The Flow Collector can use statistical sampling to collect and store network flow data in the JSA database. The Event Collector collects information from various sources including syslog, SNMP, NetFlow, and BGP FlowSpec. Both the Flow Collector and the Event Collector parse logs to extract useful information from the logs.

The solution that enables you to create security policies that include user and group information is JIMS (Juniper Identity Management Service). JIMS collects and maintains a large database of user, device, and group information from Active Directory domains or syslog sources, and enables SRX Series devices to rapidly identify thousands of users in a large, distributed enterprise. With JIMS, you can create security policies that include user and group information, and enforce user-based access control policies to protect network resources.
