Trusted verification of cybersecurity remediation

A system, comprising:

• one or more processors;
• and
• computer storage media having instructions stored therein, the instructions, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
• receiving a request for a validation of an infrastructure change from a user;
• retrieving event metadata for one or more infrastructure change events that are related to the infrastructure change from a decentralized secure ledger service;
• determining whether the event metadata of the one or more infrastructure change events indicate a completion of the infrastructure change;
• and
• generating a verification that a performance of the infrastructure change is complete in response to a determination that the event metadata indicate the completion of the infrastructure change.

A computer-implemented method, comprising:

• receiving event metadata at an audit function of an orchestration system for an infrastructure change event associated with an infrastructure change to an enterprise infrastructure of an enterprise;
• requesting a blockchain instance of a particular decentralized secure ledger from a decentralized secure ledger service that is maintained solely for the enterprise via the audit function;
• providing, via the audit function, a user identifier of a user that is responsible for the infrastructure change event to the decentralized secure ledger service;
• and
• sending, via the audit function, the event metadata for the infrastructure change event to the blockchain instance for storage with the decentralized secure ledger service in response to the decentralized secure ledger service authenticating the user identifier.
