Presentation abstracts
AppSensor: Real Time Defenses against Application Worms and Malicious Attackers

ABSTRACT

The OWASP AppSensor project was created to address the lack of defensive systems within applications. Regardless if an application is secure or insecure, malicious actions should be recorded, analyzed and responded to by the system. It is unacceptable to allow an attacker unrestricted attack attempts against the application. Eventually a known or unknown vulnerability will be discovered by the attacker and exploited. AppSensor monitors attack activity and takes defensive actions such as throttling or disabling the malicious account. Behavior analysis techniques are also employed to identify application worms. Defensive techniques are described which provide real-time containment of the application worm while maintaining overall system availability.

SPEAKER BIO

Michael Coates is a Senior Application Security Engineer for Aspect Security and has performed numerous penetration assessments, security code reviews, and security training sessions for leading corporations worldwide. Michael is the creator and leader of the AppSensor project and is completing a Masters Degree in Computer Security from DePaul University. In past years, Michael assessed the security of GSM and WiMAX telecommunication networks, application and network systems for financial institutions and performed social engineering testing.

Assessing Thick Web Applications

ABSTRACT

Recently, web applications have been pushing more application to the browser and in many cases entirely out of the browser. Technologies for pushing richer content to the client, such as ActiveX, Flash, Google's NaCl and browser extensions, can frustrate efforts to assess an application. Occasionally, these technologies remove the browser entirely to create a semi thick client that uses standard web application methodologies and transport methods.

While a few framework specific tools have begun to mature, they are geared toward debugging an application for quality assurance purposes rather than security assessment. A solution for many of these technologies is simply repurposing and reinventing some of the old application assessment tool chain: the debugger. A new generation of scriptable debuggers is showing up. Using these tools allows increased automation and visibility into the newest thick web application frameworks.

SPEAKER BIO

Timur Duehr is a Security Consultant at Matasano Security and a graduate student in Mathematical Computer Science at the University of Illinois at Chicago. Timur is one of the lead developers of Ragweed, a scriptable debugger written in Ruby for win32, OSX and linux applications.

Webapps In Name Only Thomas Ptacek, Matasano Security

Where modern network architecture meets legacy application design, we get "The Port 80 Problem": vendors wrapping every conceivable network protocol in a series of POSTs and calling them "safe". These "Webapps In Name Only" are a nightmare for application security specialists.

In this talk, we'll discuss, with case studies, how tools from protocol reverse engineering can be brought to bear on web application security, covering the following areas:

- Locating and Decompiling Java and .NET Code - Structure and Interpretation of Binary Protocols in HTTP - Protocol Debugging Tools - Web App Crypto Tricks

Token-less strong authentication for web applications: A Security Review Cory Scott, ABN AMRO

A short presentation on the threat models and attack vectors for token-less schemes used to reduce the risk of password-only authentication, but yet do not implement "true" two-factor technologies for logistical costs or user acceptance reasons. We'll go over how device fingerprinting and IP geo-location work and discuss the pros and cons of the solutions.
