Orange is the New Purple: How and Why to Integrate Development Teams with Red and Blue Teams

Presented by: April Wright

Introducing a new paradigm for integrating developers with offensive and defensive teams to enhance SDLC. Learn how to integrate Offensive, Defensive, and Development Teams in a structured way to provide knowledge sharing, strengthening of defenses, coverage, and response, and ultimately the development of a high level of security maturity over time. This new concept of "Red + Yellow == Orange && Blue + Yellow == Green" focuses on the role of Developers as a critical piece of security assurance activities when combined with Security Teams. Orange Teams add value when they have been integrated into SDLC by creating a cycle of perpetual offensive testing and threat modeling to make software more secure over time through a high level of dedicated interaction. Green teams add value when they help ensure software is capable of providing powerful logging and DFIR information. This talk will evaluate the current gap in skills and knowledge, and explore how different Team combinations can lead to more secure software.

When the Sweet Turns Sour: Managing Your Open Source Risk

Presented by: Pete Chestna

No one builds software completely from scratch anymore. The use of open source software is at an all-time high. The benefits in terms of time to market are too great to ignore. Once incorporated, they are orphaned and left to fend for themselves. That’s a huge problem when a CVE is announced and we are left with a hugely expensive upgrade or uncontrolled exposure to risk. Let's talk strategy.

Know Your Tools: A Developer's Perspective on How to Reproduce/Remediate Top 10 OWASP Vulnerabilities

Presented by: Venkatesh Ganapathy

This presentation is based on my experience in different products with which I was involved. It includes considerations that every developer should take to secure the applications. As developers, our task to figure out and remediate OWASP Top 10 vulnerabilities is the top priority, but there is no one automated tool that can detect all security flaws listed in the OWASP Top 10. It is necessary to use a combination of different tools to make sure our application is free from any vulnerabilities. I am going to go through the OWASP Top 10 vulnerabilities list and recommend/demonstrate different tools to use to help reproduce and remediate each vulnerability.

A Top 10 List for Better AppSec (Hint: It's Not the OWASP Top 10)

Presented by: Dave Ferguson

By far the best known “list” in the arena of application security is the OWASP Top 10. There’s no question it has helped greatly over the years to raise awareness of common vulnerabilities in web applications like SQL injection, XSS, and CSRF. But in the end that’s all it is – an awareness document. This session will introduce and examine a different top ten list that is aimed at developers who are actually writing the code and building the software. It is known as the OWASP Top 10 Proactive Controls and it’s chock-full of practical, application security goodness. The audience will learn how secure development techniques and prescriptive guidance provided in the Top 10 Proactive Controls can move the needle toward having highly secure applications throughout an organization.

SDLC Automation; using Web Application Vulnerability Scanner APIs

Presented by: Jim Weiler

Continuous Integration!! DevSecOps!! SecDevOps!! Application security automation gets lots of buzz and products are evolving to accommodate it, says Gartner. I'll explain the simple setup and process we have using Qualys, Jenkins, java and Excel to automate the creation, rescan and reporting of web app vulnerability scans. I'll also compare the APIs of some commercial products. I'll describe the tasks you need to do before automation can happen and how we architected security and access control into our process.

Cleaning Up Messy Access Control Code by Writing Down the Rules

Presented by: Robert Thau

Many web applications have fairly complicated policies for determining who can access what data. A messy, but not uncommon, case is multi-tenant applications — say, a webapp with multiple client firms, different levels of access for particular users at each firm (perhaps in terms of which users have access to which projects or records within the app). Implementing all this access control with ad hoc logic can be tricky and error-prone. It can be hard to verify that different features are all applying the same rules. And once that’s done, augmenting it (say, to add a notion of “group” privileges within a tenant firm) can be fraught with peril.

An alternative is to explicitly represent the rules that the software ought to follow, in terms of who can access which elements of data, and what operations they can perform on them. Making this tangible, centralized data makes it possible to inspect, and easy to change, with assurance that new rules will be consistently followed.

This talk will describe the evolution of a system with a very complicated permissioning model over several years, describing benefits and pitfalls. It will also describe how much the application logic has to be driven by introspection on the rules — using them, for example, to build queries on which objects of particular types a user has permission to access or modify. In the end, the performance costs were modest, and the tradeoff with maintenance has made the exercise well worthwhile.

Only Handle It Once

Presented by: Chris Smith and Devin Dwyer

Keeping your applications safe can be a Sisyphean task. When an issue is found and fixed, how can you ensure the problem never resurfaces? This talk will walk through a real-world example of finding a major vulnerability, fixing it with an elegantly simple security control, and preventing it from coming back via a custom checkin-time code scan. How do we take care of a vulnerability? We Only Handle It Once.

Ex-Ray: Finding Browser Extensions That Spy on Your Browsing Habits

Presented by: Michael Weissbacher

Web browsers have become the predominant means for developing and deploying applications, and thus they often handle sensitive data such as social interactions or financial credentials and information. As a consequence, defensive measures such as TLS, the Same-Origin Policy (SOP), and Content Security Policy (CSP) are critical for ensuring that sensitive data remains in trusted hands. Browser extensions, while a useful mechanism for allowing third-party extensions of core browser functionality, pose a security risk in this regard since they have access to privileged browser APIs that are not necessarily restricted by the SOP or CSP. Because of this, they have become a major vector for introducing malicious code into the browser. Prior work has led to improved security models for isolating and sandboxing extensions, as well as techniques for identifying potentially malicious extensions. The area of privacy violating browser extensions has so far been covered by manual analysis and systems performing search on specific text on network traffic. However, comprehensive content-agnostic systems for identifying tracking behavior at the network level are an area that has not yet received significant attention.

In this talk, I will present a dynamic technique for identifying privacy-violating extensions in Web browsers that relies solely on observations of the network traffic patterns generated by browser extensions. Next I will present Ex-Ray, a prototype implementation of this technique for the Chrome Web browser, and use it to evaluate all extensions from the Chrome store with more than 1,000 installations (10,691 in total). Our evaluation finds new types of tracking behavior not covered by state of the art systems. Finally, I discuss potential browser improvements to prevent abuse by future user-tracking extensions.

This talk is about a paper accepted to ACSAC 2017.

Basic Web App Vulns Past SQLi and XSS

Presented by: Patrick Laverty

Great talk for beginners or people learning about web application vulnerabilities! At this point, most people are aware of SQL injection and Cross Site Scripting. We've seen how they work and seen how to mitigate them. Great. That's about all I have to say about those. Let's look at the additional web application vulnerabilities that may be getting overlooked. Let's look at other common vulnerabilities like Cross Site Request Forgery, Session Management, Clickjacking. We'll learn how to find them, exploit them and mitigate them.

Fingerprinting Healthcare Infrastructure for Fun and Profit

Presented by: Anirudh Duggal

Over the past year we have seen an increased use of open source intelligence for attacking institutions. The recent ransomware attacks have proven that healthcare institutions need more security and monitoring more than ever.

In my talk I will explain how to use deep web tools - shodan and censys effectively to track hospitals and healthcare institutions. I will share some of the interesting scenarios that I have seen and finally how to create scripts to automate this process. This includes optimizing the payloads and understanding how to narrow down to targets.

Wiping Out CSRF

Presented by: Joe Rozner

CSRF remains an elusive problem due to legacy code, legacy frameworks, and developers not understanding the problem or how to protect against it. Wiping out CSRF introduces primitives and strategies for building solutions to CSRF that can be bolted on to any http application where http requests and responses can be intercepted, inspected, and modified. Modern frameworks have done a great job at providing solutions to the CSRF problem that automatically integrate into the application and solve most of the conditions. However, many existing apps and new apps that don't take advantage of these frameworks or use them incorrectly are still plagued with this problem. Wiping out CSRF will provide an in depth overview of the various reasons that CSRF occurs and provide payload examples to target those specific issues and variations. We'll see live demos of these attacks and the protections against them. Next we'll look at how to compose these primitives into a complete solution capable of solving most cases of CSRF explaining the limits and how to layer them to address potential short comings. Finally we'll finish by looking at Same Site Cookies, a new extension to cookies that could be the final nail in the coffin, and see how to use the prior solution as a graceful degradation for user agents that don't support it yet.

Finding the Few and Far Between from Public Domain: A Systematic Approach

Presented by: Roshan Thomas

Reconnaissance is the first stage of a hacking process. During this stage, the attacker collects as much information as possible about the target from publicly available sources. Most common sources used are search engines, social networks & technical forums. It’s during this stage the attacker identifies low hanging fruits and the weak spots of the target. The information collected in the reconnaissance stage is used in further stages to tailor attacks against a particular weak spot of the organization.

In passive reconnaissance, the attacker tries to be as non-intrusive as possible to stay out of the target’s radar. Public domain data is the main source of information in this stage of an attack. The key motto of a passive reconnaissance is to identify the attack surface without triggering any alert. In this talk, I will be covering how a systematic approach in performing non-intrusive recon can help us find gems.
