Explanation:
Single sign-on (SSO) gives the administrator the ability to streamline user accounts and better control access rights. It, therefore, improves an administrator's ability to manage users and user configurations to all associated systems.
Incorrect Answers:
A: A disadvantage of SSO is that insufficient software solutions accommodate all major operating system environments. A mix of solutions must, therefore, be adapted to the enterprise's IT architecture and strategic direction.
B: A disadvantage of SSO is that considerable interface development and maintenance may be required, which could be costly.
C: SSO could be single point of failure and total compromise of an organization asset. This means that that if an attacker uncovers a credential set, the attacker would have access to every resource within the environment that the compromised account has access to.
