Denial of View Technique ID T0815 Tactic Impact (T0815) Denying this view may temporarily block and prevent operators from noticing a change in state or anomalous behavior. Adversaries may cause a denial of view in attempt to disrupt and prevent operator oversight on the status of an ICS environment. This may manifest itself as a temporary communication failure between a device and its control source, where the interface recovers and becomes available once the interference ceases. The environment’s data and processes may still be operational, but functioning in an unintended or adversarial manner.”]
