Recovery Controls

5 minutes 5 Questions

Recovery controls are implemented to return an organization's systems and operations to normal after a security incident or disaster. They are focused on restoring the availability, integrity, and confidentiality of information and systems in the shortest time possible. Recovery controls can consist of business continuity planning, disaster recovery planning, backup and restoration, and redundant infrastructure. CISSP courses teach students how to develop strategies and plans that minimize downtime and ensure rapid recovery of systems and data after an incident occurs.

Guide on Recovery Controls

Importance:
Recovery Controls are crucial in any information security environment as they help to restore system functionality after a disruption or failure such as system crashes, power failures, or cyber-attacks. In addition, these controls minimize the potential impact of a disaster and maximize the effectiveness of security incident recovery.

What it is:
Recovery Controls are components of an organization's security policy designed to recover operations quickly and accurately during or after a security incident. Included in Recovery Controls are procedures for restoring systems, recovering data, performing normalization, and other important recovery actions.

How it works:
Recovery Controls follow a predefined incident response plan in the event of a disruptive incident. The process involves assessing the situation, implementing remedial measures, testing the effectiveness of the measures, and restoring operations back to normal. It might involve reconstructing data and systems, activating alternate solutions, or utilizing backup systems and data.

Exam Tips: Answering Questions on Recovery Controls:
During an exam:
- Understand the purpose and scope of Recovery Controls. Comprehend that Recovery Controls are designed to help organizations quickly recover from security incidents.
- Recognize the steps involved in the Recovery Control process such as situational assessment, restoration of systems, and normalization of operations.
- Be aware that choosing an appropriate Recovery Control depends on factors such as risk level, resource availability, and business impact.
- Know that Recovery Controls should be a part of the overall incident response plan and business continuity planning.
- Emphasize the role of recovery controls in minimizing business disruption, reducing recovery time, and returning systems and operations to their original or new normal condition.

Remember, in answering questions on Recovery Controls, knowledge and understanding of definitions, purpose, implementation, processes, and recovery strategies are vital.

Question 1

A cyber attack occurs while an organization is undergoing system maintenance. Many systems are offline, and backups are running. Which Recovery Time Objective (RTO) meets the situation's requirements?

Medium RTO Short RTO Long RTO Zero RTO

Correct Answer: Long RTO

A long RTO is appropriate when the organization can afford extended periods of downtime. In this scenario, ongoing maintenance and backup processes create a situation that doesn't require immediate recovery, meaning a long RTO would be suitable.

Question 2

In a data center, a fire broke out causing severe damage. The organization needs to restore its operations using a backup facility with minimum data loss. Which recovery control should be used?

Incremental backup Cold site Hot site Warm site

Correct Answer: Hot site

A hot site is a backup facility that is fully operational and has up-to-date data. It has a minimal switchover time and allows quick restoration with minimum data loss. Cold and warm sites require more time to set up. Incremental and differential backups are backup methods, not recovery controls. A mobile site is a portable recovery site but might not have the capacity to deal with a data center's operations.

Question 3

A company wants to implement a recovery control that stores data in a separate location from their primary site while maintaining direct control over their information. Which of the following options best meets their requirements?

Hot site Offsite storage Cold site Warm site

Correct Answer: Offsite storage

Offsite storage is the most appropriate recovery control for a company concerned about security implications of remote backup facilities while maintaining immediate control. It allows data to be stored in a separate location from the primary site, reducing the risk of data loss due to localized disasters or security breaches. Offsite storage provides a balance between security and accessibility, allowing the company to maintain control over their data while still benefiting from geographical separation. This option addresses the company's need for a separate location and immediate control better than the other alternatives, which primarily focus on the readiness level of disaster recovery sites rather than the specific storage of backup data.
