Security is a habit, not a feature. The fastest progress for me came from small, repeatable checks in daily work.
Instead of huge audits, I focus on how defaults and data flows behave when something goes wrong.
habits that stuck
- Start every feature with a quick threat model.
- Prefer secure defaults even if they feel strict.
- Log enough to debug without leaking secrets.
- Write tests for the failure path, not just the happy path.
It is not perfect, but the mindset shift makes every release safer.
