EXCHANGING AND ACTING ON SECURITY EVENTS AT AN ENTERPRISE USING PERMISSIONED BLOCKCHAIN

摘要

Various examples are disclosed for exchanging and acting on detected security events using permissioned blockchain. A unique identifier for a client device is obtained in response to a detected security event being identified. Security event data associated with the detected security event is sent to a plurality of nodes of a blockchain service, where the nodes are associated with a respective one of a plurality of computer security services and are configured to validate the security event data and endorse the security event data in response to predetermined criteria being satisfied. In response to the security event data being validated by the nodes, the security event data is published into the blockchain service as a block that is broadcasted to the nodes, where individual ones of the nodes are configured to store the security event data of the block in a local ledger.
