Which term best describes a proactive approach to detect unauthorized access attempts based on traffic signatures?

• A. Proactive
• B. Unauthorized Access
• C. Reconnaissance
• D. Informational

Answer: (A)

Detecting unauthorized access attempts in a proactive way means actively monitoring traffic for known attack patterns and signatures and acting before any breach occurs. This approach, using signature-based detection to spot suspicious activity in real time, is what the term Proactive captures. It emphasizes taking action ahead of time rather than waiting for a breach to reveal itself. The other options describe either the event itself (unauthorized access), a preparatory action attackers might take (reconnaissance), or data that isn’t about the detection approach (informational), so they don’t fit as well.
