A benign disposition is applied when an event is indeed suspicious but ultimately expected and non-threatening in the given environment. This differentiates it from a false positive (incorrect detection) or a true positive (confirmed malicious activity).

Web proxy logs capture every user request to external websites, allowing you to see if a user's browser was directed to the known malicious URL. Proxy logs thus provide direct evidence of web visits, unlike web server logs (which only cover your own servers) or IDS/AD logs.

Mean Time to Respond (MTTR) typically begins when a Notable Event is triggered in Splunk Enterprise Security. This marks the point at which the SOC becomes aware of a potential issue, initiating the response process. The metric captures how quickly analysts can investigate and resolve the event from that trigger point.
