Detailed background on CISSP exam Domain 7, covering business continuity and disaster recovery. Business continuity and disaster recovery planning: Management leadership, goals and requirements, business impact analysis, team building and implementation. Business continuity and disaster recovery planning It's critical that companies understand the degree of potential damage and revenue losses that different types of business interruptions can cause. The main goals of a business continuity plan are to improve responsiveness by the employees in different situations, ease confusion by providing written procedures and participation in drills and help ensure logical decisions are made during a crisis. The necessary software -- the operating systems, programs and utilities used during regular business -- must also be backed up regularly to the offsite facility.
Emergency response Finally, emergency response drills are necessary not only to minimize asset damage and preserve life, but to reduce the chance of fraud, theft and vandalism since the security mechanisms usually in place may be completely disabled. Business Continuity Planning Process Diagram - Text VersionWhen business is disrupted, it can cost money.
Today, approximately 65% of companies could not stay in business if they had to be closed for a week or longer. Business continuity deals with keeping a company and business after a disaster has been experienced and takes a lot more into account than just technology. Almost every type of business interruption causes some direct or indirect affect on the productivity of a company, thus its revenue stream. The business continuity committee must identify the necessary skill set for each critical task and come up with back up solutions as in using temp agencies or cross training individuals.


More and more companies are developing business continuity into their environment because of the raised awareness of tragic possibilities, but also because of new regulatory requirements that infer executive management obligations for fiscal responsibility. The business case can include current vulnerabilities, regulatory and legal obligations, current status of recovery plans and recommendations. You would need to replace all computer resources, networking -- maybe even people -- as well as find a new site to get your business running again. Companies unable to support the ongoing service fees required for these options sometimes make arrangements with compatible companies who will host each other's employees and business functions in the event of a disaster. The decision of how a company should plan to recover is purely a business decision and should be treated as such. This is by far the least expensive, but is also the most risky since few companies maintain the extra capacity and equipment that would be suitable to host another company's business processes. Therefore, recovery strategies for information technology should be developed so technology can be restored in time to meet the needs of the business. The worksheet should be completed by business function and process managers with sufficient knowledge of the business.
Once all worksheets are completed, the worksheets can be tabulated to summarize:the operational and financial impacts resulting from the loss of individual business functions and processthe point in time when loss of a function or process would result in the identified business impactsThose functions or processes with the highest potential operational and financial impacts become priorities for restoration. The Business Continuity Resource Requirements worksheet should be completed by business function and process managers. Completed worksheets are used to determine the resource requirements for recovery strategies.Following an incident that disrupts business operations, resources will be needed to carry out recovery strategies and to restore normal business operations.


Meetings with individual managers should be held to clarify information and obtain missing information.After all worksheets have been completed and validated, the priorities for restoration of business processes should be identified. This information will be used to develop recovery strategies.Recovery StrategiesIf a facility is damaged, production machinery breaks down, a supplier fails to deliver or information technology is disrupted, business is impacted and the financial losses can begin to grow.
Recovery strategies are alternate means to restore business operations to a minimum acceptable level following a business disruption and are prioritized by the recovery time objectives (RTO) developed during the business impact analysis.Recovery strategies require resources including people, facilities, equipment, materials and information technology.
Staff with in-depth knowledge of business functions and processes are in the best position to determine what will work. This strategy requires ensuring telecommuters have a suitable home work environment and are equipped with or have access to a computer with required applications and data, peripherals, and a secure broadband connection.In an emergency, space at another facility can be put to use. Equipping converted space with furnishings, equipment, power, connectivity and other resources would be required to meet the needs of workers.Partnership or reciprocal agreements can be arranged with other businesses or organizations that can support each other in the event of a disaster.
Periodic review of the agreement is needed to determine if there is a change in the ability of each party to support the other.There are many vendors that support business continuity and information technology recovery strategies.
External suppliers can provide a full business environment including office space and live data centers ready to be occupied.
