In the world of cybersecurity, the Certified Information Security Manager (CISM) certification is highly regarded. A key component of CISM is understanding how organizations can prepare for and respond to disruptions through Business Continuity and Disaster Recovery plans.
What is Business Continuity?
Business Continuity (BC) involves creating systems of prevention and recovery to ensure that an organization can continue to operate during and after a disruptive event. It focuses on maintaining essential functions and minimizing downtime.
What is Disaster Recovery?
Disaster Recovery (DR) is a subset of Business Continuity that specifically deals with restoring IT systems and data after a disaster. It involves planning how to recover hardware, applications, and data to resume normal operations.
