Comment on the NHS 111 service cyberattack

August 2022 by Sunil Ravi, Chief Security Architect at Versa Networks

The comment by Sunil Ravi, Chief Security Architect at Versa Networks, on the cyberattack which hit Advanced and affected the NHS 111 service.

“Supply chain attacks have grown significantly over the last two years, and the latest attack against the NHS through one of its suppliers, shows that some organisations are in a constant battle with cyber criminals.

Many healthcare providers have adopted online channels in recent years to provide patient care and services. While going digital makes a number of services more convenient, it also increases device complexity on networks and exposes them to attacks. Downtime or delays in the network such as the ones experienced by the NHS, means that emergency services cannot run at their full capacity, which ultimately, can make the key difference in life-and-death circumstances.

Healthcare organisations like the NHS, have already suffered enough with delays and services made unavailable during the COVID-19 pandemic. They cannot afford for cyberattacks to be their downfall. However, implementing security procedures which could also hamper connectivity won’t work either. Healthcare organisations need the uptime to provide crucial patient care and services, whilst also being safe in the knowledge that their networks are secure.

Therefore, organisations need a solution which provides the best possible security whilst also ensuring high networking performance – this is where technologies that integrate the two, like SASE, can help. SASE ensures that all endpoints are visible, and networks are segmented, meaning security teams can quickly detect, locate and mitigate the impact of cyberattacks, and prevent downtime or disruption to critical services.”
