What happens when a  major data breach occurs? or a data center network switch failed? How will you act when a ransomware attacked your ERP server? What will you do if your system administrator suffered a heart attack? They are everyday potential disasters. Have you ever planned to face such disasters?

Practically, all risks associated with a business function cannot be totally eliminated. Despite every efforts, the residual risks can always remain, and incidents might still occur.

Unavoidable situations or unexpected threats and vulnerabilities may bypass  your security controls to effect confidentiality, integrity or availability of your information assets.  


Business Continuity Plan (BCP) objective is to restore business operations while recovering from a significant disruption after an incident. Business continuity policy defines what the top management wants to achieve with business continuity. ISO 22301 requires Business continuity policy to be compatible with the strategic direction of the organization.

BCP is contingency planning aims to prepare for major incidents and disasters by making plans, assigning responsibilities and allocating resources resources to minimize the adverse consequences and recover fast to the normal state.


BCP aimed to keep important business processes running. It directs making supporting information systems operational and available to business  functions. The measures may involve recovery from backups, redundancy with automated fail over, ensure off-site operations, having alternative suppliers,  fallback equipment and networks etc. BCP require IT infrastructure and processes in operation despite disasters to recover and resumption of critical business functions.This may include planning for office relocation, manual processing, online working, third party arrangements etc.  The process of Disaster Recovery may  involve manual restoring of data, use of standby equipment, alternative  communications facilities etc. 


Incident Respinse, Disaster Recovery, and Crisis Management

are key processes in BCP. Incident Response (IR) evaluates events and responds to  information security incidents.  It's a continues process dealing with  minor incidents to update systems and controls to improve resilience. 


Disaster Recovery is a plan to recover affected functions. Disaster Recovery Plan (DRP) is activated anytime as a result of an incident. 

ISO 27001 Annex A.17.1 provides controls  for information security continuity. It’s an important part of your  ISMS) for ISO 27001 certification. 


Crisis Management (CM) is mainly related to health and safety issues. CM include preliminary assessment of the situation and liaison with emergency services. 

Establishing of Information Security Continuity, require documenting and maintaining relevant processes, procedures, physical, administrative and physical controls to mitigate  a disruptive situation. The documentation should include BC activities and owners, their responsibilities, timescales, mitigating measures, communications strategy, resources including a management structure with authority to manage the BC to make business return to normality.


Each individual organization must determine how often to test its BCP, but it should be tested at predefined intervals as well as when significant changes happen within the business environment. Regular internal audits must verify the information security continuity controls in order to test and ensure that they are effective during incidents.  During ISO 27001 accreditation process an auditor will seek evidence of plans and results of periodic testing of BC controls.
