Intrusion protection system is a security system that stop abnormal traffics through automatic activity by finding out attack signatures in network. Unlike firewall or intrusion detection system that defends passively, it is a solution that stop the intrusion before intrusion warning. The security performance of intrusion protection system is influenced by security auditability, user data protection, security athentication, etc., and performance is influenced by detection time, throughput, attack prevention performance, etc. In this paper, we constructed a convergence performance evaluation model about software product evaluation to construct the model for security performance evaluation of intrusion protection system based on CC(Common Criteria : ISO/IEC 15408) and ISO international standard about software product evaluation.

Information can be leaked, changed, damaged and illegally used regardless of the intension of the information owner. Intrusion Detection Systems and Firewalls are used to protect the illegal accesses in the network. But these are the passive protection method, not the active protection method. They only react based on the predefined protection rules or only report to the administrator. In this paper, we develop the intrusion detection and protection system using Netfilter framework. The system makes the administrator's management easy and simple. Furthermore, it offers active protection mechanism against the intrusions.

Since IT industries grew, The information security of both individual and company has come to the front. But, nowadays, It is very hard to satisfy the diversity of security Protection Profile with simple Intrusion Detection System, because of highly developed Intrusion Skills. The Intrusion Detection System is the system that detects, reports and copes with of every kind of Intrusion actions immediately. In this paper, we compare the concept of IDS PPs and analyze the threat of PP.

Intrusion detection system is a means of security that detects abnormal use and illegal intension in advance in real time and reenforce the security of enterprises. Performance of intrusion detection system is judged by information collection, intrusion analysis, intrusion response, review and protection of intrusion detection result, reaction, loss protection that belong to the area of intrusion detection. In this paper, we developed a evaluation model based on the requirements of intrusion detection system and ISO international standard about software product evaluation.

The breakthrough in computer and network has facilitated a variety of information exchange. However, at the same time, malicious users and groups are attacking vulnerable systems. Intrusion Detection System(IDS) detects malicious behaviors through network packet analysis. However, it has a burden of processing a large amount of packets in a short time. Therefore, in order to solve these problem, we propose a network intrusion detection system that operates at kernel level to improve detection performance at user level. In fact, we confirmed that the network intrusion detection system implemented at kernel level improves packet analysis and detection performance.

This paper moses a method to solve the weakness in Snort, the network based intrusion detection system. Snort which is the rule-based intrusion detection system dose not supports a protection method for their own rules which are signatures to detect intrusions. Therefore the purpose of this paper is to provide a scheme for protecting rules. The system with the proposed scheme could support integrity and confidentiality to the rules.

As the electronic commercial transaction is being transacted by contents which can get an illegal intrusion from the outside, we sincerely require security for them. We must consider a protection countermeasure about intrusion from protection of the passive form to protection intrusion of the active one. So the security is required against hackers illegality intrusion into the contents. As soon as the intrusion happens about the contents, the tools providing the monitor of contents are required to minimize the damage to the systems. Modified web contents detection system in this paper prevents the loss of resources and manpower required through individually monitoring on the web. Also, this paper offers rapid support of security that it analyzes the weakness of contents security of the web environment and the cause of the problem with the leakage of information. So this system has the pur pose of protecting the weakness of contents security and the leakage of information.

Frequent outbreak of intrusion of private information is occurring recently not only at portal sites but also in electronic information service of public agencies. Due to these intrusions, it is observed that the citizens tend to avoid providing their private information even to the service for public agencies. Therefore, the object of this research can be explained as demonstrating the influence of the intention of provision for private information to foster the selectronic information ervice of the public agencies. In order to achieve this, this research intends to demonstrate how the experience of the intrusion of the private information affects the concern about the privacy and how the information factor from the public electronic information service has influence on the reliability toward the public. The results showed that the experience of intrusion of privacy, awareness of the danger of privacy, and the sense protection of the information from the manager at public agencies have direct influence on the concern of privacy. Meanwhile, it has been verified that the awareness of information protection of a manager, the systemicity of information protection, and the surveillance and punishment of information protection have influence on the reliability of public agencies.

Wind Driven Rain (WDR) poses a significant threat to the building environment, especially in hurricane prone regions by causing interior and content damage during tropical storms and hurricanes. The damage due to rain intrusion depends on the total amount of water that enters the building; however, owing to the use of inadequate empirical methods, the amount of water intrusion is difficult to estimate accurately. Hence, the need to achieve full-scale testing capable of realistically simulating rain intrusion is widely recognized. This paper presents results of a full-scale experimental simulation at the NHERI Wall of Wind Experimental Facility (WOW EF) aimed at obtaining realistic rain characteristics as experienced by structures during tropical storms and hurricanes. A full-scale simulation of rain in strong winds would allow testing WDR intrusion through typical building components. A study of rain intrusion through a sliding glass door is presented, which accounted for the effects of multiple wind directions, test durations and wind speeds; configurations with and without shuttering systems were also considered. The study showed that significant levels of water intrusion can occur during conditions well below current design levels. The knowledge gained through this work may enhance risk modeling pertaining to loss estimates due to WDR intrusion in buildings, and it may help quantify the potential reduction of losses due to the additional protection from shuttering systems on sliding glass doors during winds.
