This paper proposes a new idea for the educational reform of computer network curriculum in the finance and economics colleges, which can be performed relying on the predominance and unique features of the finance and economics colleges. The orientation of the computer network curriculum is for economic system, based on this, the corresponding course system is proposed, the characteristic teaching...
To elucidate the mechanism of the city conflagration automatic alarm network monitoring system, with reference to national standards and successful experience in the developed countries, and with the actual needs fire fighting management of the city conflagration. Based on the WEB search function, this system utilize the public or private networks to realize the comprehensive network monitoring for...
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.
The attack graph, a typical model-based method, is widely used in the field of network security evaluation. The biggest disadvantage of attack graph method is its exponential growth of the state space. This paper presents an efficient algorithm based on the malefactorpsilas access level vector in every host of the network to generate a reduced attack graph in polynomial compute complexity. In this...
Advances in Digital Technology have presented new challenges to both Industry and Law. Technology security experts are enhancing platforms security to protect enterprise and government from intrusions, whereas legal experts are adopting new techniques to investigate ldquoillegalrdquo breaches to systems and networks. This paper provides an overview of Digital Forensics methodologies, computer and...
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...
The 3 most important issues for anomaly detection based intrusion detection systems by using data mining methods are: feature selection, data value normalization, and the choice of data mining algorithms. In this paper, we study primarily the feature selection of network traffic and its impact on the detection rates. We use KDD CUP 1999 dataset as the sample for the study. We group the features of...
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...
Computer system security evaluation by using mean time-to-compromise criteria is presented in this paper. The outcome of the attack highly depends on the attacker skill level. The attacker skill level distribution must be estimated, normal skill level distribution in the skill group is suggested in the model. The article concludes with simulation results and evaluation of the chosen attacker skill...
