Single sign-on (SSO): Concepts, Methods and Frameworks

Single sign-on (SSO) is a method of access control that enables a user to log in once and gain access to the resources of multiple software systems without being prompted to log in again. Single sign-off is the reverse process whereby a single action of signing out terminates access to multiple software systems.

As different applications and resources support different authentication mechanisms, single sign-on has to internally translate to and store different credentials compared to what is used for initial authentication.

As IT systems proliferate to support business processes, users and system administrators are faced with an increasingly complicated interface to accomplish their job functions. Users typically have to sign-on to multiple systems, necessitating an equivalent number of sign-on dialogues, each of which may involve different usernames and authentication information. System administrators are faced with managing user accounts within each of the multiple systems to be accessed in a co-ordinated manner in order to maintain the integrity of security policy enforcement.
