Security work is repetitive by nature — checking the same permissions, scanning the same logs, verifying the same configuration on dozens of servers — and Bash scripting is what turns a manual checklist into a repeatable, consistent, and auditable process. A well-written security script does not just save time; it removes the human inconsistency where a tired analyst skips a step at 2 a.m. that they would never skip during a calm afternoon review.

💪 Think of it like fitness: injuries follow a predictable chain — poor warm-up, then form breakdown, then compensation, then the actual tear — and a good physio catalogs where each patient's chain can be interrupted early, rather than only treating the tear afterward. MITRE ATT&CK is the sports-medicine literature of intrusions: a public catalog of every observed breakdown pattern, organized by the stage it serves — how attackers get in, how they escalate, how they extract. Coaches worldwide describe an athlete's risk in that shared vocabulary. This reveals ATT&CK's real value: intrusions become a sequence you can interrupt at stage two, not a disaster you discover at stage five.
