H-HIPS (Hardware- and Host-Based Intrusion Prevention System) is an IPS that can be used on UMPC (Ultra-Mobile PC) or PDA (Personal Digital Assistant). Because it has been achieved by using a FPGA (Field Programmable Gate Array), the use of the hardware resource for intrusion detections is limited. Additionally, the operation of low power consumption is very important. In this paper, a firewall unit...
The outbreak of worm is very frequent today. It has great impact on the society infrastructure and people's wealth security. A large number of experts have devoted themselves to the research of worm propagation modeling. Both deterministic model and stochastic model have been used in modeling worm spread. In this paper, we analyze the worm functional structure, and then propose a deterministic worm...
Based on this essay, we introduce the current network security technologies and problems. Also, we analyze the excellence and weakness of the firewall technologies, the intrusion detection and prevention technology in order to integrate the firewall technology and intrusion prevention technology, which can help to improve the real-time check, accuracy and recovery ability of the network security system.
Intrusion detection is an area of computer security that involves the detection of unwanted manipulations to computers and computer networks. An intrusion detection system is required to detect all types of malicious network traffic and computer usage that can not be detected by a conventional firewall. This security method is needed in todaypsilas computing environment because it is impossible to...
A honeypot is a type of information system that is used to obtain information on intruders in a network. When a honeypot is deployed in front of a firewall, it can serve as an early warning system. When deployed behind the firewall, it can serve as part of a defense-in-depth system and can be used to detect attackers who bypass the firewall and the intrusion detection system (IDS) or threats from...
