This Recommendation identifies aspects to be evaluated before delivering a security service based on distributed ledger technology (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.
