Hardening Debian for the Desktop Using Grsecurity

I recently built a desktop system that I think is reasonably secure. It’s running Debian sid, also known as “unstable” — though in the Debian desktop world that just means you get to use the newest software. It’s just about as stable as “stable”, and besides, #yolo. It’s also running a grsecurity-patched Linux kernel and PaX, technologies that make Linux way more secure. Grsecurity protects you against memory corruption attacks, such as buffer overflows.
