Summary:
|
Distributed ledger technology (DLT) has features include immutability, data sharing, decentralization and tamper-resistance. Certain security services can benefit from the decentralized nodes of DLT to solve problems such as single point of failure, bottleneck performance and tampering.
This Recommendation identifies aspects to be evaluated before delivering a security service based on DLT and provides examples to implement four security services which could be delivered based on DLT, namely:
• DLT-based public-key certificate management;
• DLT-based software defined perimeter;
• DLT-based threat intelligence sharing; and
• DLT-based security audit.
