An organization wishes to scrutinize network traffic to detect anomalies, like substantial data transfers during off-peak hours. Which solution is most fitting for generating insights into such network traffic behaviors?
NetFlow, a network protocol for collecting IP traffic information and monitoring network flow,
Antivirus software, designed to detect, prevent, and remove malware,
Security Information and Event Management (SIEM) solution, a comprehensive approach to security management that aggregates and analyzes security events,
Simple Network Management Protocol (SNMP) traps, a protocol used for managing network equipment and handling event notifications,
The best solution for generating insights into network traffic patterns is NetFlow, because it collects detailed information about the data flows within the network, including source, destination, and volume of data, which is key for detecting irregular large data transfers occurring after standard operational hours. Simple Network Management Protocol (SNMP) traps are typically used for real-time event notification and not for in-depth traffic analysis. A Security Information and Event Management (SIEM) solution centralizes security alerts and logs but does not inherently provide the detailed network flow analysis characteristic of NetFlow. While antivirus software protects against malware, it does not offer network traffic pattern analysis and therefore would not be an effective tool for this particular requirement.
