       Domain 7.0: Security Operations7.13 Participate in Business Continuity (BC) planning and exercises

      Resilient organizations have plans and procedures in place to help mitigate the effects a disaster has on their continuing operations and to speed the return to normal operations. Recognizing the importance of planning for business continuity (BC) and disaster recovery (DR), the International Information System Security Certification Consortium (ISC)2 included these two processes in the objectives for the CISSP program. Knowledge of these fundamental topics will help you prepare for the exam and help you prepare your organization for the unexpected.

      In this chapter, we'll explore the concepts behind business continuity planning (BCP). Chapter 18, “Disaster Recovery Planning,” will continue the discussion and delve into the specifics of the technical controls that organizations can put in place to restore operations as quickly as possible after disaster strikes.

      Business continuity planning (BCP) involves assessing the risks to organizational processes and creating policies, plans, and procedures to minimize the impact those risks might have on the organization if they were to occur. BCP is used to maintain the continuous operation of a business in the event of an emergency. The goal of BCP planners is to implement a combination of policies, procedures, and processes such that a potentially disruptive event has as little impact on the business as possible.

      BCP focuses on maintaining business operations with reduced or restricted infrastructure capabilities or resources. As long as the continuity of the organization's ability to perform its mission-critical work tasks is maintained, BCP can be used to manage and restore the environment.

      Business Continuity Planning vs. Disaster Recovery Planning

      CISSP candidates often become confused about the difference between business continuity planning (BCP) and disaster recovery planning (DRP). They might try to sequence them in a particular order or draw firm lines between the two activities. The reality of the situation is that these lines are blurry in real life and don't lend themselves to neat and clean categorization.

      In any event, don't get hung up on the difference between the two. We've yet to see an exam question force anyone to draw a solid line between the two activities. It's much more important that you understand the processes and technologies involved in these two related disciplines.

      You'll learn more about disaster recovery planning in Chapter 18.

      The overall goal of BCP is to provide a quick, calm, and efficient response in the event of an emergency and to enhance a company's ability to recover from a disruptive event promptly. The BCP process has four main steps:

       Project scope and planning

       Business impact analysis

       Continuity planning

       Approval and implementation

      The next four sections of this chapter cover each of these phases in detail. The last portion of this chapter will introduce some of the critical elements you should consider when compiling documentation of your organization's business continuity plan.

      none The top priority of BCP and DRP is always people. The primary concern is to get people out of harm's way; then you can address IT recovery and restoration issues.

      As with any formalized business process, the development of a resilient business continuity plan requires the use of a proven methodology. Organizations should approach the planning process with several goals in mind:

       Perform a structured review of the business's organization from a crisis planning point of view.

       Create a BCP team with the approval of senior management.

       Assess the resources available to participate in business continuity activities.

       Analyze the legal and regulatory landscape that governs an organization's response to a catastrophic event.

      The purpose of this phase is to ensure that the organization dedicates sufficient time and attention to both developing the project scope and plan and then documenting those activities for future reference.

      Organizational Review

      One of the first responsibilities of the individuals responsible for business continuity planning is to perform an analysis of the business organization to identify all departments and individuals who have a stake in the BCP process. Here are some areas to consider:

       Operational departments that are responsible for the core services the business provides to its clients

       Critical support services, such as the IT department, facilities and maintenance personnel, and other groups responsible for the upkeep of systems that support the operational departments

       Corporate security teams responsible for physical security, since they are many times the first responders to an incident and are also responsible for the physical safeguarding of the primary facility and alternate processing facility

       Senior executives and other key individuals essential for the ongoing viability of the organization

      This identification process is critical for two reasons. First, it provides the groundwork necessary to help identify potential members of the BCP team (see the next section). Second, it builds the foundation for the remainder
