What is the BEST source an analyst could review to understand how an incident occurred due to a lack of patching?

Security logs serve as a critical resource for understanding how an incident occurred, especially in the context of lacking necessary patches. They provide detailed records of system activities, including timestamps, user actions, and other events related to system security. By analyzing security logs, an analyst can identify unusual activities that may indicate exploitation of vulnerabilities due to unpatched software. For instance, security logs can reveal attempts to access vulnerable applications, record the exploitation of specific vulnerabilities, or show indicators of compromise, all of which help in tracing the sequence of events leading up to the incident.

Additionally, security logs can provide insights into when the patches were applied or missed, helping to pinpoint the timeline of the incident. This is vital for understanding not just what happened, but how it could have been prevented through timely updates.

The other options, while useful in their own right, do not provide the same level of immediate insight into the specific actions that led to the incident stemming from a lack of patching. Vulnerability scan outputs might identify unpatched vulnerabilities but do not give the context of actual exploitation events. The baseline report offers a reference to expected configurations and behaviors but does not contain real-time data about the incident. Correlation of events can showcase patterns and relationships among various logs but may lack
