With the development of database technology and the popularity of Internet, the database applications have been increasingly widespread; we must face on some serious database security. The database system is the aggregates of the message, and it is the core components of the computer message system. The security of database is very important; it is related to the success of enterprise and national...
Aimed at the intrusion behaviors are characterized with uncertainty, complexity, diversity and dynamic tendency and the advantages of wavelet neural network (WNN), an intrusion detection method based on WNN is presented in this paper. Moreover, we adopt a algorithm of reduce the number of the wavelet basic function by analysis the sparseness property of sample data which can optimize the wavelet network...
Denial of Service is becoming a growing concern. As our systems communicate more and more with other that we know less and less, they become increasingly vulnerable to hostile intruders who may take advantage of the very protocols intended for the establishment and authentication of communication to tie up our resources and disable our servers. Since these attacks occur before parties are authenticated...
This paper presents a model of intelligent content filtering model to resolve the current network security audit system in filtering the information deficiency. First of all, in accordance with the characteristics of network security audit system, as well as the advantages and disadvantages of content filtering methods commonly, this paper choose suitable filter method, and then, optimize the filter...
A new model of network security assessment is proposed in this paper. A single IT entity is evaluated through EAL; The composite IT entities are evaluated by CAP. The model analyzes the security value of network elements, and adopts the Geometric mean method to determine the security value of the entire network. The effectiveness of this method is validated through the evaluation of a practical system.
The problems related to security for network systems are relative to the design of network architectures, which is typically based on open standards. Monitoring tools based on pattern recognition or behavioral analysis is typically used to ensure network security. SNORT is one such tool which is based on pattern recognition. SNORT alerts system administrators whenever it receives packets of information...
Distributed denial of service (DDoS) attack is one of the latest and most powerful threats that have appeared to the Internet. The main aim of such attacks is to prevent access to resources by legitimate users for which they have authorization. In this paper, a novel flow-volume based DDoS detection approach (FVBA) is proposed, which deals with detection of variety of DDoS attacks by monitoring the...
