Single sign-on technologies
A) Ensure that the user has the same username and password on all systems
B) Have no single point of failure
C) Allow a user to authenticate once and obtain access to all authorized resources
D) Allow nodes in an insecure network to securely identify themselves to each other using tokens

Question

Quizplus · Accepted Answer

Single sign-on technologies allow a user to authenticate once and obtain access to all authorized resources, without having to log in separately to each system or application. This enhances user convenience and productivity by reducing the need for multiple sets of login credentials.

A) is incorrect because single sign-on technologies do not ensure that the user has the same username and password on all systems. In fact, different systems and applications may have different authentication mechanisms and credentials.

B) is partially incorrect because some single sign-on technologies may have a single point of failure, such as the central authentication server. However, many modern implementations of single sign-on use distributed or federated architectures to eliminate single points of failure and improve reliability.

D) is unrelated to single sign-on technologies and describes a different security mechanism called mutual authentication using tokens, which allows nodes in an insecure network to securely identify themselves to each other without sharing credentials.
