The threat from web Trojan in electric power systems (EPS) is complex, which perhaps infects computers, damage SCADA system, or even cause electricity fail. The paper presents the potential Trojan attack risks of EPS by analyzing the security architecture of power systems, such as firewall, intrusion detection system and intrusion prevention system. The paper analyzed some possible attack methods...
Hash tree based disk storage integrity protection suffers from performance penalty and possible losing of consistency. FI-Tree deploys a fixed-structure tree and applies incremental-hash to tree node updating to solve the difficulties of performance and consistency. The biggest advantage of FI-Tree comes from that: to allow tree nodes to be cached to optimize performance, it can maintain consistency...
Many previous genetic algorithm methods can get much better example results in KDD cup 99 dataset. In the real intrusion detection system, the software needs update the rule even everyday. In this paper, we expand previous work and present a fitness function, propose an efficient rule generator for denial of services of network intrusion detection. We use more chromosomes with relevant features and...
Rootkits Trojan virus, which can control attacked computers, delete import files and even steal password, are much popular now. Interrupt Descriptor Table (IDT) hook is rootkit technology in kernel level of Trojan. The paper makes deeply analysis on the IDT hooks handle procedure of rootkit Trojan according to previous other researchers methods. We compare its IDT structure and programs to find how...
Penetration testing is an important branch of network security evaluation, which aims at providing all-round investigation to find the vulnerabilities and security threats in systems and networks. Former penetration testing platforms lack the adaptability when applied to different types of systems or networks, and the manual tests which are prevailed in those platforms are usually long and complex...
