Alternate Recovery Sites
An alternate recovery site is a separate location used for business operations when these cannot be carried out at the primary site (normal operating location) after a disaster has occurred.
In the aftermath of an incident, the primary site may not be available for business operations. To address such scenarios, organizations should have arrangements for the resumption of services from an alternate site to ensure the continuity of business operations. Many organizations cannot afford the discontinuity of business processes even for a single day, so they need to invest heavily in an alternate recovery site. These arrangements vary according to the needs of the business.
From the CISA exam perspective, candidates should have an understanding of the alternate recovery sites shown in Figure 8.4 and discussed in detail in the next subsections.
