Recovery Strategies

5 minutes 5 Questions

Recovery Strategies refer to the measures and actions that an organization implements to restore critical business functions and processes after a disruptive event. These strategies are formulated based on the outcome of the Business Impact Analysis and tailored according to the specific risks faced by the organization. Examples of recovery strategies include data backup and restoration, alternate processing sites, work area recovery, employee cross-training, and supply chain redundancy. The ultimate goal of recovery strategies is to minimize downtime and ensure the timely resumption of business operations.

Guide to Recovery Strategies In Business Continuity Planning (CISSP)

Importance:
The importance of recovery strategies in business continuity planning cannot be overstated. They are essential in ensuring that businesses can quickly bounce back after an unforeseen disruption or catastrophe. The failure to have a well-defined recovery strategy can lead to significant financial losses, harm to the organization’s reputation, and potentially, the failure of the business.

What It Is:
Recovery strategies are backup plans that an organization implements to restore its critical business operations during a disruption or disaster. These strategies include preventive measures to avoid disasters, detection measures to identify points of interruption, and corrective measures to recover the disrupted functions.

How It Works:
Recovery strategies work by identifying critical business functions and elements which are crucial for the organization's operation. Following this, detailed plans and procedures are developed to ensure the recovery of these critical functions within a stipulated time, post any disruptive event or disaster. The key components include recovery point objective (RPO), recovery time objective (RTO), and maximum tolerable downtime (MTD).

Exam Tips: Answering Questions on Recovery Strategies:
Preparation is key when tackling questions on recovery strategies. Firstly, understand the components thoroughly. For example, understand the difference between RTO, RPO, and MTD. Additionally, be aware of the possible types of recovery strategies, such as cold sites, warm sites, and hot sites. Remember that you may have to select the most appropriate recovery strategy for a given scenario in the exam. Pay attention to the hints in the scenario, such as urgency, sensitivity of data, and available resources. Finally, practice as much as possible. This isn't a topic you can cram - it's all about understanding the principles and applying them to a variety of scenarios.

Question 1

A security manager is reviewing the disaster recovery plan for an organization. They want to ensure maximum protection of data confidentiality while still ensuring a reliable recovery process. What should be included in the recovery plan?

On-site backups only with encryption at rest Storing data backups in employees' homes Off-site backups with encryption at rest Off-site backups without encryption

Correct Answer: Off-site backups with encryption at rest

The correct answer is to include off-site backups with encryption at rest. This provides maximum confidentiality through encryption and reliability through off-site storage. Other answers do not sufficiently protect confidentiality or could hinder efficient recovery in case of disaster.

Question 2

A company has noticed that some employees take an extended period to recover their work information after a temporary system failure occurs. Management would like suggestions to improve this situation. Which strategy would you recommend?

Require manual backup by each employee every day Implement a virtual desktop infrastructure (VDI) solution Increase employee training on system recovery Provide employees with additional external hard drives

Correct Answer: Implement a virtual desktop infrastructure (VDI) solution

Implementing a virtual desktop infrastructure (VDI) solution is the most effective strategy to address the issue of employees taking an extended period to recover their work information after a temporary system failure. VDI centralizes desktop environments on remote servers, allowing users to access their desktops and applications from any device. This approach ensures that employee data and work environments are stored centrally, making recovery after a system failure much quicker and more efficient. VDI eliminates the need for individual backups or manual processes, provides consistent access to work information, and reduces downtime. It also offers better security and easier management for IT teams, making it an ideal solution for improving overall system resilience and minimizing recovery time after temporary failures.

Question 3

A natural disaster has caused significant damage to your company's data center. To ensure business continuity, management wants your recommendations on which recovery strategy to pursue. Which of the following options would you suggest?

Relocate the on-site data center to a different floor of the building Implement a hot site for critical business systems Purchase more servers to keep on-site as a backup Take backups of all data, but do not store them off-site

Correct Answer: Implement a hot site for critical business systems

The correct answer is to implement a hot site for critical business systems. This ensures minimal downtime and highest availability in case of disasters. Other options might not prevent downtime, and some could lead to increased vulnerabilities.
