Time: 7:30 Location: We will be meeting in the Anteater Instruction and Research Building on the UC Irvine campus. The building itself is inside of the Anteater Parking Structure at the corner of E. Peltason Dr and Anteater Dr and is room number 1020. Parking is $7 but feel free to park off campus and walk to the building. Buliding #653 in quadrant H9 on the campus map -

For those who would like to avoid paying for parking, you can park in the University Center and take the campus shuttle:

The shuttle runs until 10:45PM. The shuttle costs $1 per ride, but fees are rarely collected ;)

Title: Do VLANs allow for good application security?

Virtual Local Area Networks (VLANs) are not a new concept, and can help any organization better control network access. I will present some of the previous issues identified, what was the root cause, and how these have been fixed in current technology. In addition we will talk about how this can help to enhance security in your environment, and what controls must be in place in order to implement such an environment. We will also touch on how this can complicate your application environment, but improve overall security.

I will touch on the controls that need to be reviewed and audited when working with VMware, VLANs, and web applications, to ensure that these networks are secure, and what to look for to potentially pass audit criteria. I will also talk about where and how these controls have been implemented in order to protect thousands of users while accessing one of the most hostile networks in the world.

Title: Pulling the Plug: Security Risks in the Next Generation of Offline Web Applications

As the line between desktop and web applications becomes increasingly blurry in a web 2.0 world, browser functionality is being pushed well beyond what it was originally intended for. Persistent client side storage has become a requirement for web applications if they are to be available both online and off. This need is being filled by a variety of technologies such as Gears (formerly Google Gears) and the Database Storage functionality included in the emerging HTML 5 specification. While all such technologies offer great promise, it is clear that the vast majority of developers simply do not understand their security implications.

Researching a variety of currently deployed implementations of these technologies has revealed a broad scope of vulnerabilities with frightening implications. Now attackers can target victims not just once, but every time they visit a site as the victim now carries and stores the attack with them. Imagine a scenario whereby updated confidential information is forwarded to an attacker every time a victim interacts with a given we application. The attacker no longer needs to worry about timing their attacks to ensure that the victim is authenticated as the victim attacks himself! Limited storage? Cookies that expire? Not a problem when entire databases are accessible with virtually unlimited storage and an infinite lifespan. Think these attacks are theoretical? Think again. In this talk we dive into these technologies and break down the risk posed by them when not properly understood. We will then detail a variety of real-world vulnerabilities that have been uncovered, including a new class of cross-site scripting and client-side SQL injection.

Separate meetings will be held for OWASP OC and OWASP@UCI (student group).

When: Wednesday 10/14 7:30PM Where: Steelhead Brewery Topics: News, Ideas, Chit-chat

This is a restaurant/bar with plenty of seating, but room for a projector is out of the question so this would be an informal round table discussion.

I have a presentation I'm working on regarding WAFs and Vulnerability Assessment Tools. If it pleases the group, I'd love to go over the presentation and discuss everyone's experiences. Also, it's a great way to get feedback :)


I'm open to suggestions of any kind: location, time, topics, etc
