Exploiting Multi-class Probabilities for solving Network Security Anomalies using Supervised and UnSupervised Machine Learning Approaches

Abstract: In this talk we understand how the probabilities of a multi classification can be exploited to identify variations in sequence of events (SoE) that eventually leads to the identification of Network level attacks. This approach initially uses a supervised multi classification, following that with an unsupervised approach to identify anomalies; what we see are everyday, simple machine learning approaches, but powerful to identify network attacks and anomalies.
