A security analyst needs to investigate a potential data breach that is suspected to have occurred over the past week. The investigation requires correlating log data from firewalls, servers, and intrusion detection systems to identify suspicious patterns and trace the timeline of events. Which of the following tools is BEST suited for this type of historical analysis and data correlation?
The correct answer is a security operations dashboard. These dashboards, typically integrated with a Security Information and Event Management (SIEM) system, are specifically designed to aggregate, correlate, and visualize log data from numerous sources over time. This makes them the ideal tool for historical analysis and identifying trends or patterns indicative of a breach. A real-time network performance monitor focuses on current bandwidth and latency, not historical log correlation. A packet capture utility provides deep, low-level data but is cumbersome for analyzing long-term, aggregated trends across multiple systems. A system vulnerability scanner is used to identify unpatched systems and misconfigurations, not for analyzing event logs to investigate an active or past incident.
