Which description best fits an anti-virus sensor system?

• A. Snort
• B. A collection of software that detects and analyzes malware.
• C. A VPN
• D. A hardware router

Answer: (B)

Antivirus sensor systems are software-based detectors that monitor for malware by analyzing files, processes, and behavior on endpoints. They use signature databases to recognize known threats and employ heuristic analysis and sandboxing to catch unknown or suspicious activity, then quarantine or remove what they find. This fits the concept of an antivirus sensor because the core function is detection and analysis of malware through software running on devices. Snort, while powerful, is a network intrusion detection system focused on identifying malicious traffic, not on detecting malware on individual hosts. A VPN provides secure, encrypted connectivity and isn’t about detecting malware. A hardware router handles packet routing and network traffic flow, not malware analysis.
