Buffer overflow (BOF) is one of the major vulnerabilities that lead to non-secure software. Testing an implementation for BOF vulnerabilities is challenging as the underlying reasons of buffer overflow vary widely. This paper presents a novel method for BOF test for ANSI C language, which uses program instrumentation and mutation test technology to test the BOF vulnerabilities, on the basis of analyzing...
Trust propagation is now being studied in many areas (P2P, e-Business, etc.). Motivated by Web 2.0, researchers have put more concentration on trust prediction in online community. Recent years, some new ideas have emerged in trust propagation in order to acquire higher accuracy. However, to our best knowledge, there seems little research focuses on the interest of users in the trust web. In this...
Over the past few years, anomaly detection has been an increasing concern with the rapid growth of the network security. Hidden Markov model (HMM) has been applied in various methods in intrusion detection and proved to be a good tool to model normal behaviors of privileged processes, however, one major problem with this approach is that it demands excessive computing resources and costs a long model...
Essence of software testing is to choose a representative value (known as test case) from the input to perform the programs under test. The actual results of the programs will be checked to verify the consistency with the expected ones. If the results are different, it should take some correction and adjustment correspondingly. The existing method for test suite generation is mainly based on the test...
