1. Right Answer: C
Explanation: Out-of-band channels are useful when it is necessary, for confidentiality, to break a message into two parts that are then sent by different means. Digital signatures only provide nonrepudiation. Reverse lookup translation involves converting; in Internet Protocol (IP) address to a username. Delivery path tracing shows the route taken but does not confirm the identity of the sender.
2. Right Answer: A
Explanation: Mandatory access controls restrict access to files based on the security classification of the file. This prevents users from sharing files with unauthorized users.Role-based access controls grant access according to the role assigned to a user; they do not prohibit file sharing. Discretionary and lattice-based access controls are not as effective as mandatory access controls in preventing file sharing. A walled garden is an environment that controls a user's access to web content and services. In effect, the walled garden directs the user's navigation within particular areas, and does not necessarily prevent sharing of other material.
3. Right Answer: B
Explanation: Signature-based intrusion detection systems do not detect new attack methods for which signatures have not yet been developed. False positives are not necessarily any higher, and spoofing is not relevant in this case. Long duration probing is more likely to fool anomaly-based systems (boiling frog technique).
4. Right Answer: D
Explanation: Data owners approve access to data and determine the degree of protection that should be applied (data classification). Administering database security, making emergency changes to data and migrating code to production are infrastructure tasks performed by custodians of the data.
5. Right Answer: B
Explanation: System users, specifically the user acceptance testers, would be in the best position to note whether new exposures are introduced during the change management process. The system designer or system analyst, data security officer and operations manager would not be as closely involved in testing code changes.
