Schools across the United Kingdom are now being urged to sign up for a free cybersecurity service developed by experts within the nation’s security and intelligence services, aimed at safeguarding educational institutions from ransomware attacks and other online threats. The move seeks to protect schools and the sensitive data they hold, particularly as cyberattacks on the education sector continue to rise.
Ransomware incidents targeting schools can have devastating consequences. Not only do they disrupt students’ access to education and critical services, but they also pose a threat to vulnerable children by exposing sensitive information through extortion attempts. In response, the National Cyber Security Centre (NCSC), part of the UK’s signals and cyber intelligence agency GCHQ, announced the national rollout of its Protective Domain Name System (PDNS) for Schools service on Tuesday.
The PDNS for Schools service employs the same technology already used by central government agencies, emergency services, and the Ministry of Defence. It was developed by NCSC and is delivered in partnership with Cloudflare and Accenture. This technology prevents computers within school networks from connecting to known malicious domains, using a database built from intelligence sources only accessible to the security services. The system can block access to harmful domains within 30 minutes of their identification.
This nationwide protection initiative comes at a time when ransomware attacks targeting the education sector have reached alarming levels. Last year, 131 incidents were reported to the data protection regulator, and at least 47 schools were compromised in the first half of this year, resulting in data breaches involving personal information. Affected schools include institutions in London, West Sussex, and Leeds, including a school for children with special educational needs.
Ofqual, the UK’s qualifications and examinations regulator, has reported that over a third of schools experienced a cyber incident during the previous academic year, with some incidents taking weeks to resolve. As the risks grow, the NCSC’s deputy director for economy and society, Sarah Lyons, emphasized the critical need for cybersecurity in the education sector. “With a growing range of cyber threats, it has never been more important to protect our educational environments from online threats. The PDNS for Schools service offers a crucial layer of protection, helping schools defend against common online threats, at no cost,” Lyons stated.
Educational organizations across the UK can sign up for the PDNS for Schools service by having their DNS provider register through MyNCSC, ensuring that students and staff are better protected from online dangers.
