C.

Without the support of senior management, an information security program has little chance of survival.

A company's leadership group, more than any other group, will more successfully drive the program.

Their authoritative position in the company is a key factor.

Budget approval, resource commitments, and companywide participation also require the buy-in from senior management.

Senior management is responsible for providing an adequate budget and the necessary resources.

Security awareness is important, but not the most important factor.

Recalculation of the work factor is a part of risk management.

The MOST important factor in the successful implementation of an enterprise-wide information security program is the support of senior management (Option C).

Senior management plays a critical role in the success of an organization's information security program by providing the necessary resources, setting the tone at the top, and ensuring that the program is aligned with the organization's overall goals and objectives. Without the support of senior management, it can be challenging to secure the necessary resources, including funding, personnel, and technology, to implement an effective information security program.

Realistic budget estimates (Option A) are important for any project, including information security initiatives. However, even with a realistic budget, it can be challenging to implement an effective program without the support of senior management.

Security awareness (Option B) is critical for the success of any information security program, as employees are often the weakest link in an organization's security posture. However, senior management support is needed to establish a culture of security awareness and to ensure that the necessary training and awareness programs are in place.

Recalculation of the work factor (Option D) is not a well-defined term in the context of information security, and it is not clear how it relates to the successful implementation of an enterprise-wide information security program. Therefore, Option D is not the correct answer.

In summary, while realistic budget estimates, security awareness, and other factors are essential for the successful implementation of an enterprise-wide information security program, the support of senior management is the MOST important factor.
