Which protection tool is primarily used to stop ransomware by monitoring network activity?

• A. NetFlow Traffic Analyzer
• B. DNSChanger
• C. DNSQuerySniffer
• D. PA File Sight

Answer: (D)

Ransomware typically reveals itself by mass, rapid file encryption and altered file states on endpoints. To stop it, you want a tool that watches how files are accessed and modified in real time and can intervene when suspicious activity is detected. PA File Sight fits this role because it continuously monitors file-system events—who or what is opening, modifying, creating, or deleting files—and can trigger alerts, block processes, or restrict access when it detects ransomware-like behavior, helping to stop the encryption chain before widespread damage occurs. The other options focus on network-level data: analyzing traffic flows, or sniffing DNS activity. While useful for detecting certain types of malicious activity, they don’t provide the proactive, behavior-based protection at the file level that directly counters ransomware by stopping encryption in its tracks.
