Incident Response Plan

Timing and Sequence of CP Elements

As indicated earlier, the IR plan focuses on immediate response, but if the incident escalates into a disaster, the IR plan may give way to the DR plan and BC plan, as illustrated in Figure 10-9. The DR plan typically focuses on restoring systems after disasters occur and is therefore closely associated with the BC plan. The BC plan occurs concurrently with the DR plan when the damage is major or long term, requiring more than simple restoration of information and information resources, as illustrated in Figure 10-10.

Some experts argue that the three planning components (IR, DR, and BC) of CP are so closely linked that they are indistinguishable. Actually, each has a distinct place, role, and planning requirement. Furthermore, each component comes into play at a specific time in the life of an incident. Figure 10-11 illustrates this sequence and shows the overlap that may occur. How the plans interact and the ways in which they are brought into action are discussed in the following sections.
