Which combination of data sources would provide the MOST comprehensive view for investigating increased incidents on a SIEM dashboard?

The combination of network sensor logs, host logs, and automated reports offers the most comprehensive view for investigating increased incidents on a SIEM dashboard because it covers multiple layers of the environment.

Network sensor logs provide insights into network traffic and can help identify unusual behaviors or patterns indicative of an attack or breach. Host logs capture activities and events occurring on individual systems, providing context for user activity and system changes. Automated reports can synthesize data from various sources, allowing for a quicker assessment of trends and anomalies. By integrating these sources, an analyst can correlate events from both network and host perspectives, enhancing the ability to detect, analyze, and respond to security incidents more effectively.

In comparison, the other choices may provide significant information, but they generally focus on more specific or limited aspects of the environment. For instance, application logs and event logs primarily relate to software applications and may not encompass all relevant factors, while firewall logs and intrusion detection logs focus on perimeter security. Router and switch logs largely pertain to traffic routing rather than the broader network and host interactions. These limitations can make it harder to fully understand the nature of increased incidents without the comprehensive insight offered by the combination in the correct choice.
