When implementing security controls, an information security manager must PRIMARILY focus on:

A. minimizing operational impacts.

B. eliminating all vulnerabilities.

C. usage by similar organizations.

D. certification from a third party.

Explanation:

Security controls must be compatible with business needs. It is not feasible to eliminate all vulnerabilities. Usage by similar organizations does not guarantee that controls are adequate. Certification by a third party is important, but not a primary concern.
