Asking a user for I&A over and over again is annoying, so the system needs a means of associating an action automatically with a user that was previously authenticated. After a long period of inactivity, the system needs to re-authenticate a user to prevent misuse and overhead. In other words, the system should automatically sign off inactive users.

Introduce a session object that holds all user-relevant shared data. Security information related to the user, especially, is kept in the session object. In addition to the session object that holds the values, the system needs to associate every action a user makes with this session. This can be either implicitly, such as associating every action coming over the user s connection with the session, or explicitly with an identifier like a session cookie that is sent to a user s browser by an on-line store site. A system s CHECK POINT (287) is the usual place to instantiate the session object and set up its initial values. For systems with access control, the session object can be used to obtain access permissions at sign-on and cache them, to avoid multiple queries to an external database. In addition, the session object can provide a scratch-pad area to allow different system components to share arbitrary data about the user between different actions within a log-on period. For example, classic mainframe systems provide a so-called terminal control block that can be used by different interactive transaction programs to share data, such as the last values entered in a form. This allows otherwise independent transaction programs to be chained easily on behalf of the user. Web applications use cookies to share data for a given user. Often a MANAGER [Som98] is used to keep track of active session objects and controls their life cycle. This MANAGER can also be used to provide the mapping of external session identifiers, such as those stored in a session cookie, to the session object and its data. Furthermore, it can collect obsolete sessions that were abandoned by their users.

The following diagram shows the component relationships assuming that there is a MANAGER. The CHECK POINT (287) uses the MANAGER to associate a Session object with the user. Later, the components accessed by the user rely on the associated Session object to access the user s access rights and further information. The Manager class uses the timestamp to keep track of stale session objects, and forces the user to re-authenticate if a session is either used for too long without authentication, or if it has not been used for a longer time.

The following scenario shows a simplified interaction, in which a user logs into the system via the CHECK POINT (287). The CHECK POINT (287) uses the MANAGER to obtain a new Session object for the user. The manager does not return the object directly, but instead returns an external session identifier to be used by the user or CHECK POINT (287) for later reference. This scenario assumes that the user explicitly provides his session identifier instead, as would occur with a Web application s session cookie. Other systems can provide an implicit association of a user with his session object this is not shown here. Later on the user interacts with a system component, providing his session identifier for reference. The system component authorizes the user by asking the MANAGER for the underlying session object and checking the user s data stored there. When the user logs off at the CHECK POINT (287), the MANAGER deletes the Session object belonging to the user, invalidating the corresponding session identifier, which no longer can be used. See figure on page 301.
