In response to the growing importance of Business Continuity Management (BCM), a number of best-practice guidelines have been developed to provide a standardized approach for the development of a BCM strategy.
An important reference is this context is the British Standard BS 25999. It is an internationally accepted standard based on the idea of a “Business Continuity Management System” (BCMS): Unlike a business continuity plan that focuses merely on the recovery from an interruption, a BCMS also comprises the development and implementation of policies and procedures to protect all assets of an organization. It provides controls to prevent the risk of an interruption occurring and recommends appropriate responses to an interruption. However, BS 25999 does not provide specific controls to implement.
On the basis of BS 25999, the German Federal Office for Information Security (BSI) developed its “BSI-Standard 100-4”. In contrast to BS 25999, BSI-Standard 100-4 does not only define an abstract approach, but also provides detailed implementation procedures.
