TRUE/FALSE
1. In a computerized environment, the audit trail log must be printed onto paper document.
2. Disguising message packets to look as if they came from another user and to gain access to the host’s network is called spooling.
3. A formal log-on procedure is the operating system’s last line of defense against unauthorized access.
4. Computer viruses usually spread throughout the system before being detected.
5. A worm is software program that replicates itself in areas of idle memory until the system fails.
6. Viruses rarely attach themselves to executable files.
10. Operating system controls are of interest to system professionals but should not concern accountants and auditors.
11. The most frequent victims of program viruses are microcomputers.
13. Operating system integrity is not of concern to accountants because only hardware risks are involved.
14. Audit trails in computerized systems are comprised of two types of audit logs: detailed logs of individual keystrokes and event-oriented logs.
15. In a telecommunications environment, line errors can be detected by using an echo check.
16. Firewalls are special materials used to insulate computer facilities
17. The message authentication code is calculated by the sender and the receiver of a data transmission.
18. The request-response technique should detect if a data communication transmission has been diverted.
19. Electronic data interchange translation software interfaces with the sending firm and the value added network.
20. A value added network can detect and reject transactions by unauthorized trading partners.
21. Electronic data interchange customers may be given access to the vendor's data files.
22. The audit trail for electronic data interchange transactions is stored on magnetic media.
23. A firewall is a hardware partition designed to protect networks from power surges.
