I'm a little rusty when it comes to Linux security, and I think I may have asked this before on Twitter but couldn't get a conclusive answer - is there not any measure that one can take to ensure a binary's integrity on a stock normal Linux distro?

It doesn't seem like the concept of code signing exists on Linux beyond the installation packages - what's to stop someone from modifying the binary post-installation without being noticed? I see there's IMA Appraisal, but that doesn't seem to be enabled by default in the Linux kernel.
