What is Cyber Resilience?
Having a well-defined approach to managing a wide range of cyber risks is crucial for organisations cyber resilience, regardless of their size.
The objective of any cyber resilience strategy is to effectively prepare for, respond to, and swiftly recover from cyber risks, enabling businesses to maintain their operations with minimal disruption to workflow and processes. A solid cyber resilience plan is established based on a comprehensive assessment of the most probable cyber risks that your business may encounter, these risks encompass both internal threats arising from individuals within the organisation and external risks such as data breaches and ransomware attacks.
The persistence of cybercriminals knows no bounds. Leveraging automation, they possess the capability to target any organisation with a digital presence. The stark reality is that every business, irrespective of its industry, is susceptible to a cyberattack. In fact, a staggering 32% of businesses in the UK alone reported experiencing an attack within the past year. Relying solely on prevention measures is no longer sufficient for an effective cyber security strategy. It is imperative to prepare your business for the inevitable and equip it with the ability to withstand and recover from incidents like cyberattacks or data breaches.
Enter cyber resilience—an approach that combines information technology security, business continuity, and organisational resilience. Your cyber security strategy should extend beyond merely pondering how to avoid such events and delve deep into the specifics of how your business will respond if an attack occurs.
Why is cyber resilience important?
A cyber resilience strategy plays a crucial role in ensuring business continuity. It not only enhances an enterprise’s security posture and reduces the risk of critical infrastructure exposure, but also brings several other significant benefits. By prioritizing cyber resilience, businesses can mitigate financial risks, build trust with their customers, and gain a competitive advantage by delivering effective and efficient operations. It is a holistic approach that safeguards not only the organization’s security but also its overall resilience and long-term success.
What are the objectives of cyber resilience?
- Maintaining an appropriate state of cybersecurity preparedness to prevent or minimize compromises to business functions. This involves continuous security monitoring to identify and address attacks that cannot be blocked.
- Enabling the organisation to maintain essential business functions during a disruptive cyber incident.
- Facilitating the restoration of critical business functions following a breach.
- Leveraging the insights gained from attacks to help the organisation adapt its business functions and cyber capabilities, thereby enhancing its overall cyber resilience.
What are the various elements of a robust cyber resilience strategy?
Leveraging proactive and reactive defence measures
Leveraging proactive and reactive defence, like the adoption of a Security Operations Centre, is a vital component of a cyber resilience strategy. It involves dedicated cybersecurity teams working in conjunction with tools and policies to safeguard an organisation’s IT ecosystem, including networks, hardware, and data. Through continuous monitoring, detection, defence, and response, cyber defence helps protect against malicious attacks and unauthorised intrusions. In addition, cybersecurity policies and solutions play a crucial role in ensuring the security of remote workers.
Adopting the appropriate risk management policies
Risk management focuses on identifying potential risks that can impact an organisation’s IT ecosystem. These risks encompass various threats, such as hacking, data breaches, IT espionage, human error, hardware failures, natural disasters, and power outages. By thoroughly assessing and managing these risks through specific information security policies and processes, organisations can enhance their cyber resilience.
Adopting a business continuity plan
Business continuity refers to an organisation’s ability to maintain operational viability and provide uninterrupted services in the face of short-term disruptions. Cyber resilience plays a crucial role in supporting business continuity efforts, the widespread disruption caused by Covid-19 pandemic highlighted the importance of business continuity planning. Organisations are now revisiting and enhancing their existing plans to address limitations and develop more comprehensive business resilience strategies.
Implementing endpoint protection tools:
With a growing number of attacks targeting workforces, utilising an endpoint protection (EPP) tool as part of your cyber resilience strategy is crucial. EPP tools proactively block attacks and help contain breaches if they occur. These solutions have advanced significantly from basic antivirus software and now include features such as content control, USB blocking and device isolation.
Utilising network security tools:
From firewalls to intrusion detection and prevention systems, network security should already be part of your existing security investments. These tools safeguard your organisation’s network and provide high-fidelity data, enabling identification of attack indicators that may not be available from other log sources. When properly configured, these tools can be the first to alert you to malicious activity.
Employing a Security Information and Event Management (SIEM) system:
SIEM is a software solution that consolidates and correlates security log data from various sources to generate actionable alerts. Implementing a SIEM platform helps your organisation monitor its environment for suspicious activity and understand the necessary steps to remediate any issues.
Implementing identity and access management controls:
By controlling access to resources and information within your organisation, identity and access management ensures that only authorised personnel can access sensitive data. This significantly reduces the impact of a cyber incident by limiting the data that potential attackers can access and exfiltrate.
Adopting security awareness training
Designed to educate employees about cyber threats and how to protect themselves and the organisation, security awareness training is crucial. When executed effectively, this training is engaging and has a tangible impact on frontline security. However, it is essential to ensure that security is genuinely embedded in your workforce culture to avoid complacency and unnecessary risks.
What are the Benefits of a Cyber Resilience strategy?
- Reduce Financial Impact and losses: Resilient organisations prioritise proactive planning and preparation over reactive real-time responses. By having comprehensive contingencies in place, they effectively prevent service disruptions and mitigate business losses during events. Resiliency measures help avoid enduring costs such as civil penalties and legal proceedings in the long run.
- Reduce downtime, quicker recovery time: A comprehensive cyber resilience strategy will ensure the continuous functionality of your organisation before, during and after a cyber attack.
- Improve System Security: Cyber resilient organisations with stronger, agile cybersecurity approaches are better equipped to minimise the impacts of security breaches. They implement geographically distributed systems, secure backups, and other measures that facilitate faster responses and expedited recoveries.
- Better Legal and Regulatory Compliance: Non-compliance with global data regulations can result in fines, penalties, and legal actions. Implementing an effective cyber resilience framework enables organisations to assess their security posture, identify vulnerabilities that may lead to non-compliance, and address those gaps to meet legal and regulatory requirements.
- Reduce Burdens on Security and IT teams: Cyber resilient organisations embrace technologies that provide continuous monitoring of systems, detecting both threats and compliance issues. Instead of overwhelming SOC teams with a flood of alerts, these systems can automatically handle low-level issues, allowing security personnel to focus on critical incidents that require immediate attention.
- Better Security Culture and Internal Process: Human error poses a significant cybersecurity risk. Cultivating a culture of cyber resilience clarifies individual responsibilities within the framework of business continuity, leading to enhanced employee security compliance and a stronger security posture overall.
- Protect Brand Reputation and improve customer confidence: Experiencing a data breach incident can have consequences that extend beyond financial losses for your business. It can damage your brand’s reputation and erode customer trust.
- Gain a competitive advantage: By emphasizing resilience, organisations can gain a competitive edge and attract customers who prioritize stability and continuity in their partnerships.
How to create a cyber resilience strategy
To build a robust cyber resilience strategy, you must focus on these key aspects:
