Cybersecurity has been making headlines across the UK, and there’s a lot to unpack. For CISOs in retail, healthcare, and manufacturing, these developments aren’t just news stories—they’re valuable lessons in how organisations can strengthen their defences. From a breach at DP World UK to regulatory scrutiny at Sellafield, and even cybercriminals using Microsoft Teams to impersonate IT staff, the evolving threat landscape reinforces the need for proactive security strategies.
Rather than focusing on the risks alone, let’s break down what these incidents mean, what can be learned from them, and how businesses can adapt to stay ahead.
What Can We Learn from Recent Incidents?
Take the DP World UK breach, for example. The company, a major logistics and supply chain operator, faced a cyber-attack in 2024 that disrupted operations and highlighted the vulnerabilities within critical infrastructure. While the organisation acted quickly to contain the incident, it highlights the importance of having robust incident response plans in place. For organisations in logistics, manufacturing, and beyond, this is a reminder that security isn’t just about prevention - it’s also about resilience. Ensuring that detection, containment, and recovery processes are well-rehearsed can make all the difference in minimising disruption.
Then there’s Sellafield, where regulatory action was taken due to long-term cybersecurity lapses. While nuclear sites have specific security challenges, the broader takeaway here is that cybersecurity hygiene is an ongoing process, not a one-off compliance exercise. Regular audits, visibility into assets, and continuous improvements to security controls are key to avoiding similar pitfalls in any industry.
Meanwhile, cybercriminals have found yet another way to exploit human behaviour - this time by impersonating IT staff on Microsoft Teams. This reinforces the need for security awareness training that goes beyond generic advice. Employees need to understand how these attacks work in real-world scenarios so they can spot red flags. Multi-factor authentication (MFA) and robust identity verification processes also play a crucial role in stopping attackers before they gain access.
The Importance of Basic Security Hygiene
While advanced security controls like MFA, endpoint detection, and zero-trust models are important, they are not a silver bullet. Cybercriminals continue to exploit weak passwords, unpatched systems, and lack of employee training. Simple yet effective security hygiene practices can significantly reduce an organisation’s risk. These include:
- Maintain a Comprehensive Asset Register: Catalogue all IT assets, including hardware, software, cloud services, third-party tools, and IoT devices. Regularly update the register and use automated discovery tools to detect and track assets in real time. Classify critical assets based on sensitivity and business importance.
- Implement a Robust Joiners, Leavers, and Movers (JLM) Process: Ensure new employees and contractors are granted access based on the principle of least privilege, with MFA enforced from day one. Revoke access immediately when employees leave and review permissions when roles change. Conduct periodic access reviews to remove unnecessary privileges.
- Enforce Strong Authentication: Implement MFA for all critical accounts, encourage passphrase use, and integrate Single Sign-On (SSO) with least privilege access to reduce password fatigue.
- Keep Systems and Software Updated: Apply patches and updates promptly. Automate updates for operating systems, third-party applications, and firmware. Conduct regular vulnerability scanning to identify and address security gaps.
- Enforce the Principle of Least Privilege (PoLP): Restrict administrative privileges to essential personnel only. Use role-based access control (RBAC) and regularly review permissions.
- Secure Endpoint Devices: Deploy up-to-date endpoint protection (e.g., antivirus, EDR). Enable disk encryption and enforce automatic screen locking after inactivity.
- Protect Against Phishing & Social Engineering: Conduct phishing simulations, educate employees on recognising and reporting phishing attempts, and implement email filtering solutions to block malicious emails.
- Secure the Network: Use firewalls, IDS/IPS, and network segmentation. Require encrypted connections (VPN, TLS, SSH) for remote access and enforce least privilege access to internal network resources.
- Implement a Strong Backup Strategy: Regularly back up critical data, maintain at least one offline copy, and test backup restoration procedures periodically. Use immutable backups to prevent ransomware attacks.
- Monitor & Detect Threats Early: Deploy Security Information and Event Management (SIEM) tools, implement Endpoint Detection and Response (EDR), and consider establishing a Security Operations Centre (SOC).
- Enhance Email & Web Security Controls: Implement DMARC, SPF, and DKIM to prevent email spoofing. Restrict employees from accessing untrusted websites and block execution of macro-enabled email attachments.
- Regular Security Awareness Training: Provide ongoing cybersecurity training, teach data handling best practices, and conduct tabletop exercises to improve incident response readiness.
- Secure Cloud Services: Implement access controls and monitoring for cloud platforms. Restrict public sharing of sensitive files and audit cloud permissions regularly.
- Apply Zero Trust Principles: Adopt an "assume breach" mentality, continuously verify access requests, require endpoint health checks, and restrict internal device communications.
- Develop a Robust Incident Response Plan: Document and test a comprehensive incident response plan, conduct regular exercises, and establish clear escalation and communication protocols.
- Review & Audit Security Practices Regularly: Perform security audits, penetration tests, and compliance assessments against industry frameworks (e.g., ISO 27001, NIST, CIS). Continuously refine security policies and procedures.
Basic cyber hygiene is the foundation of a strong security posture. When combined with advanced security tools, it creates a multi-layered defence that is harder for attackers to bypass.
The Impact on Retail, Healthcare, and Manufacturing
For the retail sector, cybersecurity is becoming a board-level priority. With a significant portion of sales happening online, securing e-commerce platforms, point-of-sale systems, and customer data is essential - not just to avoid breaches but to maintain trust. Investing in endpoint security and closely monitoring third-party vendors can help reduce risk.
In healthcare, cybersecurity directly impacts patient care. Ransomware attacks targeting hospitals have shown how critical it is to secure both IT networks and medical devices. As healthcare becomes more digital, zero-trust security models and real-time threat monitoring are becoming indispensable.
Manufacturing is also seeing an increase in targeted attacks, especially as production lines become more connected. Operational Technology (OT) and IT networks need to be properly segmented to prevent cyber threats from moving laterally within an organisation. Secure access controls and real-time anomaly detection can help manufacturers protect their supply chains and keep operations running smoothly.
Bridging the Cybersecurity Skills Gap
One of the biggest challenges for CISOs right now is finding the right talent to manage these threats effectively. The UK’s cybersecurity skills gap means organisations need to rethink how they build and retain security teams. Over the past few years, the UK's cybersecurity sector has faced notable challenges in addressing skills shortages:
- Prevalence of Skills Gaps: In 2024, approximately 30% of cyber firms reported technical skills gaps, a decrease from 49% in 2023. However, specific areas like incident management saw an increase in skills gaps, rising from 27% in 2020 to 48% in 2024. GOV.UK
- Workforce Dynamics: The UK's cybersecurity workforce grew to 367,300 in 2023 but experienced a 4.9% decline to 349,360 in 2024. Home | ISC2
- Basic Technical Skills: Around 44% of UK businesses reported gaps in basic technical cybersecurity skills in 2024. GOV.UK
These statistics highlight the ongoing need for organisations to invest in upskilling internal staff, leveraging automation where appropriate, and collaborating with external security providers to bridge the gap. Continuous training ensures that security teams stay ahead of emerging threats.

The Regulatory Landscape Is Changing
The UK government’s upcoming Cyber Security and Resilience Bill signals a shift towards greater accountability. It is proactively enhancing its cybersecurity regulations to strengthen national resilience:
- Cyber Security and Resilience Bill: Announced in July 2024, this forthcoming legislation aims to update the existing Network and Information Systems (NIS) Regulations 2018. The bill seeks to expand the scope of regulated sectors, bolster the authority of regulators, and mandate more comprehensive incident reporting. Its goal is to ensure that critical infrastructure and digital services are secure against evolving cyber threats. GOV.UK
- GovAssure Programme: Launched in 2023, GovAssure is a cybersecurity regime for UK government departments. It mandates regular assessments using the National Cyber Security Centre's Cyber Assessment Framework to ensure robust cybersecurity practices across public sector organisations.

These regulatory initiatives highlight the UK's commitment to strengthening its cyber defences. Organisations should regard compliance not merely as a legal obligation but as an opportunity to enhance their security frameworks and build resilience against potential threats. Businesses must demonstrate that they are actively managing cybersecurity risks and responding to incidents appropriately. Rather than perceiving compliance as a burden, organisations can leverage it as an opportunity to fortify security frameworks and bolster resilience.
Final Thoughts: A Proactive Approach to Cybersecurity
The evolving threat landscape presents challenges, but it also provides an opportunity for CISOs to drive meaningful change within their organisations. By learning from recent incidents, prioritising security awareness, and investing in the right technologies, businesses can build a security posture that’s both resilient and adaptable.
