Security researchers at the MIT designed an Artificial Intelligence system called AI2 that is able to detect 85 percent of attacks. The system was tested on 3.6 billion pieces of data known as log lines which were generated by millions of users over a period of three months. The AI2 system first performs an automatic scan of the content with machine-learning techniques and then reports the results to human analysts. The greater the number of analyzes carried out by the system, the more accurate the subsequent estimates thanks to the feedback mechanism.”]
