What is Cyber Resilience?
The digital age has brought countless benefits, from connecting people around the world to streamlining business operations. However, it has also introduced a myriad of cyber threats that can jeopardize data security and business continuity. This is where the concept of cyber resilience comes into play – a proactive approach that not only protects organizations but also enables them to thrive in the face of adversity.
In this blog post, we will explore cyber resilience, its importance, and how organizations can develop and implement effective strategies to address the ever-evolving cyber landscape.
Cyber resilience refers to an organization’s ability to withstand, recover from, and adapt to cyber threats and incidents.
It involves proactive planning, incident response, business continuity measures, and learning from past breaches.
Cyber resilience aims to ensure the organization’s survival and maintain service provision despite cyber attacks or failures.
Defining Cyber Resilience
Cyber resilience is the capability of an organization to anticipate, withstand, and recover from cyber threats, ultimately ensuring the success of the organization despite any difficult situations. The National Institute of Standards and Technology (NIST) defines cyber resilience as the ability to prepare for, withstand, bounce back from, and adjust to adverse conditions, stresses, attacks, or breaches on systems enabled by cyber resources. It is a vital part of the information system security policies and procedures. In other words, cyber resilience aims to safeguard organizations by enabling them to maintain their core business operations during disasters, attacks, or other disruptive forces.
Achieving cyber resilience involves a holistic approach, encompassing various aspects such as identity and access management, data security, and the use of artificial intelligence and machine learning to recognize patterns of behavior and risk, and automate the response. Digital transformation also plays a crucial role in building enterprise resilience, as companies with strong digital capabilities can swiftly adapt and overcome challenges like supply chain disruptions and customer demands.
The Evolution of Cyber Resilience
Cyber resilience became one of the main topics discussed on a national level in the United States in 2013. This was prompted by the issuance of the Presidential Policy Directive (PPD-21) on Critical Infrastructure Security and Resilience that same year. This directive aimed to strengthen the security and resilience of critical infrastructures such as nuclear reactors, wastewater systems, and dams. Since then, it has become increasingly apparent that traditional security controls like penetration testing and security questionnaires are insufficient to minimize cyber risk, making cyber resilience and attack surface management essential.
As the world becomes more interconnected and dependent on technology, the importance of cyber resilience continues to grow. From critical sectors like electricity, water, and transportation to everyday businesses, the need for a robust and adaptive approach to cybersecurity and cyber resilience has never been more crucial. With a constantly evolving threat landscape, organizations must be agile and innovative in their approach to protecting their assets and ensuring business continuity.
The Significance of Cyber Resilience
Certain critical sectors, such as electricity, water, transportation, communications, and financial services, face heightened risks due to their interdependency and the potentially swift and far-reaching consequences of a cyberattack on their cyber-physical assets. To address these challenges, organizations must develop a comprehensive understanding of their security posture, including their IT assets, infrastructure, and the effectiveness of their security controls. Adverse cyber events can have serious implications for an organization. They can seriously compromise confidentiality, integrity, and availability. That’s why it is important to take the necessary precautions.
As Lt. Gen. Ted F. Bowlds aptly stated, “You’re gonna get hit, your computers are gonna get hit. The real question is, how do you keep going despite the attack?” This sentiment underscores the significance of cyber resilience – the ability to not only defend against cyber threats but also recover and adapt in the face of adversity, ensuring the ongoing success and stability of the organization.
Core Principles of Cyber Resilience
NIST outlines four strategic principles for achieving cyber resilience: anticipate, withstand, recover, and adapt. These principles provide a systematic, structured, and adaptive approach to cyber resilience, requiring organizations to develop a strategy tailored to their needs and objectives. This includes identifying and prioritizing risks, implementing cyber resilience techniques, and addressing cyber resilience challenges.
It is important to recognize that cyber resilience is not solely the responsibility of the CIO or Chief Information Security Officer. Instead, it is a business-wide responsibility that requires collaboration and commitment from all members of the organization to be prepared to respond to and recover from cyber incidents.
Assessing and Enhancing Cyber Resilience
Organizations can evaluate their cyber resilience using tools such as the Cyber Security & Infrastructure Security Agency’s (CISA) Cyber Resilience Review (CRR) and NIST’s SP 800-160 Vol. 2 framework. The CRR, for instance, is an assessment tool designed to help organizations identify critical services, staff training, and other aspects of preparing for adverse events. By utilizing these frameworks, organizations can gain valuable insights into their current security posture and identify areas for improvement.
Boosting cyber resilience requires continuous visibility across the environment, identifying all IT assets connected to the organization, understanding which IT assets are at risk, having business context about these assets, and utilizing cyber risk dashboards to provide visibility into an organization’s risks in monetary terms. Additionally, detecting threats and implementing effective security controls are essential components of a robust cyber resilience strategy.
Identifying and Prioritizing Risks
To effectively plan for adverse events, organizations must consider key elements such as risk assessment, incident response planning, security awareness training, and data backup and recovery. By evaluating the potential impact, likelihood, and cost of each risk, as well as the resources available and the potential return on investment of each action, organizations can prioritize their mitigation actions and allocate resources accordingly.
Identifying and prioritizing risks not only helps organizations effectively allocate resources, but it also ensures that the most critical assets and sensitive data receive the appropriate level of protection. This enables organizations to maintain business resilience and ensure business continuity in the face of potential cyber threats.
Implementing Cyber Resilience Techniques
The NIST report outlines 14 cyber resilience techniques, including analytic monitoring, privilege restriction, redundancy, and deception, among others. These techniques can help organizations effectively respond to and recover from cyber threats, while also proactively protecting their IT infrastructure and data.
Implementing these cyber resilience techniques involves a combination of technologies, processes, and people, along with a deep understanding of the threat landscape and the organization’s IT infrastructure. By adopting a comprehensive approach that leverages these techniques, organizations can strengthen their cyber resilience and better protect themselves from the ever-evolving landscape of cyber threats.
Overcoming Cyber Resilience Challenges
Some of the key challenges organizations will face in achieving cyber resilience in 2023 include adapting to evolving threats, reducing the attack surface, and building resilience in the face of economic instability and geopolitical conflicts. To address these challenges, organizations must invest in talent development and leverage innovative tools and technologies, such as the CyberForce program, which helps bridge the gap in cybersecurity expertise by involving college students and recent graduates in cyber competitions and career events.
By fostering a culture of continuous learning and improvement, organizations can better equip themselves to tackle the changing cyber threat landscape and ensure their cyber resilience. This involves cultivating a workforce with the necessary skills and knowledge to address emerging threats, as well as leveraging advanced security tools and automation to stay ahead of potential risks.
