Which tool is designed to detect both known and unknown threats on mobile devices by analyzing device behavior?

• A. zIPS
• B. Snort
• C. Suricata
• D. AlienVault OSSIM

Answer: (A)

Detecting both known and unknown threats on mobile devices relies on watching how the device actually behaves, not just matching against a list of signatures. A tool that runs on the device and continuously monitors runtime activity—what apps do, which processes start and stop, unusual permissions or access patterns, persistence techniques, and abnormal network or file-system behavior—can identify anomalies that don’t match any known signature. This behavior-based approach, often powered by machine learning or heuristic rules, enables detection of zero-day or previously unseen threats. That’s exactly what the on-device mobile threat detection tool does: it analyzes device behavior to flag suspicious activity and unknown threats while still leveraging known signatures for known malware. In contrast, network-focused systems like Snort or Suricata are designed to inspect network traffic for known patterns and may miss malicious actions that stay entirely on the device. AlienVault OSSIM is a centralized SIEM that collects logs from various sensors but doesn’t perform the continuous, on-device behavioral analysis necessary to catch unknown threats on mobile endpoints.
