The ventilator and the Service PC lack sufficient audit logging capabilities to allow for detection of malicious activity and subsequent forensic examination. An attacker with access to the ventilator and/or the Service PC could, without detection, make unauthorized changes to ventilator settings that result in unauthorized disclosure of information and/or have unintended impacts on device performance.
When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.
