Description: 在现有的单层马尔科夫链异常检测模型基础上,提出一种崭新的两层模型.将性质上有较大差异的两个过程,不同的请求和同一请求内的系统调用序列,分为两层,分别用不同的马尔可夫链来处理.两层结构可以更准确地刻画被保护服务进程的动态行为,因而能较大地提高异常的识别率,降低误警报率.-In the existing single-layer Markov chain model for anomaly detection based on a new two-tier model. Will have a larger difference in the nature of the two processes, different requests and requests within the same system call sequence, sub- for a two-tier, respectively, in different Markov chain to deal with it. a two-tier structure can be more accurately portray the process of protection services by the dynamic behavior, which can greatly improve the identification of abnormal rate and reduce false alarm rate.

Description: 在网络异常检测中,为了提高对异常状态的检测率，降低对正常状态的误判率,本文提出一种基于量子粒子群优化算法训练小波神经网络进行网络异常检测的新方法。利用量子粒子群优化算法(QPSO)训练小波神经网络,将小波神经网络(WNN)中的参数组合作为优化算法中的一个粒子,在全局空间中搜索具有最优适应值的参数向量。- In order to improve the detection rate for anomaly state and reduce the false positive rate for normal state in the network anomaly detection, a novel method of network anomaly detection based on constructing wavelet neural network (WNN) using quantum-behaved particle swarm optimization (QPSO) algorithm was proposed. The WNN was trained by QPSO. Platform: |

Description: A new system for web attack detection is presented. It
follows the anomaly-based approach, therefore known and
unknown attacks can be detected. The system relies on a XML file
to classify the incoming requests as normal or anomalous. The
XML file, which is built from only normal traffic, contains a
description of the normal behavior of the target web application
statistically characterized. Any request which deviates from the
normal behavior is considered an attack. The system has been
applied to protect a real web application. An increasing number of
training requests have been used to train the system. Experiments
show that when the XML file has enough information to closely
characterize the normal behavior of the target web application, a
very high detection rate is reached while the false alarm rate
remains very low. Platform: |

Description: A taxonomy was developed by Axelsson to define the space of intrusion detection technology and classify IDSs.
The taxonomy categorizes IDSs by their detection principle and their operational aspects. The two main
categories of detection principles are signature detection and anomaly detection. The remainder of this paper
will compare the two categories of detection principles and describe a new type of anomaly detection based on
protocol standards. While the taxonomy applies to both host-based and network-based IDSs,
and more particularly protocol anomaly filters.
This is the result of research work done at Defcom Sweden, Stockholm. Platform: |
