What is an "user session" in Splunk ES?

In Splunk Enterprise Security, a "user session" refers specifically to a login instance by a user. This concept is integral for tracking user activity within the system and for maintaining security protocols. Each time a user logs into the Splunk ES environment, a session is created, which allows the system to monitor their actions and the data they access during that time.

This is important for auditing purposes, as it enables security analysts to trace specific actions back to individual users, thereby enhancing accountability and aiding in incident response. The user session encapsulates the interaction of that particular user with the application from the moment they log in until they log out or until the session expires, which can include all data usage and actions taken within that timeframe.

Understanding user sessions is critical for managing security policies and ensuring compliance with data access standards.
