What is the false-positive rate for the detection of anomalies?
The finally safe system detects anomalies with learned data as basis. Overall, the detection of anomalies is to 99,9% mathematically correct. This means that the false-positive rate is almost 0%.
For the particular question, which anomalies or hidden tunnels can be consired as a threat, it is not possible to specify a probability, because each anomaly / tunnel must be regarded as an individual case. This requires additional knowledge about the respective network as well as a professional evaluation.
