Which tool is designed to analyze network logs in real time for suspicious log events?

• A. SIEM
• B. Log aggregation tool
• C. Network analyzer
• D. Packet sniffer

Answer: (A)

The suitable tool for analyzing network logs in real-time for suspicious events is a Security Information and Event Management (SIEM) system. SIEMs aggregate and analyze log data from various sources within an IT environment. They possess capabilities for real-time monitoring and alerting, allowing security analysts to identify and respond to threats as they occur. SIEM tools often incorporate advanced analytics and correlation rules to automatically detect suspicious behavior across different systems and networks, enhancing the organization's ability to respond quickly to potential security incidents. In contrast, log aggregation tools primarily focus on collecting and storing log data from multiple sources for later analysis, but they may not provide the real-time analysis and alerting features that SIEMs offer. Network analyzers are generally used for analyzing traffic patterns and protocols within a network but do not specialize in log analysis. Packet sniffers capture and inspect packets traveling over a network, primarily useful for troubleshooting and traffic analysis, rather than for real-time log event analysis.
