Which tool is used for real-time traffic analysis and can detect port scans, fingerprinting and buffer overflow attacks?

• A. Nmap
• B. OpenVAS
• C. Snort
• D. Wireshark

Answer: (C)

Real-time traffic analysis for intrusion detection relies on monitoring network packets as they flow and automatically identifying patterns that match known attack techniques. Snort fits this purpose best: it’s an intrusion detection system that analyzes traffic on the fly, uses rule-based signatures to spot suspicious activity, and can alert or even block traffic. The rules include detections for port scans (lots of connection attempts across many ports), fingerprinting (trying to identify a target’s OS or services), and buffer overflow attempts (payload patterns that attempt to overflow buffers). Because it continuously analyzes live traffic and can enforce protections, it’s ideal for spotting these attacks as they occur. Nmap is a network scanner used to map hosts and services. OpenVAS is a vulnerability scanner that looks for known weaknesses in systems. Wireshark is a packet analyzer used for detailed manual inspection of traffic. While Wireshark helps you examine packets, it doesn’t automatically detect and alert on attack patterns in real time the way Snort does.
