Using Single Sign On Can Raise Network Security Concerns

Using single sign on methods can create network security concerns for organizations. This method of logging onto a local computer and connecting to a network, applications, and other resources only requires a single log in. The user simply enters their user name and password once, and can open and use everything they have access to, without having to enter it again.

Ways to Implement Security When Using Single Sign on Methods

There are ways to implement security when organizations want to continue to use single sign on methods. One solution is to use USB tokens, where users have to insert the USB device into the computer prior to logging into the computer. During the log in process, the token uses cryptographic information to determine which resources the user is allowed to access. Without the token, the user will be unable to log onto the computer or gain access to applications or network resources.
