Security testing examines systems and software for weaknesses that could let an attacker bypass intended protections. It combines automated checks and human investigation, then turns reproducible findings into repair work and retesting.

Security testing

Security testing is the controlled examination of a system to find and validate weaknesses in its protections. It asks whether security requirements hold when software receives malformed input, credentials have different privileges, components are misconfigured, or an authorized tester behaves like an attacker.

The subject is broader than penetration testing. A vulnerability assessment searches for known or suspected weaknesses and estimates their exposure. A penetration test attempts selected attack paths to show what an attacker could achieve. Static analysis examines source or compiled code without running the target. Dynamic analysis interacts with a running application. Configuration review, dependency analysis, fuzzing, and manual business-logic tests cover other parts of the attack surface.
