What is Security Testing and Evaluation STE?

Understanding Security Testing and Evaluation STE

Security Testing and Evaluation (ST&E) provides a comprehensive assessment of whether security controls are properly implemented and operating effectively. Unlike basic vulnerability scanning, which focuses on known technical flaws, ST&E examines the entire security architecture—evaluating policies, procedures, configurations, and technical controls against established requirements. The process typically includes document reviews, interviews with personnel, configuration analysis, vulnerability scanning, and hands-on testing of security mechanisms. It's particularly valuable before systems go into production or after significant changes, to verify that security requirements have been met and no new vulnerabilities have been introduced. Government agencies and regulated industries often have formal ST&E requirements as part of their system authorization processes, while other organizations may conduct similar assessments under different names. Effective ST&E programs establish clear testing methodologies, acceptance criteria, and remediation processes for addressing any deficiencies discovered.
