Machine Learning-based Early Attack Detection Using Open RAN Intelligent Controller

, 2023
We design and demonstrate a method for early detection of Denial-of-Service attacks. The proposed approach takes advantage of the OpenRAN framework to collect measurements from the air interface (for attack detection) and to dynamically control the ...
