1. Right Answer: B
Explanation: A system downtime log can be very helpful to an IS auditor when determining the efficacy of a systems maintenance program.
2. Right Answer: A
Explanation: Concurrency controls are used as a countermeasure for potential database corruption when two processes attempt to simultaneously edit or update the same information.
3. Right Answer: B
Explanation: A long asymmetric encryption key (public key encryption) increases encryption overhead and cost. All other answers are single shared symmetric keys.
4. Right Answer: A
Explanation: Worms are malicious programs that can run independently and can propagate without the aid of a carrier program such as email.
5. Right Answer: C
Explanation: Identifying network applications such as mail, web, or FTP servers to be externally accessed is an initial step in creating a proper firewall policy.
Explanation: A system downtime log can be very helpful to an IS auditor when determining the efficacy of a systems maintenance program.
