FAST PORTSCAN DETECTION USING SEQUENTIAL HYPOTHESIS TESTING PDF

Fast Port Scan Using Sequential Hypothesis Testing performance near Bro; High speed; Flag as scanner if no useful connection; Detect single remote hosts. We develop a connection between this problem and the theory of sequential hypothesis testing and show that one can model accesses to local IP addresses as.
