Availability — CISSP Practice Questions
Availability is the security property that ensures authorized users can access information and systems when needed. The CISSP exam addresses availability through topics such as fault tolerance, redundancy, disaster recovery, business continuity planning, and denial-of-service attack mitigation. Candidates must understand availability metrics such as RTO, RPO, MTTR, and MTTF, and know how to apply them in recovery planning scenarios. Availability is often in tension with security hardening measures, and exam questions may test the candidate's ability to balance these competing priorities in a business context.
