Because over the years more and more activities have become dependent upon information and communication technologies (ICT), and ICT failures are becoming more critical, it is natural to expect the spread of literature dealing specifically with this issue. In this context, the ISO 27031 standard approaches how to use the PDCA (Plan-Do-Check-Act) cycle to put into place a systematic process to prevent, predict, and manage ICT disruption incidents that have the potential to disrupt ICT services. By doing so, this standard helps to support both business continuity management (BCM) and information security management (ISM). By its nature, ISO 27031 is a perfect standard to resolve the control A.17.2.1 from ISO 27001. Many organizations struggle to define the best method to meet business expectations regarding information technology (IT) recovery. ISO 27031 provides guidance to business continuity and IT disaster recovery professionals on how to plan for IT continuity and recovery as part of a more comprehensive business continuity management system (BCMS). The standard helps IT personnel identify the requirements for Information and Communication Technology (ICT) and implement strategies to reduce the risk of disruption, as well as recognize, respond to and recover from a disruption to ICT. ISO 27031 introduces a management systems approach to address ICT in support of a broader business continuity management system, as described in ISO 22301. ISO 27031 describes a management system for ICT readiness for business continuity (IRBC). An IRBC is a management system focused on IT disaster recovery. IRBC uses the same Plan-Do-Check-Act (PDCA) model as the business continuity management system described in ISO 22301. The objective of IRBC is to implement strategies that will reduce the risk of disruption to ICT services as well as respond to and recover from a disruption. Business continuity and IT professionals will find the use of the PDCA model very familiar but with necessary changes to support recoverability of ICT based on business requirements and expectations. ISO 27031 defines the information and communication technology (ICT) requirements for Business Continuity (BC) program that supports the mandate for an infrastructure that supports business operations when an event or incident with its related disruptions affects the continuity of critical business functions. This includes security of crucial data as well as enterprise operations. This course focuses on the technical and procedural issues surrounding ICT Service Continuity & Disaster Recovery (DR).
