1. Right Answer: C
Explanation: Screensaver passwords are an effective control to implement as a countermeasure for the vulnerability of data entry operators potentially leaving their computers without logging off.
2. Right Answer: C
Explanation: ISPs can use access control lists to implement inbound traffic filtering as a control to identify IP packets transmitted from unauthorized sources.
3. Right Answer: B
Explanation: A key distinction between encryption and hashing algorithms is that hashing algorithms are irreversible.
4. Right Answer: A
Explanation: Data diddling involves modifying data before or during systems data entry.
5. Right Answer: B
Explanation: When evaluating biometric access controls, a low equal error rate (EER) is preferred. EER is also called the crossover error rate (CER).
