A.17.1 Information Security Continuity

Its objective is the continuity of information security should be integrated into the business continuity management processes of the organization.

A17.1.1 Planning Information Security Continuity

Control – In adverse circumstances, e.g. during a crisis or a catastrophe, the company will determine the information security standards and consistency of information security management.

Implementation Guidance- An organization should assess whether the continuity of security is captured in the management process of business continuity or in the disaster recovery process. In business continuity preparation and disaster recuperation, information security standards will be determined.

The Information Security Management should assume that information security requirements remain the same in unfavorable situations as normal operational conditions without a formal business continuity and disaster recovery plan. In order to define security criteria related to adverse circumstances, an organization may also carry out a business effect analysis for information security issues.

Other Information- It is advised to capture the security aspects of information within the standard business continuity or disaster recovery management business impact analysis to minimize the time and expense of an external business impact analysis for information security. That means, in business continuity management or disaster recovery management systems, the criteria for continuity information protection are specifically formulated.

A.17.1.2 Implementing Information Security Continuity

Control- In order to ensure the necessary degree of consistency of information security to adverse circumstances, the company should define, document, execute, and maintain processes, procedures, and controls.

Implementation Guidance- An organization should make sure that:

  • Adequate management structure is in place with the authority, experience, and competence to plan, mitigate and respond to disruptive events with the workforce necessary;
  • Incident response personnel are nominated for incident management and information security with the necessary responsibility, authority, and competence;
  • It develops and approves the documented plans, response and recovery procedures detailing how the organizations manage a disruptive event and maintain their security of information to a pre-set level based on the information security continuity objectives approved through management.

The organization should establish, record, execute, and maintain the information security continuity requirements:
  • Controlling of information security, processes and support systems and equipment, as well as business continuity or disaster recovery process.
  • Processes, procedures and changes in implementation in an adverse situation in order to maintain existing information security controls;
  • Compensating information security management mechanisms that can not be enforced under adverse circumstances.

“Continuous improvement is better than delayed perfection”
– Mark Twain

Other Information- Different processes and procedures may be described within the context of business continuity or disaster recovery. Information that is stored inside or inside specific information systems to help these processes and procedures should be covered. Therefore, information security professionals will be active in the development, implementation, and management of business continuity and systems and procedures for disaster recovery.

In an adverse situation, information security checks carried out should still operate. In the absence of effective information security controls, other controls are needed to ensure appropriate information security, to be developed, enforced, and maintained.
