Abstract
There is provided a method comprising: generating and sharing an initial value of an integrity token between an endpoint node and a security backend computer, collecting data at the endpoint node, wherein dissimilar data types are aligned as input events, generating a new integrity token every time a new input event is written to a local repository of the endpoint node, wherein the new integrity token is generated based on the new input event and a prior integrity token that was generated prior to the new integrity token, removing the prior integrity token generated prior to the new integrity token from the endpoint node each time a new integrity token has been generated, and sending one or more input events with the new integrity token to the security backend computer for enabling the security backend computer checking integrity of the data received from the endpoint.
