Identity Theft is a fraud, in which someone pretends to be someone else is order to steal money or get other benefits. To overcome the problem of Identity Theft an additional security layer relying on the verification of users, based on their keystroke dynamics is proposed. Additionally we suggest to continuously verify users based on their keystrokes and mouse dynamics. The motivation for such technology, its challenges and potential, will be discussed.

Cars are going wired and no one is going to stop it. Many car manufacturers already offer an on board computer that is an integral part of the car and communicates with the world over cellular links. This computer offers navigation, entertainment, phone, location and safety application among others. However this level of connectivity both to the car systems and to the world presents a new threat affecting car users privacy and driving safety. The presentation will discuss new car computing platforms, their security implications and propose mitigation methods.

Identity management is often driven by operational requirements rather than security requirements. The presentation will explore the security aspects of IdM as part of authentication and authorization. Among the issues discussed are: What security benefits can an IdM provide? What IdM types, techniques and methods best suit security requirements? And lastly what are the security pitfalls and disadvantages of IdM.

These include, among others, Web Application, WAFs, IDS, AV, Web Servers, Client-side browsers (including cellular devices), and Database.

Cross-site Scripting (XSS) has emerged as one of the most prevalent types of security vulnerabilities in web applications. Current defense mechanisms are mainly based on detecting malicious content on HTTP-requests using a negative security logic approach. This approach has known limitations, derived from the difficulty to define all the HTTP-request payload characteristics that may lead to XSS attacks. In this work we present a positive security logic approach to detect and prevent XSS attacks by verifying that every web-page sent back to the user's browser contains only "legal and original" code scripts inserted into the HTTP-response by the web application without being influenced by malicious input. Our results show that after a short learning period the XSS detector has zero false-positive and zero false-negative given our prototype limitations.

14:10-14:40 Identity Theft, Computers and Behavioral Biometrics

Robert Moskovitch, Deutsche Telekom Laboratories at Ben-Gurion University

Identity Theft is a fraud, in which someone pretends to be someone else is order to steal money or get other benefits. To overcome the problem of Identity Theft an additional security layer relying on the verification of users, based on their keystroke dynamics is proposed. Additionally we suggest to continuously verify users based on their keystrokes and mouse dynamics. The motivation for such technology, its challenges and potential, will be discussed.

14:40-15:30 The Bank Job: A hacker’s day of work - Exploiting a vulnerable web site

Adi Sharabani , IBM

In this presentation we will show how severe a Cross-Site Scripting vulnerabilities are. We will build a step-by-step working exploit code for an XSS vulnerability found in an online banking site to hijack user sessions, transfer money and cover the traces. The money will be shared among the audience.

The presentation does not require any prior knowledge, but it is also aimed for technical people.

15:30-16:00 IdM: the missing security link

Avi Douglen

Identity management is often driven by operational requirements rather than security requirements. The presentation will explore the security aspects of IdM as part of authentication and authorization. Among the issues discussed are: What security benefits can an IdM provide? What IdM types, techniques and methods best suit security requirements? And lastly what are the security pitfalls and disadvantages of IdM.
