Feature or Attribute Extraction for Intrusion Detection System using Gain Ratio and Principal Component Analysis (PCA)

Efficient Intrusion Detection Using Principal Component Analysis

Most current intrusion detection systems are signature based ones or machine learning based methods. Despite the number of machine learning algorithms applied to KDD 99 cup, none of them have introduced a pre-model to reduce the huge information quantity present in the different KDD 99 datasets. We introduce a method that applies to the different datasets before performing any of the different ...

Feature Extraction Using Genetic Algorithm Based Principal Component Analysis

Intrusion Detection System Using PCA and Kernel PCA Methods

The network traffic data used to build an intrusion detection system is frequently enormous and redundant with important useless information which decreases IDS efficiency. In order to overcome this problem, we have to reduce as much as possible this meaningless information from the original high dimensional data. To do this, we have compared the performance of two features reduction techniques...

An Approach for Reducing the Computational Complexity of LAMSTAR Intrusion Detection System using Principal Component Analysis

The security of computer networks plays a strategic role in modern computer systems. Intrusion Detection Systems (IDS) act as the ‘‘second line of defense’’ placed inside a protected network, looking for known or potential threats in network traffic and/or audit data recorded by hosts. We developed an Intrusion Detection System using LAMSTAR neural network to learn patterns of normal and intrus...

Measuring gas demand security using Principal Component Analysis (PCA): A case study

Safeguarding the energy security is an important energy policy goal of every country. Assuring sufficient and reliable resources of energy at affordable prices is the main objective of energy security. Due to such reasons as special geopolitical position, terrorist attacks and other unrest in the Middle East, securing Iran’s energy demand and increasing her natural gas exports have turned into ...
