Not sure if this applies to DDoS, but a baseline ML method for security is outlier detection. For example, (1) you get a dataset that is mostly "good" data, with some "bad" data (2) you cluster it using something fast like k-means (3) data points are labelled as outliers if they fall further than some threshold from a cluster center.
