Question

1. Denial-of-service refers to the interruption of degradation of a data service or information access. Examples can packet sniffers for internet traffic.                                    True       False

2, Repudiation refers to the denial of a commitment or data receipt. This involves an attempt to back out of a contract or a protocol that requires the different parties to provide receipts acknowledging that data has not been received.                                  True       False

3. The default configuration of a system should have a conservative protection scheme. This states the fail-safe defaults principle.                                                                                            True       False

4, Each system or subsystem should operate with the minimum privileges necessary to function properly.                                                                                                                 True       False

5. Multiple systems or subsystems should be required to achieve access to restricted resources or have a program perform some action.                                                                   True       False

Explanation / Answer

1. False - A denial-of-service attack is a security event that occurs when an attacker takes action that prevents legitimate users from accessing targeted computer systems, devices or other network resources.Packet sniffers are used to diagnose Denial of Service.

2. True.

3. True.

4. False. Not the system / subsystem but the program and user of the programs operate with least set of priviledges necessary to function properly. Let me know is it is wrong . There is a possible ambiguithy in this . According to me priviledges are allocated to program and users not systems.

5. False.
