The Linux Intrusion Detection System is a patch which enhances the kernel's security. When it's in effect, many system administration operations can be made impossible even for root. You can turn the security protection on or off on the fly and you can hide sensitive processes and prevent anyone from using ptrace or any other capability on your system. LIDS can also provide raw device and I/O access protection.

The libsafe library protects against buffer overflow and format string attacks. It works by putting a wrapper around dangerous functions that contain any buffer overflows within the current stack frame, so that the return address can not be changed. Libsafe works with any existing pre-compiled executable and can be used transparently, even on a system-wide basis.
