Abstract: 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.
