Business Continuity, Disaster Recovery, and Incident Response

Study ISC2 CC business continuity, disaster recovery, and incident response concepts for entry-level cybersecurity roles.

This domain is only 10% of the current CC outline, but it creates many scenario traps. The exam expects you to preserve sequence: plan before crisis, detect before contain, contain before recover, and improve after restoration.

Work this domain in order

  1. Business Continuity and Disaster Recovery for BIA, BCP, DRP, RTO, RPO, backups, and recovery validation.
  2. Incident Response for preparation, detection, analysis, containment, eradication, recovery, communication, and lessons learned.

The key distinction

Concept Primary question
Business continuity How do essential business functions continue during disruption?
Disaster recovery How do IT systems and data return to operation?
Incident response How does the organization handle a suspected or confirmed security event?

Exam sequence rule

	  P["Prepare"] --> D["Detect and analyze"]
	  D --> C["Contain"]
	  C --> E["Eradicate"]
	  E --> R["Recover"]
	  R --> L["Lessons learned"]

Wrong answers often skip directly to recovery or deletion before preserving evidence and limiting damage.
