jheary — Wed, 05 Dec 2007 12:29:21 -0500

Cisco has finally entering the high speed IPS market segment! Cisco’s is shipping the IPS 4270 IPS Appliance which can deliver up to 4Gbps of real-world media-rich traffic inspection. Cisco is proud of the fact that this benchmark number was achieved with the Cisco recommended IPS protection settings enabled on the 4270. They used real-world, stateful traffic flows in their testing. Cisco has not released the best case, pie in the sky, UDP performance numbers of the 4270 yet. But it has released expected real-world performance numbers if you deploy the 4270 in a highly transactional environment like e-commerce or IP Voice. This type of environment will drop performance down to 2Gbps of IPS inspection.

Cisco has doubled the speed of its intrusion-prevention sensor, the Cisco IPS 4270, boosting the rate at which it checks rich-media traffic.

According to a story by Network World's Tim Greene: Cisco uses a new rating system to describe the throughput of the device, giving it a speed for rich-media traffic and a separate rating for transactional traffic. IPS 4270 puts out 4Gbps for media-rich traffic and 2Gbps for highly transactional environments, the company says. It supports as many as 20,000 transactions per second. The ratings for the previous top-end IPS, the IPS 4260, is 2Gbps for media-rich and 1Gbps for transactional environments, the company says.

Cisco gives its Security Research Center a Makeover

Not many people realize that Cisco has been silently improving their security threat information site called The Cisco Security Center (www.cisco.com/security). I would also go out on a limb and guess that not many people ever knew Cisco provided free security research content. Bottom line is the site offers lots of excellent, and free, security content. A large percentage of the content comes from its IntelliShield business unit. Cisco IntelliShield is a paid, subscription service that provides all sorts of customized security reports. The good news is that many of the general reports are now being offered for free on the Security Center Website. So what cool reports are available on this site, well here are some examples:

Security Collaboration: Cisco IPS and Cisco Wireless

jheary — Wed, 26 Sep 2007 15:30:19 -0400

Not many people realize that the Cisco IPS 4200 Series sensors can collaborate with a Cisco Wireless LAN Controller(WLC) to defend the network. This solution allows you to extend your security protection way beyond what the embedded wireless signatures can offer. It moves your wireless attack detection/prevention capabilities from the solely Layer 2 realm, that embedded wireless signatures offer, into the Layer 2-7 realm. And since Layer 2-7 protection is arguably where you want/need to be this solution gets you there.
