On the Efficiency of Mathematics in Intrusion Detection: The NetEntropy Case
نویسندگان
چکیده
NetEntropy is a plugin to the Orchids intrusion detection tool that is originally meant to detect some subtle attacks on implementations of cryptographic protocols such as SSL/TLS. NetEntropy compares the sample entropy of a data stream to a known profile, and flags any significant variation. Our point is to stress the mathematics behind NetEntropy: the reason of the rather incredible precision of NetEntropy is to be found in theorems due to Paninski and Moddemeijer.

Nowadays, Network Intrusion Detection Systems (NIDS) are widely used to provide full security on computer networks. IDS are categorized into two primary types, including signature-based systems and anomaly-based systems. The former is more commonly used than the latter due to its lower error rate. The core of a signature-based IDS is the pattern matching. This process is inherently a computatio...
متن کاملReal-Time intrusion detection alert correlation and attack scenario extraction based on the prerequisite consequence approach
Alert correlation systems attempt to discover the relations among alerts produced by one or more intrusion detection systems to determine the attack scenarios and their main motivations. In this paper a new IDS alert correlation method is proposed that can be used to detect attack scenarios in real-time. The proposed method is based on a causal approach due to the strength of causal methods in ...

Intrusion detection systems are responsible for diagnosing and detecting any unauthorized use of the system, exploitation or destruction, which is able to prevent cyber-attacks using the network package analysis. one of the major challenges in the use of these tools is lack of educational patterns of attacks on the part of the engine analysis; engine failure that caused the complete training, ...
