Which of the following are advantages of adopting a Single Sign On (SSO) system?

A reduction in password fatigue for users because they do not need to know multiple passwords when accessing multiple applications

A reduction in network and application monitoring since all recording will be completed at the SSO system

A reduction in system administration overhead since any user login problems can be resolved at the SSO system

A reduction in overall risk to the system since network and application attacks can only happen at the SSO point
