Web page malicious code detection is a crucial aspect of Internet security. Current Web page malicious codes detection work by checking for ??signatures??, which attempt to capture (syntactic) characteristics of the known malicious codes. This reliance on a syntactic approach makes such detectors vulnerable to code obfuscations, increasingly used by malicious codewriters, which alter syntactic prosperities...
Recently in-depth analysis of network security vulnerability must consider attacker exploits not just in isolation, but also in combination. The general approach to this problem is to compute attack graphs using a variety of graph-based algorithms. However, such methods generally suffer the exponential state space problem. Therefore, this paper brings forward two conceptions of vulnerability correlation...
Application features such as port numbers are used by network-based intrusion detection systems (NIDSs) to detect attacks coming from networks. System calls and the operating system related information are used by host-based intrusion detection systems (HIDSs) to detect intrusions towards a host. However, the relationship between hardware architecture events and denial-of-service (DoS) attacks has...
VPN(virtual Private network) provide a cost-effective means of connecting an organization and its partners when compared to the cost of a private network. A VPN provides a secure channel link over the Internet between project partners. This paper gives a brief introduction of fundamentals and implementations of the VPN, the comparison between characteristics and technologies of the traditional and...
