Control 5.5 ensures appropriate procedures exist for contacting authorities when needed, such as reporting incidents.

Control 7.9 Security of assets off-premises belongs to the physical controls category in ISO/IEC
27002:2022.

Establishing and maintaining contact with special interest groups is a good practice under ISO/IEC 27002.
Organizations benefit from timely information about security threats, vulnerabilities, attack trends, advisories, defensive practices, and sector-specific risks. Special interest groups can include industry associations, information sharing and analysis centers, professional forums, security communities, vendor groups, government-supported networks, and trusted peer organizations. This supports threat intelligence, incident readiness, vulnerability management, and continual improvement. Option A is incorrect because avoiding information exchange would isolate the organization and weaken its ability to anticipate emerging threats.
Option B is too restrictive because authorities may be important contacts, but they are not the only legitimate or useful source of security information. ISO/IEC 27002 encourages appropriate contact with relevant groups while still requiring responsible handling of shared information, confidentiality, trust boundaries, and legal obligations. The security value lies in turning external knowledge into better internal controls, awareness, monitoring, and response. Therefore, option C is the verified answer.

Segregation of duties reduces opportunities for unauthorized or unintentional modification/misuse by separating conflicting responsibilities.

When an employee leaves the organization or changes roles, their information security responsibilities should be identified and transferred appropriately. ISO/IEC 27002 emphasizes that responsibilities must remain clear throughout the employment lifecycle, including changes and termination. Security duties cannot simply disappear when a person leaves a role. Examples include ownership of assets, approval duties, incident response responsibilities, privileged access administration, supplier contact responsibilities, classification decisions, or operational security tasks. The organization should determine which responsibilities the employee holds, remove responsibilities that no longer apply, revoke or adjust access rights, and assign continuing responsibilities to another competent person. Option B is too limited because documenting responsibilities in a termination policy does not ensure that active duties are transferred. Option C is incorrect because outsourcing is not required and may introduce additional supplier risk. The central ISO/IEC 27002 principle is continuity of accountability: responsibilities must be maintained even when personnel move, leave, or change duties. This also supports least privilege because access and responsibilities should match the current role.
