Blockchain
Blockchain excels in a limited set of cybersecurity applications, but its impact will likely be incremental rather than revolutionary, according to Raffael Marty, Forcepoint's vice president of corporate strategy.
Organizations often want an irrefutable record of when a user accessed critical data, and that record could be stored in the blockchain to ensure it's verifiable by everyone and can't be altered, Marty said. But when it comes to smart contracts – a computer protocol intended to digitally enforce the negotiation or performance of a contract – he doesn't see the security benefit provided by blockchain.
In addition, organizations need to be mindful of what information is being stored via blockchain since it becomes immutable, according to Heath Thompson, Forcepoint's SVP and General Manager, Commercial Security. Therefore, Thompson said anything that could be viewed as personally identifiable information under regulations such as GDPR shouldn't be stored in blockchain.
