When you modify a security policy on the SRX Series device, the default behavior is that the existing sessions that match the policy will continue unchanged. This means that the policy modification will only affect new sessions that are initiated after the change. However, you can change this behavior by using the clear-policy-session command, which will clear all the sessions that match the modified policy and force them to re-evaluate the new policy.Reference:=JNCIS-SEC Certification,Open Learning - Security, Specialist (JNCIS-SEC),Security Policies (Advanced)

To solve the issue of out of order event log timestamps on your JIMS server, you should enable time synchronization on the domain controllers. JIMS (Juniper Identity Management Service) is a Windows service that collects user, device, and group information from Active Directory domains or syslog sources and provides it to SRX Series devices and CSO for identity-based security policies. JIMS relies on the timestamps of the event logs generated by the domain controllers to track user logins, logouts, and IP address changes. If the domain controllers have different or inaccurate clocks, the event logs may have out of order or incorrect timestamps, which can cause JIMS to miss or misinterpret some events and affect its accuracy and performance. Therefore, you should ensure that all the domain controllers in your network are synchronized with a reliable time source, such as an NTP server or a Windows Time service.Reference:=Juniper Identity Management Service User Guide,Juniper Identity Management Service Feature Guide,Configure JIMS Collector to Get Microsoft Event Logs,Considerations for timestamps in centralized logging platforms

The early-ageout configuration specifies the timeout value, in seconds, that will be applied once the high-watermark value is met. The high-watermark configuration specifies the percentage of how much of the session table can be allocated before applying a more aggressive age-out timer. This ensures that the session table does not become full and cause traffic issues, and also ensures that existing flows are aged out quickly when the table begins to get close to being full.

The two configurable features on Juniper Secure Analytics (JSA) that can be used to ensure that alerts are triggered when matching certain criteria are events and tests. Events refer to the collection of data from different sources, while tests are used to define the criteria for which an alert is triggered. For example, you can use events to collect data from a firewall and tests to define criteria such as IP address, port number, and the type of traffic. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to configure these features on JSA.
