In today’s article at Kimova AI ISO 27001 auditing series, we focus on People Control A.6.5: Responsibilities After Termination or Change of Employment, which addresses how an organization should handle information security responsibilities when employees leave or their role changes. Ensuring proper procedures are in place during these transitions helps protect sensitive information and minimizes the risk of unauthorized access.

Control A.6.5: Responsibilities After Termination or Change of Employment

This control ensures that when an employee departs or changes roles, their access to the organization’s sensitive information is effectively managed. Failure to revoke access promptly or clarify information security responsibilities can lead to data breaches or misuse of organizational resources.

Key Aspects of Control A.6.5

  1. Revocation of Access Rights
    • Explanation: When an employee leaves or changes roles, their access to the organization’s systems and data should be immediately revoked to prevent unauthorized use.
    • Example: A departing IT administrator’s system credentials are immediately deactivated upon their last working day, preventing any further access to the company’s servers and data.
  2. Return of Organizational Assets
    • Explanation: Employees should return all company assets, including devices, access cards, and any confidential information in their possession, before their employment ends.
    • Example: An employee hands in their company-issued laptop and key card during their exit interview, ensuring that no physical access to company systems or facilities remains.
  3. Post-Employment Confidentiality Obligations
    • Explanation: Former employees should continue to respect the confidentiality of the information they had access to during their employment. This includes nondisclosure agreements (NDAs) that remain in effect after they leave the organization.
    • Example: A former marketing manager is legally obligated to not disclose any proprietary marketing strategies or client information they had access to during their tenure.
  4. Clear Communication of Security Responsibilities
    • Explanation: Employees must be made aware of their information security responsibilities as part of their departure or role change process. This includes understanding any restrictions on accessing or using organizational data after leaving.
    • Example: An HR representative explains the company’s data retention policies to a departing employee, emphasizing that accessing any remaining company files post-employment is strictly prohibited.
  5. Transfer of Responsibilities
    • Explanation: When an employee changes roles, there should be a proper handover of their information security responsibilities to the new person in charge to maintain continuity and avoid any gaps in security.
    • Example: When a project manager is promoted to a new role, they ensure that all project files and security credentials are passed on to their successor.
  6. Exit Interviews and Security Debriefs
    • Explanation: Exit interviews provide a valuable opportunity to remind employees of their ongoing information security responsibilities and gather feedback on the organization’s security policies.
    • Example: During the exit interview, an employee is asked to review and sign a document confirming their understanding of post-employment confidentiality obligations.
  7. Updating Access Control Lists
    • Explanation: The organization’s access control lists should be regularly updated to reflect changes in employment status, ensuring that former employees or those in new roles do not retain inappropriate access.
    • Example: Following the departure of a finance executive, the IT team updates the company’s access control lists to remove their access to the financial system.
  8. Ensuring Compliance with Legal and Regulatory Obligations
    • Explanation: The organization must ensure that the termination or change of employment process complies with legal and regulatory requirements, especially regarding personal data and information retention policies.
    • Example: A European company ensures that it complies with GDPR regulations by deleting an ex-employee’s personal data from its databases, except for any records required for legal purposes.

Conclusion

People Control A.6.5: Responsibilities After Termination or Change of Employment is critical to ensuring that sensitive data remains secure even when employees leave the company or transition to a new role. Implementing this control helps reduce the risk of data leaks or unauthorized access after employment ends.
