Question 1. Question :
(TCO A) What are the three types of user authentication?
Name three examples of each type of authentication.
Student Answer: The first type of authentication is physical proof. Meaning the person
is there physically. The second type of authentication is in pin or
password verification. This is someone who has a badge and/or pin
number to gain access to certain areas that other are not allowed to.
The third authentication is documentation. This could be a drivers
licence or other proof of documentation that affirms that person is
genuine and is allowed to gain access to that area. Along those same
lines the other way to determine user authentication is Password
authentication where the person has a pin or password to gain access.
The second being Kerberos Authentication, where a ticket is given to
the user to gain access and an authenticator that verify s legitimacy
of the user. The third being SSL, where when the connection is
established, the server sends its certificate and once it is
authenticated retrieves the client's certificate. The client then gives its
user name before it gains access. Authentication. (2014, September

, Question 2. Question :
(TCO A) List and define five desirable qualities in a process
designed to
evaluate the trustworthiness of an operating system.
Student Answer: The five areas that are most desirable in determining the
trustworthiness of an operating system are; "1. Suitability of
functionality: whether the chosen functions implement the desired
security features. 2. Binding of functionality: whether the chosen
functions work together synergistically. 3. Vulnerabilities: whether
vulnerabilities exist either in the construction of the TOE or how it will
work in its intended environment. 4. Ease of use 5. Strength of
mechanism: the ability of the TOE to withstand direct attack."
