AOnce a user obtains access to the system through the initial log-on, he has to logout from all other systems
BOnce a user obtains access to the system through the initial log-on, they only need to logon to some applications.
CThe initial logon process is cumbersome to discourage potential intruders.
DOnce an individual obtains access to the system through the initial log-on, they have access to all resources within the environment that the account has access to.
✓ Correct answer: D. Once an individual obtains access to the system through the initial log-on, they have access to all resources within the environment that the account has access to.Single Sign-On is a distributed Access Control methodology in which a user only has to authenticate once to have access to all major and secondary network domains. <br/><br/>When the individual needs extra resources, they would not be asked to re-authenticate. The security concern this raises is that if a fraudster is able to compromise those credentials, they will also have access to all the resources that the account has access to. Because they are distractors, all of the other responses are wrong.
