A Simple Form of Authentication Is Single Sign On

Single sign on [1] is a simple form of authentication used by some organizations. This method stores a person’s user name and password after it has been entered. Anytime authentication is required for accessing a new resource or application, the system uses the stored information. While this method makes it easier for users to gain access, it does come with its own risks.

Ways in Which Unauthorized Access Can Occur with Single Sign On

The primary concern of using single sign on authentication is users gaining unauthorized access to systems and resources. There are different ways in which this can occur. For example, one person leaves their computer on and signed in, all of the time, even when they are out of the office. Anyone could sit down at the computer and access the systems and resources the employee uses. Another way unauthorized access occurs is when employees share their user names and passwords with one another.
