Which of the following is the MOST important goal of an information security program?

Optimizing resources is a goal of efficient management but secondary to the core objective of protecting information assets through risk reduction.

The most important goal of an information security program is to reduce risk factors by implementing controls that mitigate threats and vulnerabilities to an acceptable level. This focus ensures the protection of an organization's information assets and supports business objectives by minimizing potential harm from security incidents. All other security activities ultimately serve this overarching objective of risk reduction.

Managing controls is a means to achieve security, not the ultimate goal itself; controls are implemented to reduce risk.

Enhancing business decision making can be a benefit of a well-managed security program, but the core purpose is the protection of assets and operations, primarily through risk reduction.
