Environment

Sentinel Log Manager 1.1.0.x

Situation

At times there are known security vulnerabilities that may exist in third party products that ship with Sentinel Log Manager thus necessitating an update for your Security Identity Event Management, (SIEM), system. This documents is intended to guide you through the update of Sun's JRE on your existing Sentinel Log Manager system. While this has been officially tested for 1.1.0.2, it should apply to future releases as well. As always, its a good idea to test these steps in a lab environment before applying to your production system.
