Why Cyber Resilience is not Cyber Security

In today’s digital landscape, protecting sensitive information and safeguarding against cyber threats has become a top priority for organisations. Two concepts that often come up in this context are cyber resilience and cyber security. While related, there are distinct differences between the two disciplines and also to business continuity planning. This post outlines the intricacies of cyber resilience and cyber security, their roles, key components, challenges, and how they compare to each other. Furthermore, we will explore factors to consider when deciding how to implement the two and provide insights into future trends in this ever-evolving field.

Understanding Cyber Security

Before we explore the realm of cyber resilience, it is crucial to have a comprehensive understanding of cyber security. Cyber security encompasses policies, processes, and technologies designed to protect digital systems, networks, and data from unauthorised access, attacks, and damage. Its primary goal is to mitigate risks and prevent hackers from compromising sensitive information. Cyber security is a constantly evolving field that requires organisations to stay vigilant and adapt to emerging threats. With the increasing reliance on technology and the growing interconnectedness of digital systems, the importance of cyber security cannot be overstated.

One of the key roles of cyber security is to establish a robust defence system to identify and thwart potential threats. This includes implementing firewalls, intrusion detection systems, and encryption protocols. By deploying these security measures, organisations create multiple layers of protection to safeguard their digital assets.

Additionally, cyber security teams play a vital role in monitoring networks for unusual activity, investigating security incidents, and developing incident response plans. They’re responsible for analysing security logs, conducting vulnerability assessments and implementing security patches to ensure the ongoing integrity of digital systems.

The Role of Cyber Security

The role of cyber security extends beyond protecting digital systems from external threats. It also involves educating employees about best practices for online safety and promoting a culture of security awareness within organisations. By fostering a security-conscious environment, organisations can empower their employees to be the first line of defence against cyber attacks.

Furthermore, cyber security professionals are instrumental in conducting risk assessments and developing risk management strategies, or particular importance is the need to assess the potential impact of cyber threats on business operations and work closely with stakeholders to implement appropriate security controls. A good place to start is with an ISMS.

Key Components of Cyber Security

Cyber security has many components, each playing a crucial role in protecting digital assets, including network security, application security, data security, and endpoint security.

Network security focuses on securing the network infrastructure and preventing unauthorised access. It involves implementing measures such as firewalls, virtual private networks (VPNs), and intrusion detection systems (IDS) to monitor and control network traffic.

Application security ensures that software applications are free from vulnerabilities that could be exploited by attackers. This involves conducting code reviews, implementing secure coding practices, and regularly updating and patching applications to address any identified vulnerabilities.

Data security involves measures to protect data from unauthorised access, alteration, or destruction. This includes implementing access controls, encryption techniques, and data backup strategies to ensure the confidentiality, integrity, and availability of sensitive information.

Endpoint security encompasses securing individual devices such as computers, laptops, and smartphones. It involves deploying antivirus software, implementing device encryption, and enforcing strong password policies to protect against malware, data theft, and unauthorised access.

Challenges in Cyber Security

While cyber security is essential for protecting against known threats, it faces many challenges. The rapidly evolving threat landscape, sophisticated attack techniques and shortage of skilled cybersecurity professionals make it increasingly difficult to stay ahead of potential threats.

Cybercriminals are constantly developing new methods to exploit vulnerabilities and bypass security measures. They employ tactics such as social engineering, phishing attacks and zero-day exploits to gain unauthorised access to systems and steal sensitive information.

Furthermore, the increasing complexity of IT systems and the growing number of connected devices creates vulnerabilities that can be exploited by cybercriminals. The Internet of Things (IoT) has introduced a multitude of new entry points for attackers, as interconnected devices often lack the required robust security measures.

Addressing these challenges requires organisations to adopt a proactive approach to cyber security. This includes investing in advanced threat detection and prevention technologies, conducting regular security assessments and providing ongoing training to employees to enhance their security awareness and response capabilities.

Cyber security is therefore a critical discipline that plays a vital role in protecting digital systems, networks, and data from unauthorised access and attacks. By understanding the various components of cyber security and the challenges it faces, organisations can better prepare themselves to mitigate risks and safeguard their digital assets.

Delving into Cyber Resilience

Unlike cyber security, which is primarily focused on prevention and defence, cyber resilience takes a holistic approach by emphasising the ability to withstand, recover and adapt to cyber threats. An important difference is that it also ensures business continuity, even in the face of cyber attacks and unforeseen disruptions. Whilst there is no specific Cyber Resilience Standard at the time of writing, the ISO22301standard is a good startpoint.

Cyber resilience is not about preventing cyber attacks; it’s about being prepared for them. It’s about having the ability to bounce back and continue operations even when faced with sophisticated and persistent threats. This concept goes beyond traditional cyber security measures and focuses on response, recovery and restoration of key services, functions and processes.

Organisations with a cyber resilient system can effectively manage cyber risks, minimise the impact of security incidents and quickly recover operations following an attack. By adopting a proactive and comprehensive approach, cyber resilience enables organisations to withstand and bounce back from unforeseen disruptions.

The Concept of Cyber Resilience

Cyber resilience is a multifaceted concept that encompasses various aspects of an organisation’s security posture. It involves not only preventing cyber attacks but also responding to them effectively and recovering from them efficiently. It’s about building a system that can withstand the ever-evolving threat landscape and adapt to new challenges.

One key aspect of cyber resilience is the ability to detect and respond to security incidents in real-time. This requires organisations to have robust Cyber Incident Response Plan (CIRP) in place, with clear roles and responsibilities defined. It also involves investing in advanced threat detection and monitoring tools to identify and mitigate potential threats before they cause significant damage.

Another important aspect of cyber resilience is the ability to recover operations quickly following an attack. This involves having regular backups of critical data and systems, as well as well-defined business continuity processes. By having these measures in place, organisations minimize downtime and resume normal operations as soon as possible.

Importance of Cyber Resilience

In today’s interconnected world, cyber attacks are not a matter of “if”, but “when.” Organisations of all sizes and industries are constantly targeted by cyber criminals seeking to exploit vulnerabilities and gain unauthorised access to sensitive information. In this landscape, cyber resilience is no longer a luxury; it’s a necessity.

Cyber resilience is essential for organisations to maintain their critical functions, protect their reputation, and ensure customer trust. By embracing cyber resilience, organisations minimize the impact of security breaches, reduce downtime, maintain customer confidence and swiftly resume normal operations. This adaptability and resilience are vital in an era where cyber threats are becoming increasingly sophisticated and persistent.

Furthermore, cyber resilience is not just about protecting internal systems and data; it also extends to the broader ecosystem, including third-parties. Organisations need to collaborate with their partners, suppliers and customers to ensure a resilient and secure supply chain. By working together, they can collectively enhance their cyber resilience and better defend against common threats.

Building a Cyber Resilient System

Building a cyber resilient system involves numerous considerations, encompassing people, processes, and technology. Organisations need to invest in the right tools and technologies to detect, prevent, and respond to cyber threats effectively.

Firstly, organisations should conduct thorough risk assessments to identify and prioritise potential vulnerabilities. This involves evaluating the organisation’s assets, systems, and processes to identify potential weaknesses and develop appropriate mitigation strategies. By understanding the risks they face, organisations can allocate resources effectively and implement targeted security measures.

One crucial aspect of building a cyber resilient system is implementing robust Cyber Incident Response and Business Continuity Plans. These plans should outline the steps to be taken in the event of a security incident, including the roles and responsibilities of key personnel. Regular drills and simulations can help ensure that everyone is familiar with the procedures and know how to respond effectively under pressure.

In addition plans, organisations need to prioritise regular backups of critical data and systems. This ensures that even if an attack occurs, the organisation can quickly recover its operations without significant data loss. Regular testing of backup ‘restores’ is essential to ensure their integrity and reliability.


Employee awareness and training are also critical components of building a cyber resilient culture. Employees are often the first line of defence against cyber threats and their actions can have a significant impact on an organisation’s security posture. Regular training sessions can help employees understand the latest threats and best practices for maintaining a secure and resilient environment. This also involves fostering a mindset where everyone understands their role in maintaining a secure environment and takes responsibility for their actions. It involves promoting open communication and collaboration, so that potential threats and vulnerabilities can be identified and addressed promptly.

In conclusion, cyber resilience is a vital aspect of modern-day security. By including business continuity concepts, it goes beyond traditional cyber security measures and focuses on the ability to withstand, recover and adapt to cyber security threats and incidents. By embracing cyber resilience, organisations minimize the impact of security incidents, reduce downtime, and ensure business continuity even in the face of cyber attacks and disruptions.
