Security corporations and researchers usually employ fuzzing techniques to find hiding bugs of programs. They collect millions of sample files to test target programs with mutating samples' byte randomly. However, it wastes lots of time and computation resources because the programs mostly repeat same paths with these samples. In the paper, we design a flexible and efficient method to calculate the...
With the rapid growth of Internet, the amount of malicious codes is exploding. Some security software vendors provide new cloud-based safeguard software for client users. These software, as part of Internet ware, consist of many modules with different functions and Internet behaviors. The Trojan scanning module, for instance, is based on cloud scanning function, which is achieved by collecting a large...
We present a honeynet-based collaborative defense framework and an improved highly predictive blacklisting algorithm is developed to generate highly personalized and predictive blacklists for individual networks by correlating historic attackers captured by honeynet deployed in each network. In this way, different networks can defend new attackers in a collaborative way because one network will notify...
IPv6 embraces various good features from the security perspective, but the improvements also bring us some new challenges for web content filtering. This paper presents a new framework of web content filtering in IPv6, which is helpful to purifying network environment. In this framework, using EM (Expectation maximization) algorithm, the active drift and self-learning mechanisms are proposed. Based...
Service Oriented Architecture (SOA) is a distributed software architecture model which use software resource as service on network, realize real platform independence and language independence. This article present summary architecture and designing idea of E-learning system of SOA which created based face service architecture, for example, online testing service registration operation, introduce...
So far, most existing protocol test generation methods are concentrated on complete protocol test, when aiming at some specific TP (test purpose),a mount of unnecessary test cases are generated because of the limitation of these methods. In this paper a method of TTCN (Tree and Tabular Combined Notation) test case generation based on TP description is proposed, in which according to non-formal TP,...
Aiming at automated security test on communication protocols, this paper proposes an automated manipulation mechanism of testing procedure based on FSM (Finite State Machine), and designs an automated packet generation mechanism based on a protocol template library. The practical experiments and applications show that the automated security testing platform of communication protocols based on this...
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...
Nowadays, technologies of information security have been attached more and more importance to and it's a critical problem to take measures to ensure the reliability of related trustworthy software such as secure operating systems (SOSs). Thereafter, it's always necessary for such systems to be taken complete and rigorous security test and evaluation among development team and/or by third-party security...
In Internet environment, software needs to be tested sufficiently before it is considered dependable. The operational profile based testing is an efficient way for both the reliability testing and the security testing. In practice, the two kinds of testing are often carried out separately to validate the dependability of the software, but it is resources consuming to develop the operational profile...
