The primary purpose for the long-term plan for the information security program is to ensure controls align with security needs. This is because the long-term plan provides a strategic vision and direction for the information security program, and defines the goals, objectives, and initiatives that support the organization’s mission, vision, and values. The long-term plan also helps to identify and prioritize the security risks and opportunities that may arise in the future, and to align the information security controls with the changing business and technology environment. The long-term plan also facilitates the allocation and optimization of the resources and budget for the information security program, and enables the measurement and evaluation of the program’s performance and value.
