In recent news, the NHS has been severely impacted by a ransomware cyber attack. This once again highlights the vulnerability of critical infrastructure to cyber threats. In this episode of ITSPmagazine, Marco Ciappelli and Sean Martin dive into this alarming incident while at the InfoSecurity Europe event in London, engaging with a panel of esteemed professionals in the field of information security.
One of the significant themes that emerged from the conversation is that cybercrime is no longer the domain of rogue teenage hackers working from their basements. As Brian Honan emphasized, cybercriminals today are often part of organized crime syndicates involved in drug trafficking, arms dealing, and human trafficking. They are driven by financial gain and are willing to go to great lengths to achieve their goals.
This particular incident affected NHS pathology services, causing surgeries and blood transfusions to be canceled or postponed, directly impacting patient care. Suk Paul pointed out that this kind of attack is not isolated. Since the conflict in 2022, the UK has witnessed a rise in cyber-attacks on public infrastructure, including hospitals and universities. He stated that the human intelligence element is crucial in identifying the techniques and methods used in such attacks.
The conversation also shed light on the complexity of managing third-party supply chain risk. Heather Lowrie suggested considering cybersecurity as a business enabler and not just a technical issue. She stressed the need for robust communication and collaboration between internal teams, external partners, and even at the board level to create a resilient cybersecurity posture.
To this end, Tim Grieveson echoed the importance of having a security leader with excellent communication skills who can align security strategies with business outcomes. This alignment is particularly essential in critical sectors like healthcare, where the focus is on maintaining patient-centric care.
Furthermore, Daniel Lattimer highlighted the challenges faced by the NHS in funding cybersecurity measures. He mentioned that while the NHS has made strides in improving its cybersecurity capabilities, there is still a dilemma of prioritizing between lifesaving patient care and investing in cybersecurity. More specific guidance and a legislative approach similar to US standards could help in achieving minimum security standards.
Brian Honan described the importance of legislative measures like the EU's Digital Operations Resilience Act (DORA) and the Network and Information Security Directive (NIS2), which focus on resilience in critical infrastructure. The key is not just to prevent cyber-attacks but to ensure continuity of services during and after an attack.
During the discussion, a repeated point was the inevitability of cyber incidents and the need for preparation and response. Tim Grieveson stressed the necessity of identifying critical assets and vulnerabilities, communicating risks to the board, and developing a clear response plan. He pointed out that it is not just about the technical aspects but also about storytelling and helping the organization understand the real-world implications of cyber risks.
The significance of cross-sector collaboration was also highlighted. Heather Lowrie noted that cyber threats are a societal challenge, not limited to individual organizations or sectors. Therefore, collective preparation and response are crucial for building resilience against cyber threats. She called for more exercises within and across sectors to prepare teams for real-world events.
Lastly, the episode discussed the ethical dilemma of paying ransoms. Brian Honan strongly advocated against paying the ransom, citing the lack of guarantee that systems would be restored securely and the need to rebuild trust in affected devices. Instead, the focus should be on robust preparation and managing supply chain security. In conclusion, this episode underscored the pervasive threat of cyber-attacks on critical infrastructure and the multifaceted approach needed to tackle these challenges.
