We have a very active 2016 summer planned! June & August Chapter meetings and a Hackathon in the works for July. Stay tuned and be sure to spread the word!

If you're interested in speaking, sponsoring or hosting an event, please contact us.


Anyone in our area interested in application security is welcome to attend. Our meetings are informal and encourage open discussion of all aspects of application security. We invite attendees to give short presentations about specific topics.

Make sure you sign up for the mailing list to receive meeting announcements. Our mailing list is at:

6:00-6:30pm - Gather and mingle

6:30-7:15pm - Random Number Generation - Lava Lamps, Clouds and the IoT

Random numbers are the basis of security for all cryptography, yet they are often taken for granted. Learn why random numbers are so hard to generate and validate, compare different technologies in use today across virtualized environments, and discuss operational steps to take the risk out of random numbers and help secure cryptosystems even into the era of quantum computers.

Bio: Richard Moulds has more than 15 years experience in the security industry with a specific focus on cryptography. Richard has worked with customers in the areas of card and mobile payments, PKI, storage encryption, hardware security modules and enterprise key management. He has participated in OWASP, PCI DSS, OASIS, CSA and Quantum Safe industry groups and is the author of Key Management for Dummies.

7:15-7:35pm - Coffee Science w/ Intelligensia Coffee

Hackers and coffee go together like peanut butter and jelly, because as David Lynch once said, "Coffee has always seemed to facilitate thinking and catching ideas. Not only that, but the flavor of coffee is beyond the beyond good.” So do you want to know how to achieve the perfect cup of coffee? This talk will give you the lowdown on the science behind roasting, the chemical reactions that take place, the different varietals of beans and more.

7:45-8:30pm - What is Attribute-Based Access Control (ABAC) and how can I use it to secure APIs?

Abstract: Securing applications is more than just about identity. There have been many successful protocols and standards around authentication and federation (SAML, Open ID, OAuth, OIDC...). But they all tend to focus on users only - on the identity. Going beyond who the user is, we can start looking at what users want to do. This is where ABAC kicks. ABAC is a policy-driven way of defining fine-grained access control that can be reused across APIs, microservices, web applications, and data layers. Instead of hard-coding authorization into your application, externalize it using ABAC.

Bio: David Brossard works at Axiomatics and helps enterprise customers design authorization solutions that enable secure data sharing in compliance with compliance and privacy regulations. David's main area of expertise is SOA security. David has published several papers and contributed to several books on the topic of SOA security, governance, and attribute-based access control. David is also one the key figures in the OASIS eXtensible Access Control Markup Language (XACML) Technical Committee. In particular David has been driving standardization efforts around the developer experience on fine-grained, attribute-based access control.
