BS ISO/IEC 24762:2008 Information technology. Security techniques. Guidelines for information and communications technology disaster recovery services
BS ISO/IEC 24762 is the international standard that offers guidelines on the provision of ICT disaster recovery (ICT DR) services as part of business continuity management (BCM).
Information security management is the process by which management aims to achieve effective confidentiality, integrity and availability of information and service. When an organization implements an ISMS the risks of interruptions to business activities for any reason should always be identified. ISO/IEC 27001 and ISO/IEC 27002 include a control objective for information security aspects of business continuity management (refer to BS ISO/IEC 27002), the implementation of which will reduce those risks.
That control objective is supported by controls to be selected and implemented as part of the ISMS process. Business continuity management is an integral part of a holistic risk management process that safeguards the interests of an organization’s key stakeholders, reputation, brand and value creating activities through: identifying potential threats that may cause adverse impacts on an organization’s business operations, and associated risks; providing a framework for building resilience for business operations; providing capabilities, facilities, processes, action task lists, etc., for effective responses to disasters and failures.
In planning for business continuity, the fallback arrangements for information processing and communication facilities become beneficial during periods of minor outages and essential for ensuring information and service availability during a disaster or failure for the (complete) recovery of activities over a period of time. Such fallback arrangements may include arrangements with third parties in the form of reciprocal agreements, or commercial subscription services.
It specifies the requirements for implementing, operating, monitoring and maintaining ICT DR services and facilities, the capabilities which outsourced ICT DR service providers should possess and the practices they should follow.
There is also guidance on selecting a recovery site and advice on continuous service improvement.
The standard is especially suited to internal and outsourced ICT DR service providers of physical facilities and services as it describes the basic practices that ICT DR service providers should consider.
It covers the requirements that service providers should meet, recognizing that individual organizations may have additional requirements that are specific to them (which would have to be addressed in the agreements/contracts with service providers).
Examples of such organization requirements may include special encryption software and secured operation procedures, equipment, knowledgeable personnel and application documentation.
Such additional organization specific requirements, if necessary, are generally negotiated on a case-by-case basis and are the subject of detailed contract negotiations between organizations and their ICT DR service providers and are not within the scope of this International Standard.
