TRUE/FALSE QUESTIONS:
T F 1. Threats are attacks carried out.
T F 2. Computer security is protection of the integrity, availability, and
confidentiality of information system resources.
T F 3. Data integrity assures that information and programs are changed only
in a specified and authorized manner.
T F 4. Availability assures that systems works promptly and service is not
denied to authorized users.
T F 5. The “A” in the CIA triad stands for “authenticity”.
T F 6. The more critical a component or service, the higher the level of
availability required.
T F 7. Computer security is essentially a battle of wits between a perpetrator
who tries to find holes and the administrator who tries to close them.
T F 8. Security mechanisms typically do not involve more than one particular
algorithm or protocol.
T F 9. Many security administrators view strong security as an impediment to
efficient and user-friendly operation of an information system.
T F 10. In the context of security our concern is with the vulnerabilities of
system resources.
T F 11. Hardware is the most vulnerable to attack and the least susceptible to
automated controls.
T F 12. Contingency planning is a functional area that primarily requires
computer security technical measures.
T F 13. X.800 architecture was developed as an international standard and
