Following news that a cyber-attack on a major IT provider of the NHS, Advanced, has been confirmed as a ransomware attack (NHS IT supplier held to ransom by hackers - BBC News), Erfan Shadabi, Cybersecurity Expert at comforte AG, explains further about attacks on healthcare providers:
Healthcare providers and related corporations – such as third-party service providers- are among the most highly regulated organizations in any market. The reason is obvious: they collect and handle some of the most sensitive personal data about an individual. The report that a major IT provider of the NHS has experienced a ransomware attack should trigger alarm bells within any similar provider. The best way to mitigate such cyberattacks is to safeguard sensitive records such as medical information through a data-centric approach. Data-centric methods such as tokenization replace sensitive data elements with tokens that maintain the analytic value of the data while obscuring the actual sensitive information itself. It becomes non-identifying and therefore worthless in the hands of threat actors, while remaining fully workable by the enterprise.
