A gunshot detection system provides anti-tampering protection for gunshot sensor units and a control panel. The control panel monitors for tampering events, including monitoring for changes to configuration settings. When the settings are changed, even by an authorized user, the control panel generates a tampering alert and sends the alert to an operator of the control panel and/or administrators for the gunshot detection system. A similar notification might also occur when a sensor is taken offline or when an anti-tamper sensor on a housing of the gunshot sensor unit detects manipulation or opening of the housing. The control panel also monitors for tampering using machine certificates associated with the gunshot sensor units. In one example, the gunshot sensor units sign event data using the machine certificates and an arbitrary reference number known to the control panel. The control panel then verifies the signed event data to detect tampering events.
