Which of the following measures how your program is supporting an organization's overall security program, the mission, and the interests of senior leaders?

The measure that assesses how a program supports an organization's overall security program, mission, and the interests of senior leaders is strategic metrics. Strategic metrics are designed to evaluate long-term objectives and align the security initiatives with the organization's broader goals. These metrics help demonstrate the effectiveness of security efforts in contributing to the overall mission and priorities of the organization and provide insights that are crucial for senior leadership in decision-making.

In contrast, operational metrics focus on day-to-day operational effectiveness and efficiency, tactical metrics are concerned with short-term projects and specific outcomes, while performance metrics encompass various types of data that measure an organization’s progress towards its objectives, but may not directly align with strategic direction. Thus, the emphasis on the organization's mission and long-term objectives makes strategic metrics the most appropriate choice in this context.
