How OWASP Works and Guided Tour of OWASP Projects Speaker: Dinis Cruz

This presentation will focus on my experience in getting things done at OWASP, what resources are available and what types of initiatives should the local chapters be doing. In addition to a quick overview of a number of key OWASP projects, this talk will also provide a tutorial on how the OWASP WIKI (MediaWiki based) can be used as a database (using the MediaWiki templates technology)

Using the O2 Platform to Consume OWASP projects

Speaker: Dinis Cruz

This presentation will focus on how to consume the OWASP Wiki and a number of OWASP projects using the OWASP O2 Platform. The O2 Platform has powerful technology and capabilities for both BlackBox and WhiteBox analysis and this presentation will provide examples on how to use O2 with: WebGoat, WebScarab, Code Crawler, Dir Buster, Testing Guide, Code Review Guide and OpenSAMM

The O2 Platform is focused on automating application security knowledge and workflows. It is specifically designed for developers and security consultants to be able to perform quick, effective and thorough 'source-code-driven' application security reviews (BlackBox + WhiteBox). In addition to the manual findings created/discovered by security consultants, the OWASP O2 Platform allows the easy consumption of results from multiple OWASP projects and commercial scanning tools. This allows security consultants to find, exploit and automate (via Unit Tests) security vulnerabilities usually dismissed by the community as impossible to find/recreate. More importantly, it provides the Security Consultants a mechanism to: a) 'talk' with developers (via UnitTest), b) give developers a way to replicate + "check if it's fixed" the vulnerabilities reported and c) engage on a two-way conversion on the best way to fix/remediate those vulnerabilities.

Dinis Cruz is a Security Consultant based in London (UK) and specialized in: ASP.NET/J2EE Application Security, Application Security audits and .NET Security Curriculum Development.

For the past years Dinis has focused on the field of Static Source Code analysis, from May 2007 to Dec 2009 he worked as a independent consultant for Ounce Labs (bought by IBM in July 2009) where during active security engagements using Ounce's technology he developed the Open Source codebase which now is the foundation of the OWASP O2 Platform.

Dinis is currently focused on making the O2 Platform the industry standard for consuming, instrumenting and data-sharing between the multiple WebAppSec tools, the Security consultants and the final developers.

Dinis is a also active trainer on .Net security having written and delivered courses for IOActive, Foundstone, Intense School and KPMG (at multiple locations including BlackHat), and has delivered a number of presentations and keynote speeches at multiple OWASP and Security related conferences

At OWASP, Dinis is the leader of the OWASP O2 Platform project, member of the OWASP Global Projects Committee, chair of the OWASP Connections Committee and member of the OWASP Board

Protecting Your Applications from Backdoors:

How to Secure Your Business Critical Applications from Time Bombs, Backdoors & Data

Speaker: Clint Pollock from Veracode

With the increasing practice of outsourcing and using 3rd party libraries, it is nearly impossible for an enterprise to identify the pedigree and security of the software running its business critical applications. As a result backdoors and malicious code are increasingly becoming the prevalent attack vector used by hackers. Whether you manage internal development activities, work with third party developers or are developing a COTS application for enterprise, your mandate is clear- safeguard your code and make applications security a priority for internal and external development teams. In this session we will cover; Prevalence of backdoors and malicious code in third party attacks Definitions and classifications of backdoors and their impact on your applications Methods to identify, track and remediate these vulnerabilities

Same Origin Policy

Presentations:

- Same Origin Policy slide deck

- Presentation on the Rendezvous toolset

Same origin policy is a simple and important security policy which protects millions of users on the web. Often times the policy is over simplified and there is a misconception that there is one consistent policy being used across all web technologies. Unfortunately this can’t be further from the truth. Different browser brands, RIA plugins, various scripting languages and features within the browser environment have their own interpretation of the same origin policy. Not understanding the subtle differences can be catastrophic to web security. This presentation tries to summarize the deltas in the same origin policy. This is also a call for action to involve the community to more comprehensively document the policies.

Hidetake Jo is part of the Trustworthy Computing team in Office. He works with teams throughout Office to identify threats and ways to mitigate those threats, he also gets to break stuff. Hidetake has written many penatration testing tools that are used throughout Microsoft.

Open Software Assurance Maturity Model (OpenSAMM)

Presentation:

Slide deck can be found here

The Open Software Assurance Maturity Model (SAMM) (http://www.opensamm.org/) is a flexible and prescriptive framework for building security into a software development organization. Covering more than typical SDLC-based models for security, SAMM enables organizations to self-assess their security assurance program and then use recommended roadmaps to improve in a way that's aligned to the specific risks facing the organization. Beyond that, SAMM enables creation of scorecards for an organization's effectiveness at secure software development throughout the typical governance, development, and deployment business functions. Scorecards also enable management within an organization to demonstrate quantitative improvements through iterations of building a security assurance program. This workshop will introduce the SAMM framework and walk through useful activities such as assessing an assurance program, mapping an existing organization to a recommended roadmap, and iteratively building an assurance program. Time allowing, additional case studies will also be discussed. OpenSAMM is an open a free project and has recently been donated to the Open Web Application Security Project (OWASP) Foundation. For more information on OpenSAMM, visit http://www.opensamm.org/.

The Microsoft Anti-Cross-Site Scripting Library

The Microsoft Anti-Cross-Site Scripting Library V3.0 (Anti-XSS V3.0) is an encoding library designed to help developers protect their ASP.NET web-based applications from XSS attacks. It differs from most encoding libraries in that it uses the white-listing technique — sometimes referred to as the principle of inclusions — to provide protection against XSS attacks. This approach works by first defining a valid or allowable set of characters, and encodes anything outside this set (invalid characters or potential attacks). The white listing approach provides several advantages over other encoding schemes. The following are some new features of Anti-XSS library v3.0. In this session, we will learn in-depth how Anti-XSS works and learn more about its new features.
 * An expanded white list that supports more languages
 * Performance improvements
 * Performance data sheets (in the online help)
 * Support for Shift_JIS encoding for mobile browsers
 * Security Runtime Engine (SRE) HTTP module
 * A sample application

Anil Kumar Revuru currently works for Information Security Tools team in Microsoft as Senior SDE where he is responsible for architecting security tools. In his previous life at Microsoft, Anil conducted security design reviews, threat modeling, and application and source-code assessments.

Speaker: Andre Gironda

Using ASVS with the Code Review Guide, Testing Guide, and Time Management

The OWASP Application Security Verification Standards, which defines four levels of web application security verification, lays down a framework for security architecture review. While the ASVS includes many requirements for controls, it does not suggest which tools, techniques, timeline or methodologies to utilize. The OWASP Code Review and Testing Guides provide the technical practices and suggest or hint at tools, but also lack the timeline and methodology necessary to complete an application penetration-test or SDLC integration project for proper application security hygiene.

This presentation will provide the 1000 foot view all the way down to the nitty gritty details of how to perform ASVS activities using OWASP resources, as well as some OWASP and non-OWASP tools (freeware or demoware). Example timelines for typical ASVS activities, including reports, will be discussed so that any sort of application security project can be scoped properly, delivered on-time, and within budget.

Andre Gironda is an application security specialist with a global security consulting firm providing IT security services to the Fortune 500 and financial institutions as well as U.S. and foreign governments. Prior to his current employment, Andre held a number of payment application security positions in addition to working for the largest online auction website.

Securing our Legacy - Responding to the call to provide practical security assurance

Every few months witnesses the release of a much-hailed report from an industry organization, think tank, or government agency calling for the software that runs our critical infrastructure to be secured. Making the call is easy, acting on it is only slightly harder, but succeeding at it is incredibly difficult. Of all of the tasks that must be undertaken to truly meet the call, the single biggest challenge I have seen companies face is delivering security assurance on legacy code. This talk will explore the challenge of providing security assurance for these old, little-loved, but heroic systems that power our lives. More importantly, It will include guidance for software development managers and engineers seeking to gain insight into the operation of their legacy systems, mechanisms by which important security assertions can be gathered, and practical methods for carrying out penetration tests and code reviews with the aim of providing a high degree of security assurance. Scott Stender is a co-founder and Partner of iSEC Partners, a strategic digital security organization.

Dynamic Taint Propagation: Finding Vulnerabilities Without Attacking

Dynamic taint propagation allows testers to find vulnerabilities without modifying existing functional tests. It enables true security testing inside a QA organization because it allows tight integration with existing QA infrastructure and solid usability for non-security experts. This talk will:


 * Explain how dynamic taint propagation works.
 * Show how to retrofit an existing executable to perform dynamic taint propagation.
 * Demonstrate how a tester can use a typical suite of functional tests to find vulnerabilities, without the need for malicious input or security expertise.
 * Compare this approach with the effectiveness of popular penetration testing tools--particularly those acquired by IBM and HP in 2007--when deployed in a QA environment.

The talk will conclude with a look towards the future of security testing in the QA environment and an overview of how multiple analysis techniques, both static and dynamic, can work together to provide better software assurance.

Concurrency Attacks in Web Applications

Modern web application frameworks are designed for developer productivity and performance. They are highly scalable, object-oriented, and can be used to create a usable web site in a matter of minutes.

Highly parallelized, object-oriented web application frameworks encourage programming practices that make managing state difficult for a typical programmer. In order to have a web application that is robust in a multi-threaded environment, the developer must carefully manage access to all resources that can shared by threads. Global variables, session variables, database access, and back-end systems are common examples of such resources, not to mention application-specific resources.

Concurrency flaws result when security-sensitive resources are not managed properly. As we have seen with almost every other prevalent class of security flaws, mistakes happen often when doing the right thing is difficult. To make things worse, concurrency flaws are often subtle and are identified only through difficult targeted testing.

This presentation will provide brief technical background against this class of flaw and enumerate testing techniques that help identify when flaws are present.

Bad Sushi - Beating Phishers at Their Own Game

This talk will expose tactics and tools used by phishers, show how easy it is to hack into servers that are used to perform phishing, demonstrate how easy it is so follow a phsisher's trail to find out how they share information on US Citizens including SSNs, bank account numbers, credit card numbers, ATM PINs, you name it.

Phishers usually setup their sites on servers they have compromised. In other words, the phishers have already done the hard work and it is easy to gain access to these servers. Due to the sheer volume of sites that need to be setup to perform a successful phish, phishers tend to be sloppy and leave traces everywhere.

This talk will expose some of the tactics and tools used by phishers. Actual walk-through of how compromised hosts were accessed to gain information about the phishers will be presented.

This talk will also show how easy it is to construct a trail from a compromised host to obtain information about individuals that is spewed on hacker message boards located outside the United States.

Billy Rios lives in a phish bowl and is constantly being sent emails from acquaintances all over the world. Billy has won the Internet lotto several times, is expecting large sums of abandoned money from a long lost relative in the Congo, and has received checks accidentally made out for 30,000 instead of 30 US dollars.

Speaker: Jon McClintock

Session management is one of the most overlooked areas of web application security, and yet it can also be the most challenging feature to get right in your web application. This talk will provide a brief overview of web session management, followed by an exposition into how several common web application frameworks implement session management, finishing with a discussion of several classes of vulnerabilities that can arise through poor session management.

Jon McClintock is a Senior Consultant for Leviathan Security Group, where he specializes in application security from design through implementation and into deployment.

Time: 6 o’clock.

Speakers:
 * Dinis Cruz (Chief OWASP Evangelist) - Directly from London, Dinis will be doing two presentations at this event:
 * Buffer Overflows on .Net and Asp.Net - One of the common myths about the .Net Framework is that it is immune to Buffer Overflows. Although this might be correct in pure managed and verifiable .Net code, large percentage of .Net and Asp.Net applications code is unmanaged code. In this talk Dinis will show the areas in .Net and Asp.Net applications that are vulnerable to Buffer Overflows (including the demo of a .Net Buffer Overflow Fuzzer).
 * OWASP, the Open Web Application Security Project - The Open Web Application Security Project (OWASP) is an open community dedicated to enabling organizations to develop, purchase, and maintain applications that can be trusted. All of the OWASP tools, documents, blogs, and chapters are free and open to anyone interested in improving application security. In this presentation Dinis will show the latest guides and tools from OWASP which should be part of every company's security efforts.
 * 0wning Vista's userland - The CAS / UAC missed opportunity, and what I think MS should had done - In this presentation Dinis will explore the missed opportunity by Microsoft to use technologies like .Net's CAS (Code Access Security) and Vista's UAC (User Access Control) to create secure and trustworthy userland environments that protect the user's assets. In the hope that might make a small difference, ideas and solutions for the future will also be presented.


 * Brad Hill (Senior Security Consultant with iSEC Partners), will be speaking on:
 * XML Digital Signature and Encryption: Use and Abuse - The WS-Security set of standards is on the threshold of ubiquitous deployment and XML applications have already taken over the world. This presentation looks at two underlying technologies, XML Digital Signature (XMLDSIG) and XML Encryption (XMLENC), their place in the Web Services stack and their applicability to non-SOAP XML applications. Beginning with a basic overview of the standards, we will uncover some surprising caveats and risks in the use of these technologies.
