Ransomware: How the NHS learned the lessons of WannaCry to protect hospitals from attack

The NHS aims to enhance its cyber security in the wake of the WannaCry ransomware attacks in 2017. As ransomware becomes an increasing concern, the health service is focused on making it harder for cyber criminals to exploit system vulnerabilities. Among the measures taken are alerting NHS Trusts to new security vulnerabilities and providing support to apply relevant patches. The NHS is also ensuring that there are system backups across the country, so networks can be restored without paying ransom to cyber criminals in case of an attack.
