The Importance of Resiliency Testing for Cyber and Disaster Preparedness

On July 19, 2024, the world watched as a faulty CrowdStrike update caused approximately 8.5 million Windows systems to crash, resulting in widespread disruptions. The incident has been described as the largest outage in IT history with an estimated financial impact of at least $10 billion.

This unprecedented event underscored the vulnerability of our interconnected digital infrastructure and highlighted the pressing need for robust resiliency testing protocols. As businesses and governments increasingly rely on complex, interdependent technological systems, the potential for cascading failures grows exponentially. The CrowdStrike incident demonstrated that even the most technologically sophisticated firms are not immune to errors that can have far-reaching consequences.

In this ever-changing landscape, traditional disaster recovery plans, while essential, are no longer sufficient on their own. True resilience demands a proactive approach that goes beyond static documentation and occasional drills. Organizations must embrace continual testing and refinement of their disaster preparedness strategies to ensure they can withstand real-world conditions and operational anomalies.

The Limitations of Traditional Disaster Recovery Plans

Traditional disaster recovery plans often fall short due to their static nature. These plans are typically updated infrequently, quickly becoming outdated in today’s rapidly evolving technological landscape, resulting in:

• Obsolescence: As systems, applications, and infrastructure change, static plans fail to reflect the current environment, rendering them ineffective when needed most.
• Lack of adaptability: Rigid plans struggle to accommodate any threats or scenarios that weren’t anticipated during their creation.
• Resource misallocation: Outdated plans may focus on protecting legacy systems while overlooking critical new assets, leading to an inefficient use of resources, or worse, a gap in protection.

Further complicating things, day-to-day operations often deviate from the idealized scenarios outlined in traditional disaster recovery plans. These operational anomalies can significantly hinder recovery efforts. Specific areas of concern include:

• Configuration drift: Over time, production environments may diverge from the documented state, causing recovery processes to fail or produce unexpected results.
• Undocumented dependencies: As systems evolve, new interdependencies may form that aren’t reflected in static plans, potentially causing cascading failures during recovery.
• Human factors: Staff turnover or role changes can leave plans referencing outdated contact information or assigning responsibilities to individuals no longer with the organization.

These limitations speak to the need for a more dynamic, adaptable approach to disaster preparedness — one that embraces continual testing and refinement to bridge the gap between theory and real-world execution.

The Role of Resiliency Testing

Resiliency testing is a proactive approach to disaster preparedness that involves regularly evaluating and refining an organization’s ability to withstand and recover from various disruptions. The primary objectives of resiliency testing are to:

• Identify vulnerabilities in existing disaster recovery and business continuity plans
• Validate the effectiveness of recovery processes and procedures
• Enhance the organization’s ability to respond to and recover from various threats
• Build confidence among stakeholders in the organization’s preparedness
• Ensure compliance with regulatory requirements and industry standards

There are numerous types of useful resiliency tests. For example, disaster simulations replicate scenarios like cyberattacks, natural disasters, or infrastructure failures. Business continuity exercises focus on testing the organization’s ability to maintain critical operations during and after a disruptive event. They rely on tabletop exercises, functional drills, and end-to-end testing of business continuity plans, often in conjunction with disaster simulations.

Backup and restore testing verifies data integrity and completeness, evaluates recovery time objectives (RTOs) and recovery point objectives (RPOs), and tests various recovery scenarios, including partial and full restores.

The Benefits of Continual Testing and Refinement

The key to resilience is to ensure that organizations can identify and address potential problems before they escalate into major incidents, thereby providing opportunities to fix issues during low-stress periods. Regular testing leads to enhanced recovery time and minimized downtime through streamlined procedures, faster identification and resolution of bottlenecks, and reduced impact during actual incidents.

Continual testing also builds operational confidence among staff and stakeholders, with team members becoming more familiar with their roles during crises, and leadership gaining assurance in the organization’s ability to handle disruptions. Successful testing also aids in meeting cyber insurance qualifications and regulatory compliance requirements, potentially leading to reduced premiums and improved coverage options.

Implementing a Resiliency Testing Program

A well-structured testing plan is key to resiliency and should include:

• Clear objectives
• Identification of critical systems
• Comprehensive testing schedules
• Delineation of roles and responsibilities

The plan should emphasize frequent testing, with comprehensive tests conducted at least quarterly and smaller-scale tests for critical systems more often than that. Comprehensive coverage of different components and scenarios can be ensured by using a rolling testing schedule, gradually increasing in complexity and including surprise elements.

Thorough documentation and post-test analysis are vital for continuous improvement. This involves developing standardized templates, recording detailed observations, conducting debriefing sessions, analyzing results to identify trends, updating plans based on findings, and sharing key insights with relevant stakeholders.

Overcoming Challenges in Resiliency Testing

Implementing comprehensive resiliency testing programs can be a challenge due to resource constraints, but can be mitigated through prioritization, automation, resource optimization, outsourcing, and a phased approach. Organizations should focus on critical systems, leverage automated tools, cross-train staff, partner with specialized firms, and start with manageable tests that can help them overcome these limitations.

Fostering a culture of continuous improvement is essential for long-term success in resiliency testing. This requires leadership participation, integrating resilience considerations into daily operations, encouraging open communication, providing ongoing education, setting clear goals, and continuously evolving the program.
