New Sequential Methods for Detecting Portscanners
Xinjia Chen
In this paper, we propose new sequential methods for detecting port-scan attackers which routinely perform random "portscans" of IP addresses to find vulnerable servers to compromi…
Estimating Traffic Parameters with Rigorous Error Control
Xinjia Chen
To perform a queuing analysis or design in a communications context, we need to estimate the values of the input parameters, specifically the mean of the arrival rate and service t…
Probabilistic Robustness Analysis -- Risks, Complexity and Algorithms
Xinjia Chen, Kemin Zhou, Jorge L. Aravena
It is becoming increasingly apparent that probabilistic approaches can overcome conservatism and computational complexity of the classical worst-case deterministic framework and ma…
A Statistical Theory for the Analysis of Uncertain Systems
Xinjia Chen, Kemin Zhou, Jorge L. Aravena
This paper addresses the issues of conservativeness and computational complexity of probabilistic robustness analysis. We solve both issues by defining a new sampling strategy and…
