11.6 Personal checklist: what to improve immediately
This section turns the topic into a practical checklist. The goal is to make the safe action easy to repeat when the situation appears in real life.
Use it as a pause point before publishing, clicking, sending, approving or changing access. A short checklist is useful only when it is simple enough to apply under pressure.
Small repeated habits often prevent the most common incidents.
Sharing passwords or leaving devices unlocked for convenience.
Create a short daily security routine.
Device safety review
Review one smartphone and one computer. Check screen lock, updates, app permissions, browser extensions, backups and account sessions.
