Business Continuity Planning and Disaster Recovery Planning
Business Continuity Planning (BCP) is the process of creating systems and procedures to ensure the continuation of critical business functions during and after a crisis or disruptive events. BCP focuses on preserving an organization's assets, reputation, and ability to operate. Disaster Recovery Planning (DRP) is a subset of BCP, focusing specifically on restoring essential IT resources and data after an outage or catastrophe. Both BCP and DRP involve risk assessment, impact analysis, establishment of recovery objectives, and the creation of policies, plans, and procedures to guide organizations during emergencies and ensure timely restoration of operations.
Guide: Business Continuity Planning and Disaster Recovery Planning
Business Continuity Planning (BCP) and Disaster Recovery Planning (DRP) are important because they prepare businesses for unexpected events that could disrupt operations, such as natural disasters, cyber attacks, or other emergencies.
BCP aims at ensuring continuous business operations. It involves identifying potential threats and planning responses to mitigate their impact.
DRP, a subset of BCP, focuses on restoring the IT infrastructure and systems back to normal after a disaster.
The process for both is typically:
1. Analysis: Understanding potential threats and their impact.
2. Strategy: Deciding on how to approach the problem, including resource allocation.
3. Implementation: Developing the plan and implementing safeguards.
4. Testing: Regularly testing the plan to ensure it works.
5. Maintenance: Updating the plan as necessary following testing or as the business changes.
Exam Tips:
Questions on BCP and DRP typically test your understanding of main concepts and processes rather than technical details, so focus on the 'why' and 'how' more than the 'what'. Don't be afraid to make educated guesses if unsure. Look for answers that highlight prevention, response and recovery. Remember, BCP is broader and encompasses DRP. And finally, real-life scenarios are a common question-type so put yourself in the shoes of the person dealing with the incident.
