The existing well-known network based intrusion detection/ prevention techniques such as the misuse detection technique, etc, are widely used. However, because the misuse detection based intrusion prevention system is proportionally depending on the detection rules, it causes excessive large false alarm which is linked to wrong correspondence. This study suggests an intrusion prevention system ...

IPv6 has enough IP addresses to solve the problem of lack of IP address space. However, there are many security problems to be concerned. The detection ability of current intrusion detection system is poor when given less priori knowledge. In this paper, we analyze the Least Squares Support Vector Machine (LS-SVM) algorithm and the working process of snort intrusion detection system. And then w...

In network security, Intrusion Detection System plays a reasonable supplementary role for the firewall. It improves the security and reliability of the computer and helps protect computers from network attacks. At present intrusion detection system analysis module uses the pattern matching technology. In this article, through analyzing the advantages and disadvantages of the main pattern matchi...

In this paper we discuss our research in developing intrusion detection software framework for modeling, simulation and detection computer system intrusion based on partially ordered events and patterns FEIIDS. The article describes problematic of intrusion detection systems and intrusions detection. We provide concrete design of developed framework based on intrusion signatures threats are mat...

In recent years, wireless ad hoc sensor network becomes popular both in civil and military jobs. However, security is one of the significant challenges for sensor network because of their deployment in open and unprotected environment. As cryptographic mechanism is not enough to protect sensor network from external attacks, intrusion detection system needs to be introduced. Though intrusion pre...

Intrusion detection system (IDS) is the process of monitoring events occurring in a computer or network and analyzing them for signs possible incidents, which are violations imminent threats violation security policies. An intrusion prevention (IPS) software that has all capabilities an can also attempt to stop incidents. If anomaly traffic pass through IDS would generate false positive means i...

With the rapid growth of computer networks during the past few years, security has become a crucial issue for modern computer systems. A good way to detect illegitimate use is through monitoring unusual user activity. This can be achieved with an Intrusion Detection System, which identifies attacks and reacts by generating alerts or by blocking the unwanted data/traffic. These systems are mainl...
