Sourcefire readies virtual intrusion prevention appliances

Sourcefire 3D System 4.9 to receive Virtual 3D Sensor and Virtual Defense Center

Sourcefire is readying its first intrusion-prevention systems designed to run as software appliances in VMware's virtual machine environment.

Sourcefire 3D System 4.9, which is expected to ship by year-end, includes the Virtual 3D Sensor and the Virtual Defense Center. The products will run as virtual appliances on VMware's ESX and ESXi servers, as well as on the cloud-computing platform vSphere 4.0.

Sourcefire 3D System 4.9, now in beta, can be used to inspect traffic between two physical hosts, two VMs or between a physical host and a VM, according to Steve Piper, Sourcefire's senior director product marketing.

The first virtual IPS appliances that Sourcefire will ship will deliver speeds ranging from 20M to 250Mbps. This is "the low end" for IPS speeds today, Piper acknowledges.  

Piper says there are some basic concerns regarding a virtual appliance -- which is simply software tailored to run in a specific VM environment -- as compared with a physical appliance that includes software on a dedicated hardware device.

"There are a lot of unknowns," Piper says, because the virtual appliance is likely to share a physical server with other VM applications and there may be wide differences in deployment and usage of resources.

The main concern is the performance of an IPS sensor running as a virtual appliance, he says. As the Sourcefire virtual appliances become available, "we encourage customers to test for performance," Piper says.

In its first iteration of virtual appliances, Sourcefire is not implementing VMware's VMsafe security API, because it's "not ready for prime time" due to performance issues related to Sourcefire's projects, Piper says.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
