Workarounds and Mitigations
HTTP session logout timeout
When the browser HTTP session for a Control Center user times out, the user is logged out. However, someone can possibly intercept and override the logout timeout. To avoid this override, configure the com.ibm.ws.security.web.logoutOnHTTPSessionExpire property in WebSphere Application Server. For more information about this property, see the WebSphere Application Server documentation.
