ISO 18788 - Clause 4.3 - SOMS Determining the scope of the security operations management system
ISO 18788 Clause 4.3 addresses the requirement for determining the scope of the Security Operations Management System (SOMS). This clause is essential for defining the boundaries and coverage of the security management system within an organization. Here's an explanation of the key elements of this clause:
Clause 4.3 - Determining the Scope of the Security Operations Management System (SOMS):
-
Scope Definition: The organization must clearly define and document the scope of its SOMS. This definition should outline the extent of security operations, functions, processes, and activities that are covered by the SOMS. It sets the boundaries for what the SOMS encompasses.
-
Consideration of External and Internal Factors: When determining the scope, the organization should consider both internal and external factors that can influence security operations. These factors may include legal and regulatory requirements, organizational goals, stakeholder expectations, the organization's size and structure, and the nature of its security-related activities.
-
Inclusion and Exclusion: The scope should explicitly state what is included within the SOMS and, equally important, what is excluded. Items excluded from the scope should be justified, and the reasons for exclusion should be documented.
-
Alignment with Organizational Objectives: The scope of the SOMS should align with the organization's overall objectives and strategic direction. It should support the organization's mission and goals, especially in relation to security and risk management.
-
Communication: Once the scope is defined, it should be communicated effectively within the organization. All relevant personnel, including security management and staff, should understand the scope and its implications.
-
Documented Information: Document the defined scope and maintain it as documented information within the SOMS documentation. This ensures that the scope is accessible to those who need it for reference and decision-making.
-
Periodic Review: The scope should not be static. It should be periodically reviewed and updated to reflect changes in the organization's security operations, external factors, or strategic priorities.
-
Consistency with ISO 18788: Ensure that the scope aligns with the requirements of ISO 18788 and supports the organization's commitment to security management best practices.
Defining the scope of the SOMS is a fundamental step in establishing an effective security management framework. It provides clarity about what the SOMS covers and helps the organization allocate resources, establish objectives, and manage risks in a focused and systematic manner. Additionally, it facilitates communication with internal and external stakeholders regarding the organization's security management efforts.
Specific procedures and documentation related to scope determination should be developed and implemented in accordance with the organization's unique needs and the requirements of ISO 18788.
