Speaker Workshops Abstracts and Bios
Adding Ramparts to Your Bastille: An Introduction to SELinux Hardening
Jay Beale, CTO, COO at InGuardians, Inc.
Has your first action when acquiring a Red Hat system been to deactivate SELinux? In this fast-paced talk, you'll learn how to investigate and understand an SELinux-enabled system, and how to configure it. You'll learn how to build a policy for a new program and modify one for an existing. Finally, you'll learn about the boolean on-off switches built into the system that keep you from having to modify policies at all. If you want a speedy challenge, bring a CentOS 7 system with the packages listed on http://www.inguardians.com/selinux/ installed.

Attacks on Enterprise Social Media
Mike Raggo, Chief Research Scientist at ZeroFOX
Current threat vectors show targeted attacks on social media accounts owned by enterprises and their employees. Most organizations lack a defense-in-depth strategy to address the evolving social media threat landscape. The attacks are outside their network, commonly occur through their employee's personal accounts, and circumvent existing detection technologies. In this presentation we'll explore the taxonomy of social media impersonation attacks, phishing scams, information leakage, espionage, and more. We'll then provide a method to categorize these threats and develop a methodology to adapting existing incident response processes to encompass social media threats for your organization.

Automated Dorking for Fun and Profit^WSalary
Filip Reesalu, Security Researcher at Recorded Future
A dork is a specialized search engine query which reveals unintentional data leaks and vulnerable server configurations. In order to catalogue vulnerable hosts with minimal manual intervention we're now introducing an open-source framework for grabbing newly published dorks from various sources and continuously executing them in order to establish a database of exposed hosts. A similar project (SearchDiggity, closed source, Windows only) had its latest release in 2013 and the latest blog post was published in 2014.

Building a Local Passive DNS Tool for Threat Intelligence Research
Kathy Wang, Security Strategist and Researcher at Splunk, Inc.
Currently, many Security Operations capabilities struggle with obtaining useful passive DNS data post breach. Breaches are often detected months after the attack. Due to the ephemeral nature of malicious DNS domains, existing well-known passive DNS collections lack complete visibility to aid in conducting incident response and malware forensics. We will present a new tool to collect local passive DNS data, which will enable security operations capabilities to conduct more effective defense against malware, including APTs, zero days, and targeted attacks. Our presentation will consist of a demo of the tool, and the tool will be released for public use.
Kathy Wang (Twitter: @wangkathy) Kathy Wang is an internationally-recognized malware expert, who has researched, developed, evaluated, and operationalized various solutions for detecting and preventing client-side attacks used by advanced persistent threats (APT), as they target common platforms (e.g., browser, email, mobile phones).

Connections: Eisenhower and the Internet
Damon "Chef" Small, Technical Project Manager at NCC Group
"Rise of the Machines" conjures thoughts of the evolution of technology from the exclusive domain of computer scientists in the early days of our industry to including everyday people using - and often wearing - Internet-connected devices. With that theme in mind, the speaker researches the history of one large, government-funded infrastructure and compares it to another. Specifically, the Eisenhower Interstate System and the Internet. "Connections: Eisenhower and the Internet" explores what the logistical challenges of moving vehicles across the Country can teach us about cybersecurity. Although these two topics seem unrelated, the speaker will take the audience on a journey that begins with early 20th century road-building projects, travels through ARPANET and the commercialization of the Internet, and arrives at current-day cyberspace. These two massive infrastructures have changed the world, and there are important lessons that the former can teach about the latter. The presentation concludes with predictions about the future of the the Information Superhighway and how information security professionals can prepare.
Chef (Twitter: @damonsmall) earned his handle from his use of cooking metaphors to describe infosec concepts to laypeople.

Recent speaking engagements include DEFCON 23, BSides Austin, BSides San Antonio, HouSecCon, and ISSA Houston.
Crawling for APIs
Ryan Mitchell, Senior Software Engineer at HedgeServ
However, moving page logic client side can also create data vulnerabilities, as companies leave internal APIs exposed to the world, in order for their client side code to make use of them. I'll show some examples of this practice on traditionally "impossible to scrape" pages, and also some tools I've developed to crawl domains and discover and document these hidden APIs in an automated way. While many bot prevention measures focus on traditional page scraping and site manipulation, scripts that crawl sites through API calls, rather than in a "human like" way through URLs, may present unique security challenges that modern web development practices do not sufficiently address.

Deceive and Succeed: Measuring the Efficiency of a Deception Eco-System in Post-Breach Detection
Omer Zohar, Head of Research at TopSpin Security
Today's networks are undergoing all sorts of sinister attacks from numerous sources and for myriad reasons. Security at the perimeter is inadequate for thwarting today's highly intelligent attacks as hackers routinely breach the perimeter and gain entry. It isn't long before the network is compromised and critical information is stolen. We must now assume that, despite significant investments in prevention, breaches are going to happen. An additional approach is required. Security teams must go on the offensive, creating a web of non-stop, real-time detection operations using multiple vectors against an ever-changing landscape of cyber threats. Deception technology now plays a critical role. Used as a strategy for many centuries in actual warfare, the concept of deception is becoming a significant weapon in network-protection schemes. Deception technology doesn't rely on known attack patterns and monitoring. Instead, it employs very advanced luring techniques to entice attackers away from valuable company assets and into pre-set traps, thus revealing their presence. It is able to detect threats in real time without relying on any signatures, heuristics or complex behavioral patterns. But how effective is a deception strategy in detecting breaches? What method works best? How does it integrate with current security operations already in place?
In this talk we will present findings from a first ever research which measured the efficiency of proactive deception using mini-traps and decoys in real-life threat scenarios. We have reconstructed a real enterprise environment complete with endpoints, servers, network traffic and data repositories as well as security tools such as IDS, firewall, SIEM etc. The deception layer was then integrated into the environment in 2 steps: (a) by placing decoys in the network and (b) by placing mini-traps on the assets which point to the decoys, set false credentials, trigger silent alarms and more. We then evaluated the effectiveness of the mini-traps and decoys against both automated, machine-based attacks as well as against sophisticated human attacks: The first stage involved checking the behavior of a variety of malware families against the environment and measuring the deception layer's success in detecting their activity. For the second phase, we invited red-team professionals and white hat hackers to employ real techniques and advanced tools with the task of moving laterally in the environment and exfiltrate high value data.
Omer Zohar has over a decade of experience as a developer and researcher in the data security market. As head of Research for TopSpin Security he is responsible for the research of malware and post-breach detection methods and for defining advanced detection schemes.
Dynamic Population Discovery for Lateral Movement Detection (Using Machine Learning)
Rod Soto, Senior Security and Researcher at Splunk UBA
Joseph Zadeh, Senior Security Data Scientist at Splunk UBA
The focus of this presentation is to describe ways to automate the discovery of different asset classes and behavioral profiles within an enterprise network. We will describe data driven techniques to derive fingerprints for specific types of individual and subgroup behaviors. The goal of these methods is to add context to communications taking place within an enterprise as well as being able to identify when certain asset profiles change there behavioral fingerprint in such a way as to indicate compromise. The type of profiles we want to discover can be tied to human behavior (User Fingerprinting) or particular asset classes like WebServers or Databases (Hardware/Software Fingerprinting). Finally enriching these profiles with a small amount of network context lets us break down the behaviors across different parts of the network topology.
These techniques become important when we want to passively monitor for certain attacks against server hardware even without visibility into the local logs running on the server. For example we will cover the automated discovery and enrichment of DMZ assets and how we use these techniques to profile when a server has been planted with a Webshell or when an asset has been used to covertly exfil data. The methods we propose should be generic to apply to a wide variety of any kind of Layer 4/ Layer 7 traffic or just PCAP data alone.

Fuzzing For Humans: Real Fuzzing in the Real World
Fuzzing tools are frequently seen in big-name conferences, attached to big-name hacks and big-name hackers. Fuzzers are an incredibly useful offensive tool, and equally critical for a defensive player. But anyone who has tried to use these big-name fuzzers to secure their own software has seen how ineffective they can be. The fuzzing world is plagued with over-hyped and under-developed fuzzers that will suck the life out of anyone who dares try to sort through their waterlogged codebase. Meanwhile, commercial players stand by ready to support big businesses, but not open source. Commercial fuzzers may be good business, and their existence is a boon for the industry, but they are not sufficient for widespread security. They keep the power of fuzzing locked up for those willing to pay big bucks. And the closed source nature stamps out community, leaving each business to develop their own practices. In this talk, Joshua will provide a practical perspective on fuzzing, explore the hurdles confronting current open source tools and pave a path forward. Attendees will also receive an introduction to DIY fuzzers using modern frameworks.

HTTP/2 & QUIC - Teaching Good Protocols To Do Bad Things
Catherine (Kate) Pearce, Senior Security Consultant at Cisco Security Services
Vyrus, Senior Security Consultant at Cisco Security Services
The meteoric rise of SPDY, HTTP/2, and QUIC has gone largely unremarked upon by most of the security field. QUIC is an application-layer UDP-based protocol that multiplexes connections between endpoints at the application level, rather than the kernel level. HTTP/2 (H2) is a successor to SPDY, and multiplexes different HTTP streams within a single connection. More than 10% of the top 1 Million websites are already using some of these technologies, including much of the 10 highest traffic sites. Whether you multiplex out across connections with QUIC, or multiplex into fewer connections with HTTP/2, the world has changed. We have a strong sensation of Déjà vu with this work and our 2014 Black Hat USA MPTCP research. We find ourselves discussing a similar situation in new protocols with technology stacks evolving faster than ever before, and Network Security is largely unaware of the peril already upon it. This talk briefly introduces QUIC and HTTP/2, covers multiplexing attacks beyond MPTCP, discusses how you can use these techniques over QUIC and within HTTP/2, and discusses how to make sense of and defend against H2/QUIC traffic on your network. We will also demonstrate, and release, some tools with these techniques incorporated.

Incident Code Name: When SkyFalls A Shaken, Not Stirred, James Bond Tale on Incident Response
Plug, Security Operations and DFIR at Verizon Digital Media Services
The headlines shout the latest exploits of rogue actors and nation states. The hunters, cloaked in anonymity, strike without warning, devouring Intellectual Property and destroying corporate reputations. Potential victims cower in Fear, Uncertainty and Doubt, hoping they can hide in plain view. But can we learn from the hunters strategies to mount an effective defense? In this talk we'll take a look at events that took place on the James Bond film Skyfall. We will look at the film from the Incident Response point of view, and analyze the events and actions that took place in the film with comparisons of real life examples. Finally, we'll create a profile of the "evil" characters in the film along with James Bond and the team behind him at MI6. What team member would you be? Q, the weapons geek? Moneypenny, sidekick and junior field agent? M, the shrewd manager? Or James Bond, the tip of the spear, utilizing multiple strategies and tools to defeat his opponents.

Presenting Security Metrics to the Board / Leadership
The board of directors and corporate leadership is not interested in how many attacks your firewall has blocked, and frankly, that is not a metric, that is a measure. Difference between metrics and measurements, how metrics are constructed, and the kinds of metrics the board of directors are interested in will be discussed. In other words, how to identify how to align security metrics with business goals and objectives. The use of frameworks such as ISO 27004 to construct metrics, the pragmatic framework and its uses will also be discussed.

Verifying IPS Coverage Claims: Here's How
Garett Montgomery, Security Team Lead: Application and Threat Intelligence Research Center (ATIRC) at Ixia
IPS devices are now an accepted, integral part of a defense-in-depth InfoSec strategy; by strategically positioning them on the network, attacks can be blocked before they ever reach their intended targets. But with the explosion of public exploits, polymorphic malware and an ever-increasing attack surface, how can IPS devices keep up? They all seem to have heuristic detection capabilities, which are supposed to protect you from unknown exploits, and frequent updates to protect against known vulnerabilities. But just how effective are those defenses? Sure, you can check out the Gartner magic quadrant or pay for the latest NSS Test report. Just because an IPS claims to protect you from a vulnerability doesn'tmean thats the case. In this talk, I'll talk about some of the strengths and weakness of IPS devices, as well entire classes of exploits that cause serious problems for IPS devices. While I happen to work for a company sells a very expensive device for testing IPS devices (which is where the data and my opinions come from), I plan to focus on how the same testing methodologies can be applied and the results can be duplicated using open-source tools.
Garett Montgomery (Twitter: @garett_monty) is Security Team Lead at Ixia's ATI Research Center, where the primary focus is on simulating attacker behaviors in order to provide realistic test scenarios for network-based protection devices.

You Are Being Manipulated
GrayRaven, Senior Software Engineer at Cisco Systems
You are being manipulated. There is constant pressure coming from companies, people, and attackers. Millions are spent researching and studying your weaknesses. The attack vectors are subtle. Most times we don't realize that manipulation has occurred until it is too late. Fear not, we can harden our defenses. We can put safeguards in place to help avoid being the victim. For me, the answer came from an unlikely source: my daughter. Small children are fantastic. Society has not yet influenced their development; therefore, children are relentless in pursuing their aims. Since they are naive to right and wrong, they will use any tool available to get their goal. How does this help? My daughter became my trainer, and this talk discusses how interacting with her has improved my defenses. Comparing her strategies to real world examples will show how to build a training framework of your own. Access to small children is not needed.
GrayRaven (Twitter: @_grayraven_) is a senior software engineer at Cisco Systems. He has been fascinated with manipulation since his childhood. Despite receiving a degree in psychology, he spent 18 years as a professional in the Information Technology space. GrayRaven spent the first seven years of his career as a system and network administrator before moving to the dark art of programming. Two years ago he stopped dabbling and tumbled down the security rabbit hole. This journey makes him believe that he is finally using his degree professionally. During his downtime, GrayRaven can be found practicing martial arts, brewing beer and mead, or writing.
