Security Hardening

Harden Security Configuration with Secure Defaults

Many security failures do not require a broken cryptographic algorithm or a sophisticated exploit. A system can expose unnecessary services, leave a sensitive feature enabled, grant broader access than intended, or silently keep an old setting after the application changes. This is a secure configuration problem. The software may be capable of operating safely, but its deployed settings place it in a riskier state. A useful defensive mental model is simple: begin from a known secure baseline, make every relaxation intentional, and verify that the deployed system still matches that intent. This reduces the number of accidental paths from a normal installation to an exposed one.
