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...
The application of network computing technology, more and more widely, its security is particularly important to the emergence of trusted computing research for the security of network computing application technology research has provided new opportunities. In this paper, the credibility of Web-based computing environment, the structure of thought and its implementation model.
Situational assessment is significant for host-level security. Most existing approaches are generally limited to network security that is different from host-level security. In this paper, we introduce an approach to assess host security. Analyzing process and file behaviors, we propose a series of security indices, based on which we compute the value of process situation (PS) and file situation (FS)...
In the Age of Information, network education pays more attention to the application of IT technology and the training of talents, which makes learning more of customization and of opening up. In order to better enable learners to go beyond the limitations of space and time to acquire knowledge; in order to provide excellent learning environment for greater freedom and greater choice of learning activities...
Stream Control Transmission Protocol (SCTP) is a new transport layer protocol that is due to replace TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols in future IP networks. Currently, it is implemented in such operating systems like BSD, Linux, HP-UX or Sun Solaris. It is also supported in Cisco network devices operating system (Cisco IOS) and may be used in Windows....
About the risk evaluation of network security, a new assessment method based on Nonlinear Principal Component Analysis (NLPCA) is given. The principle and process of NLPCA-RBF is introduced in detail. At last, its superiority is indicated by example. It not only can reduce the dimension of input vector, but also can reserve the nonlinear characteristic of the network by nonlinearity. It is a new evaluation...
The following topics are dealt with: power systems; media processing; circuits; wireless communications; computational intelligence; renewable energy sources; wired networks; pattern recognition; computing architectures; software systems; database systems; signal processing; power electronics; optical communication; VLSI systems; traffic control; network security; and design automation.
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...
Intrusion detection systems monitor computer networks looking for evidence of malicious actions. Networks are complex systems, and a comprehensive intrusion detection solution has to be able to manage event streams with different content,speed, level of abstraction, and accessibility. Therefore, it is necessary to distribute intrusion detection sensors across multiple protected networks, manage their...
