Octo Consulting has created a proof of concept for the use of blockchain to help the Department of Health and Human Services secure log transactions.
The project's test case supports the objectives of the Department of Homeland Security-managed continuous diagnostics and mitigation program, which mandates federal agencies to provide log reports for security risk assessment, Octo said Tuesday.
Under a contract, the company used a blockchain ledger to compile logs into an encrypted list of transactions and show when a user creates, deletes or changes a file.
Octo noted it seeks to help HHS manage the department's security posture with the approach.
"With blockchain, every participant in the blockchain network can verify that their version of the truth matches everyone else’s," said Cesar Tavares, senior director for innovation and technology at Octo.
