Security Test and Evaluation (ST&E) is a component of risk assessment. It is useful in discovering
system vulnerabilities. For what purposes is ST&E used? Each correct answer represents a
complete solution. Choose all that apply.

A.
To implement the design of system architecture

B.
To determine the adequacy of security mechanisms, assurances, and other properties to
enforce the security policy

C.
To assess the degree of consistency between the system documentation and its
implementation

D.
To uncover design, implementation, and operational flaws that may allow the violation of
security policy

Explanation:
Security Test and Evaluation (ST&E) is a component of risk assessment. It is useful
in discovering system vulnerabilities. According to NIST SP 800-42 (Guideline on Network
Security Testing), ST&E is used for the following purposes: To assess the degree of consistency
between the system documentation and its implementation To determine the adequacy of security
mechanisms, assurances, and other properties to enforce the security policy To uncover design,
incorrect. ST&E is not used for the implementation of the system architecture.
