Linux Security Articles

Most Linux outages that get labeled as ”security issues” are not breaches. They are TLS failures that sit quietly until a renewal expires, a client updates, or a service starts refusing connections for reasons that look unrelated at first. By the time users notice, traffic has already stopped, and the only clue is a vague handshake error buried in a log file.

Linux security is not about stacking tools and hoping for the best. It comes down to deliberate configuration, steady maintenance, and systems that can withstand real-world pressure.

Most of us don’t decide to deploy AppArmor. We inherit it. It’s already enabled on the system, already loaded at boot, and already assumed to be doing something useful. Over time, it fades into the background. That’s usually when it starts to matter.

I keep seeing Rust show up in places it never could have five years ago. Kernel-adjacent tools. Security agents. Parsers that used to be a pile of careful C and comments warning you not to touch anything. It’s not because developers suddenly got more patient or because everyone decided memory safety was fun. The cost equation changed, and AI coding is a big part of why.
