EBS: How to increase the timeout period for OWA and RWW

So you have discovered that the EBS’ Remote Web Workplace is the best thing since Captain Kirk. Users are using it everywhere. A frequent user request is to lengthen the timeout period before the application automatically logs out if the user is not active. As an administrator you have to realize that the reason this is in place is to protect the company and the indivudal employee. When you make this change you make it for everyone and therefore as an organization this decision has to come from the people who would fire you if information is lost or compromised.


An employee, Sharon is working from a remote location, in this case a school. Sharon uses a school computer to connect to RWW and to connect email, Sharepoint and some document folders. The power of RWW is that this is possible and that Sharon can do it when she needs it. Sharon is just about done the work she needs when a teacher asks for her help. Sharon thinks to herself, I have 30 minutes to get back to the computer to finish this off or it will log out. Sharon should log out before leaving her station.

She walks away to help the teacher leaving RWW logged in. Sharon is gone for 45 minutes and while she was gone Josh a good kid who is courious about computers walks by the computer and naturally glances at the screen. If Josh walks by at 27 minutes, he sees what ever Sharon was working on and has full access to email, document folders and all the power of RWW. Even good kids can be courious in this scenario. If Josh walks by at 33 minutes, RWW logged itself out at 30 minutes and the system is protected by the password. As it so happens Josh does walk by at 33 minutes and the system is logged out. Now think of the possibilities when you increase the timeout period for OWA and RWW.
