1. A security event management system for an electronic connected network, comprising:
a public key infrastructure (PKI) subsystem configured to (i) generate a certificate for a connected device accessing the network, and (ii) provision the certificate for submission as a genesis transaction of a digital ledger, wherein the genesis transaction precedes all other transactions in the digital ledger, and wherein the all other transactions in the digital ledger may trace to the genesis transaction;
a trigger list in operable communication with the digital ledger; and
an event manager configured to (i) subscribe to the trigger list by defining at least one reportable event, related to the certificate, of which the trigger list is to advise the event manager, and (ii) receive, from the trigger list, a validation notification of the at least one reportable event,
wherein the validation notification is based on a spend condition of the certificate in a second transaction of the digital ledger within the all other transactions, and
wherein the spend condition indicates that the certificate is (i) renewed, or (ii) revoked.
