Which of the following is an advantage of utilizing security testing methodologies to conduct a security audit?

Security testing methodologies such as OWASP Testing Guide, PTES, or NIST SP 800-115 define step-by-step processes that can be executed consistently across different engagements and over time. This repeatability ensures that no areas are missed, results are comparable between audits, and findings can be tracked for improvement - the primary advantage over ad-hoc testing approaches.

Security testing methodologies typically require skilled practitioners to interpret results and adapt techniques; they are not designed to be run by anyone simply via command-line scripts without expertise.

Many security testing methodologies require licensed tools, specialized expertise, or vendor support that can be costly - low cost is not a defining or guaranteed advantage.

Security testing methodologies are generally industry-developed standards and best practices, not government regulations; compliance frameworks may reference them, but the methodologies themselves are not subject to government regulation.
