Description:
Invalidate any existing session identifiers prior to authorizing a new user session.
Phase: Architecture and Design
Description:
For platforms such as ASP that do not generate new values for sessionid cookies, utilize a secondary cookie. In this approach, set a secondary cookie on the user’s browser to a random value and set a session variable to the same value. If the session variable and the cookie value ever don’t match, invalidate the session, and force the user to log on again.
