AppSec Evolved: Continuous Security and Pipelines

Abstract: The security community has been slow to follow the lead of software developers and their adoption of process automation. What can we as security professionals glean from the Agile, Lean, DevOps and CI/CD methods implemented by these industry unicorns? This presentation will show how to catch up by providing examples of security being successfully adapted to these models. First, we will demonstrate how to configure an automated test harness from traditional manual testing. No need to re-test. Automation has you covered. Next, we’ll take two different companies’ experiences with running AppSec groups, Rackspace / Pearson, and later incorporate the concept of a build pipeline. Finally, we will show what can be done when these procedures are combined with actual year over year results that include 24/7 remediation advice, automated report generation, ChatOps and more. Learn how an Appsec Pipeline can keep your AppSec live productive and sane.

Application Event Logging

One of the most important sources of information for security threat detection and investigation is often the most neglected in the application development process. We're talking about application event logging - it isn't often sexy or interesting, but it could be the key to detecting an attack or compromise, or may provide the ability to successfully investigate unauthorized activities or operational issues.

If it is so important, then why are application developers not building an event logging framework into every application? And, why are the events that are being logged from many applications useless for security purposes or difficult to consume?

In this session we'll aim to answer these questions:

- Why are developers not implementing application logging capabilities?
- What mistakes are being made in the events that are logged?
- What should be logged?
- In what format should events be logged?
- What is the difference between security events and operational events? And, should we care about both?

Chris McGinley, CISSP, CCE Chris is a Managing Partner at BTB Security based out of Bala Cynwyd, PA. Chris has been practicing the information security profession for over 10 years and has been in and around the world of IT for nearly 25 years.

Static Analysis Programs – Current State and Future Direction Static analysis has grown in demand over the past decade and is now seen as one of the key practices in many software security initiatives across different industry verticals. When people think of static analysis, they immediately think of tools and automated solutions.

While there are several well-known tool vendors in the marketplace, there is not enough knowledge and experience in successfully implementing such technology in real-world organizations. Successful static analysis program implementation does not come without challenges and involves a progressive time-consuming journey. Effective program implementation should strategically account for people, process, and technology.

This presentation provides a holistic view of how the industry has taken its shape over the past decade, and what organizations need to know when planning for a new static analysis initiative.

Mr. Aravind Venkataraman is the Director of Cigital’s Static Analysis practice. He has over 8 years of experience in software security and network security. At Cigital (, he has spent the past 6 years helping a number of Fortune 100 companies build and run software security practices. He has performed planning, advisory and operational roles in building such practices. He specializes in deploying static analysis programs. He has helped several organizations deploy and run static analysis capabilities of different sizes and shapes. He presently plays a technical leadership and program advisory role both for internal staff and clients based out of Washington DC.

It's 10pm, Do You Know Where Your Access Keys Are?

We know that a large number of organizations are using AWS or are planning to. We also know that hackers are targeting organization’s AWS infrastructure. What you may not know, is how hackers are doing this and what you can do about it.

Join us as Ken Johnson, CTO of nVisium, discusses harnessing existing AWS functionality to strengthen your organization’s AWS infrastructure against practical attacks. Ken will show you what attackers are looking for, how they are finding you, how to secure your environment, and how to answer the question “Our access keys have been stolen, what do we do now?”.

Ken leads nVisium's product development efforts and is responsible for the security of engineering infrastructure and code. Ken co-built the Railsgoat project, an open-source security-centric training platform for Ruby on Rails developers, and is a frequent speaker on both security and development topics - DevOpsDays DC, LASCON, AppSec Cali, OWASP DC, RubyNation.

Title: IoT Beyond the Hype
Presenter: Justin C. Klein Keane is the security architect for ThingWorx (, a PTC business, that makes IoT development framework software. Justin has over 15 years of experience in the security field and is a major contributor to the OWASP IoT Project (, a member of the Build it Securely group (, the Securing Smart Cities project (, and an official contributor to the Online Trust Alliance feedback to the Federal Trade Commission's proposed guidelines on IoT security and privacy (

Abstract: IoT security is one of the most exciting new fields in the industry, but few understand its scope beyond hacking your connected toaster. Hospitals, industry, and agriculture are all leveraging IoT to realize value from big data, predictive analytics, remote management, and cloud connectivity. IoT is more than just the next evolution from desktop to web to mobile to cloud. IoT presents very real, and new, challenges, including machine to machine (M2M) trust, transitive ownership, and more. The OWASP IoT Project seeks to define this new problem space, enumerate common vulnerabilities, and propose methodologies for secure development. This talk will provide an overview of the OWASP IoT Project and movement in the problem space that goes well beyond hacking cars and baby monitors.

Title: Getting out of the Comfort Zone
Presenter: Aaron Weaver, Associate Director - Application Security, Protiviti

Abstract: In the last few years the development and operation practices have changed significantly in many organizations. Many organizations are embracing DevOps and what started out as an idea a few years ago with startups and large cloud companies is now being adopted by banks and traditional retailers. We in the security community need to be part of this change or we will be ignored or bypassed. It's time for security to look for news ways to enable change in a secure manner while still allowing the business to move at the speed they require.

Topic: Building an AppSec Pipeline
Presenter: Aaron Weaver


Are you currently running an AppSec program? AppSec programs fall into a odd middle ground; highly technical interactions with the dev and ops teams yet a practical business focus is required as you go up the org chart. How can you keep your far too small team efficient while making sure you meet the needs of the business all while making sure you're catching vulnerabilities as early and often as possible?

This talk will discuss a real world case study of an AppSec Pipeline. The pipeline starts with "Bag of Holding", an open source web application which helps automate and streamline the activities of your AppSec team. At the end of the pipeline is ThreadFix to manage all the findings from all the sources. Finally we incorporated a chatbot to tie all the information into one place. This talk will cover the motivation behind an AppSec pipeline, its implementation and how it can help you get the most out of your AppSec program.

Topic: Back to Basics: Application Assessment 101 - Pen Test Using Proxy Tool (Burp Suite Pro/ZAP)
Presenter: John Baek


We will drill down one aspect of web application assessment: web app penetration test. We'll discuss a popular tool for performing web app pen test and what the tester needs to understand to make it a successful/useful assessment.

Topic: Securing The Android Apps On Your Wrist and Face
Presenter: Jack Mannino


Android Wear introduces new ways of interacting with our apps and receiving timely, contextual information from the world around us. Smartphones and tablets are becoming the central point for sending and receiving data from wearables and sensors. Building apps for a wearable world introduces new risks as well as shifts the responsibilities for implementing security controls to other layers.

Many of the same issues we’re familiar with from past Android experiences are still relevant, while some issues are less impactful or not (currently) possible within existing wearables. At the same time, extending the app’s trust boundaries introduces new points of exposure for developers to be aware of in order to proactively defend against attacks. We want to highlight these areas, which developers may not be aware of when adding a wearable component to an existing app.

In this presentation, we will explore how Android Wear works underneath the hood. We will examine its methods of communication, data replication, and persistence options. We will examine how these applications into the Android development ecosystem and the new risks to privacy and security that need to be considered. Our goal isn’t to deter developers from building wearable apps, but to enable them to make strong security decisions throughout development.


Jack Mannino is the CEO at nVisium and loves solving problems in the field of application security. With experience building, breaking, and securing software, he founded nVisium to invent new and more efficient ways of protecting software. Jack is a huge fan of contributing to open source projects, and leads the OWASP Northern Virginia chapter. In his spare time, he loves to kick around new frameworks and technologies, especially things that run Android and code written in Scala. He’s also an optimistic New York Mets fan, although that optimism slowly fades away every summer.

Topic: HTML5 Security
Presenter: Justin C. Klein Keane or others


HTML 5 Security

While HTML 5 is a wonderful tool for developer, the new features also present some new security challenges. Security in HTML 5 is a widely varied topic and we may not yet understand all of the security challenges it will bring. HTML 5 poses a major paradigm shift in the way that web applications are delivered and consumed and time will tell whether this will result in a net positive or negative for security. The new anti-XSS mitigation features of HTML 5 are amazing, and well worth investigating if you're looking to develop a new application.

HECTOR, our evolving security intelligence platform
Presenter: Justin Klein Keane


Asset management is an ever present challenge for any IT organization, and especially so for information security groups. Even more challenging is data aggregation for intelligent security analysis (or security intelligence). HECTOR is an effort by the University of Pennsylvania's School of Arts and Sciences to provide such a security intelligence platform. Organizing assets, scanning for vulnerabilities and profiles, correlating attacks on your network to services offered by hosts, tracking changes, following remediation, and making information available to multiple users via a web interface are all goals of HECTOR. HECTOR leverages honeypot technology, darknet sensors, port scans, vulnerability scans, intrusion detection systems, the powerful open source MySQL database, and a PHP based web front end to provide security intelligence to security practitioners.

HECTOR is an evolving, open source effort that attempts to leverage a wide variety of tools and information sources to empower security practitioners with better insights as well as to track and trend security related data. Come hear about HECTOR in advance the official open source launch at the Educause Security Professionals 2012 conference. Presentation material will include a discussion of the philosophy behind HECTOR, the open source technologies that make HECTOR work, as well as design challenges and solutions. Even if you don't end up using HECTOR the presentation seeks to spur new ideas and ways of thinking about asset management and security data.

The Search for Intelligent Life

Synopsis: For years organizations have been mining and culling data warehouses to measure every layer of their business right down to the clickstream information of their web sites. These business intelligence tools have helped organizations identify points of poor product performance, highlighting areas of current and potential future demand, key performance indicators, etc. In the information security field we still tend to look at our information in silos. Dedicated engineers solely focused on web application security, network security, compliance and so on, all while bemoaning a lack of information and decision support.

In this talk, Ed will cover some of the many sources of security data publicly available and how to apply them to add context to your security data and tools to help make more intelligent decisions. Ed also points out a number of ways to repurpose information and tools your company is already using in order to glean a clearer view into your security and the threats that may effect it.

Bio: Ed Bellis is the CEO of HoneyApps Inc, a vulnerability management Software as a Service that centralizes, correlates, prioritizes and automates the entire stack of security vulnerabilities and remediation workflow. Prior to HoneyApps, Ed served as the Chief Information Security Officer for Orbitz, the well known online travel agency where he built and led the information security program and personnel for over 6 years. Ed has over 18 years experience in information security and technology. He is a frequent speaker at information security events across North America and Europe.

Mobile App Security Techniques

Look left, look right, look in your pocket, you probably glanced over a cellular phone. These devices are getting more and more pervasive in today's society. More importantly they are getting very powerful. This new market of software users have been the catalyst of the "app" boom. Everyone is jumping on board and developing mobile applications. This influx of mobile application development means there are a large number of mobile applications that get rushed to the market before they can be properly reviewed from a security standpoint. So guess what, more bugs for the taking!

In this talk we will lay out a few basic techniques that we use when we perform mobile application assessments, highlight possible pit falls that one should be aware and hopefully give those up and coming mobile application penetration testers a leg up on the competition.

Raj Umadas is a Consultant with the Intrepidus Group. Mr. Umadas graduated Summa Cum-Laude from The Polytechnic Institute of NYU with a BS in Computer Engineering. At NYU:Poly, Mr. Umadas pursued a highly expansive computer security curriculum. He is just as comfortable sniffing out a memory corruption bug as he is assessing the risk management decisions of large projects.

Coupled with Mr. Umadas' fresh academic outlook on security, he obtained a no-nonsense business sense of security while working in an Information Risk Management arm of a large investment bank. Corporate governance, segregation of duties, and SOX compliance were all daily concerns for Mr. Umadas.

Mr. Umadas is eager to establish his own niche in the security world where he will be the catalyst of some very major innovation. With his strong academics, proven real world experience, and never-say-no attitude; it is only a matter of time.

User Interface and Security in Web Applications

Security is often seen as a competing priority to good user experience, but the two are not diametrically opposed. Good user experience is essential to good security. Without ease of use, most people simply ignore or bypass security protections in systems. In order to craft effective security measures it is essential to take user experience into consideration. With the meteoric growth of web applications as a medium for service delivery it is critical to deploy good security measures. Web applications offer an always on, globally available target for attackers. Users need to be allies in the drive for application security, but far too often security measures are presented as onerous, time consuming, bothersome add-on's to web applications rather than seamlessly integrated, easy to use, user friendly features. In this talk I propose to explore some of the reasons why good security in web applications matters and how you can make security effective by making it easy to use.

Discovering PHP Vulnerabilities Via Code Auditing

Abstract: PHP provides an accessible, easy to use platform for developing dynamic web applications. As the number of web based applications grow, so too does the threat from external attackers. The open and global nature of the web means that web applications are exposed to attack from around the world around the clock. Automated web application vulnerability scanning technology is still very much in its infancy, and unable to identify complex vulnerabilities that could lead to complete server compromise. While intrusion detection systems prove very valuable in detecting attacks, the best way to prevent vulnerabilities is to engage in active code review. There are many advantages of direct code review over automated testing, from the ability to identify complex edge scenario vulnerabilities to finding non-exploitable flaws and fixing them proactively. Many vulnerabilities in PHP based web applications are introduced with common misuse of the language or misunderstanding of how functions can be safely utilized. By understanding the common ways in which vulnerabilities are introduced into PHP code it becomes easy to quickly and accurately review PHP code and identify problems. In addition to common problems, PHP includes some obscure functionality that can lead developers to unwittingly introduce vulnerabilities into their applications. By understanding the security implications of some common PHP functions, code reviewers can pinpoint the use of such functions in code and inspect them to ensure safety.
