C

Answer to Question 2

1. Physical security refers to securing the computer facility, its equipment, and software through physical means. It can include controlling access to the computer room by means of machine readable badges, biometric systems, or a human sign-in/sign-out system, as well as using closed circuit television cameras to monitor computer areas, backing up data frequently, and storing backups in a fireproof, waterproof area, often at a secure off-site location.

2. Logical security refers to logical controls in the software itself. The logical controls familiar to most users are passwords or authorization codes of some sort.

3. The behavioral security refers to the expectations of an organization that are implicit in its policy manuals and even on signs posted in work rooms and lunch rooms. The behavior that organization members internalize, however, is also critical to the success of security efforts.
