Linux security depends heavily on whether a system is still inside its support window. When that window closes, the system keeps running, and nothing on the surface changes, but the updates stop immediately. From that point forward, the release no longer tracks the changes happening in the rest of the environment. The gap isn't evident from uptime or basic monitoring, but it affects how well the system withstands new security pressures.

Most production workloads still land on Linux. That hasn't changed. What's shifted is how teams manage those systems at scale''especially when speed and compliance need to keep pace. That's where DevOps platforms come in. They help unify code, configuration, and control under one roof.

Part 1 covered how Linux keylogging works in user space and why attackers lean on simple hooks or device access to capture keystrokes. Part 2 walked through the GUI layer, showing how the X Server exposes keyboard events long before applications see them. We closed with a promise to move from observing behavior to turning low-level input into usable detection signals.
