An example operation may include one or more of receiving, by a validator node, candidate update code for installation on one of multiple networked ECUs of a vehicle as a target node, identifying one or more other ECUs on the network that communicate with the target node as impacted nodes, checking for known adverse conditions between the candidate update code and existing code of the impacted nodes, in the case an adverse condition is identified, preventing the update code from being installed on the target node, in the case no adverse condition is identified, and no adverse condition is identified by any peer validator node, allowing the update code to be installed on the target node, forming, by the validator node, a block containing information of the candidate update code and its installation disposition, and appending the block to a blockchain utilized by at least one of the peer validator nodes.

The method includes identifying, by one or more computer processors, incoming data related to a source. The method further includes identifying, by one or more computer processors, data related to a recipient of incoming data from the source. The method further includes determining, by one or more computer processes, a relationship between the source and the recipient of the incoming data from the source. The method further includes calculating, by one or more computer processors, a risk indicator associated with the incoming data from the source based upon the identified data related to the source, the identified data related to the recipient and the determined relationship between the source and the recipient. The method further includes sending, by one or more computer processors, a notification to the recipient, wherein the notification includes at least the calculated risk indicator.
