= A multinational organization is required to follow governmental regulations with different security requirements at each of its operating locations. This means that the CISO has to deal with multiple and diverse legal, regulatory, and compliance issues across different jurisdictions and markets. The CISO should be most concerned with developing a security program that meets global and regional requirements, such as ISO/IEC 27001, NIST CSF, PCI DSS, GDPR, etc. These standards provide a framework for establishing, implementing, maintaining, and improving an information security management system (ISMS) that aligns with the organization's business objectives and risk appetite. The CISO should also ensure that the security program is consistent and coherent across all operating locations, and that it complies with the specific regulations of each location. Therefore, option A is the most appropriate answer. References = CISM Review Manual 15th Edition, page 255; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, QID 234.
In this scenario, the chief information security officer (CISO) should be most concerned with developing a security program that meets the global and regional requirements of the organization. This includes considering the different legal and regulatory requirements of each operating location, and designing a security program that meets all of these requirements. The CISO should also ensure effective communication with local regulatory bodies to ensure compliance and understanding of the security program. Additionally, the CISO should use industry best practices and defined security policies and standards to ensure the program meets all applicable requirements.

Ensuring current documentation of security processes is the best way to support information security management in the event of organizational changes in security personnel. Documentation of security processes provides a clear and consistent reference for the roles, responsibilities, procedures, and standards of the information security program. It helps to maintain the continuity and effectiveness of the security operations, as well as the compliance with the security policies and regulations. Documentation of security processes also facilitates the knowledge transfer and training of new or existing security personnel, as well as the communication and collaboration with other stakeholders. By ensuring current documentation of security processes, the information security manager can minimize the impact of organizational changes in security personnel, and ensure a smooth transition and alignment of the security program.

= In an organization with a rapidly changing environment, the information security risk landscape may also change frequently due to new threats, vulnerabilities, impacts, or controls. Therefore, the information security manager should ensure that the risk acceptance decisions made by the business management are periodically reviewed to verify that they are still valid and aligned with the current risk appetite and tolerance of the organization. The rationale for acceptance should be documented and updated as necessary to reflect the changes in the risk environment and the business objectives. The information security manager should also monitor the accepted risks and report any deviations or issues to the business management and the senior management.

Risk management is the most important factor for the effectiveness of an information security program, as it provides a systematic and consistent approach to identify, assess, treat, and monitor the information security risks that could affect the organization's objectives. Risk management also helps to align the security program with the business strategy, prioritize the security initiatives and resources, and communicate the value of security to the stakeholders.

Transport Layer Security (TLS) is a protocol that provides encryption, authentication, and integrity for data transmitted over the Internet. TLS protects the confidentiality of data by encrypting it before sending it and decrypting it after receiving it. TLS also verifies the identity of the communicating parties by using certificates and prevents data tampering by using message authentication codes.
