   An important part of your role with the Prisma Access Browser is analyzing events, and looking for patterns and anomalies in user behavior. Whenever you notice unexpected or unusual activity, you need to see if you need to tune the rules to meet the needs and requirements of the end users. The Prisma Access Browser allows you to search and filter the events to discover and analyze user behavior patterns. At the top of the screen, you can search for specific events using specific data to help find a particular event.
