How can i prevent gdb from attaching to an exe?

Question

I'd like to prevent would-be hackers from attaching to my binary on Linux systems. I see that ptrace DENY_ATTACH can be used on OSX. Is there such option that can be used on linux? How about on Windows?

Thanks for any info!

Such a system call requires kernel support. Even if it existed in Linux, it would be fairly easy to disable by compiling your own kernel.
