. Right now you should be concentrating on learning the fundamentals.

    For starters, don't use C strings or malloc'd buffers for any user or network input. Use APIs that use NSStrings and NSData for all input.
