Worldwide it is more and more common that the systems of the national governance, army, education etc. are retooled to open source systems - mainly because of the economical operation. The purpose of the article is to analyze and compare - in the aspects of security and performance - the abilities of the Web server ensured by the newest version of the most commonly spread closed source operation system...
Web applications support more and more our daily activities, it's important to improve their reliability and security. The content which users input to Web applications' server-side is named un-trusted content. Un-trusted content has a significant impact on the reliability and security of Web applications, so detecting the un-trusted variables in server-side program is important for improving the...
Security of Web servers has become a sensitive subject today. Prediction of normal and abnormal request is problematic due to large number of false alarms in many anomaly based intrusion detection systems (IDS). SS-IDS derives automatically the parameter profiles from the analyzed data thereby generating the statistical signatures. Statistical signatures are based on modeling of normal requests and...
Cross Site Scripting (XSS) is one of the worst vulnerabilities that allow malicious attacks such as cookie thefts and Web page defacements. Testing an implementation against XSS vulnerabilities (XSSVs) can avoid these consequences. Obtaining an adequate test data set is essential for testing of XSSVs. An adequate test data set contains effective test cases that can reveal XSSVs. Unfortunately, traditional...
We developed a model to investigate the phenomenon of whitewashing in peer-to-peer (P2P) systems. A white washer is a node that leaves the network and re-joins using a different identity. Whitewashing is a common problem in P2P systems and is a difficult to manage properly for reputable systems. The paper discusses the definition and properties of trust, formally represents the node by the labeled...
Penetration testing is widely used to help ensure the security of web applications. It discovers vulnerabilities by simulating attacks from malicious users on a target application. Identifying the input vectors of a Web application and checking the results of an attack are important parts of penetration testing, as they indicate where an attack could be introduced and whether an attempted attack was...
