Which of the following is the PRIMARY safeguard for securing
software and data within an information processing facility?
A. Security awareness
B. Reading the security policy
C. Security committee
D. Logical access controls
Answer / guest
Answer: D
To retain a competitive advantage and to meet basic business
requirements, organizations must ensure the integrity of the
information stored on their computer systems, preserve the
confidentiality of sensitive data and ensure the continued
availability of their information systems. To meet these
goals logical access controls must be in place. Awareness
(choice A) itself does not protect against unauthorized
access or disclosure of information. Knowledge of an
information systems security policy (choice B), which should
be known by the organization's employees, would help to
protect information, but would not prevent the unauthorized
access of information. A security committee (choice C) is
key to the protection of information assets, but would
address security issues within a broader perspective.
