Success with Cisco Application Visibility and Control

July 22, 2013 at 5:00 am PST

In December 2012, we introduced Application Visibility Control(AVC) for Wireless, with AireOS 7.4 which arms IT administrators with visibility into the applications running in their wireless network and the ability to prioritize the mission-critical ones.

In this blog, I would like to share how SuccessEHS, an Alabama based company focused on delivering Electronic Health Record(EHR) and Practice Management solutions has successfully deployed AVC to improve their wireless experience. I’ll also throw in a special sneak peek at some additional features we’re adding to AVC that you can expect in release 7.5.

SuccessEHS houses some 200-300 employees in Birmingham Alabama. The wireless deployment consisted of Cisco Aironet 2600 series Access Points with industry-leading 3 spatial streams performance and CleanAir functionality managed by the Cisco 2500 Series Wireless Controller. At any point of time, there could be hundreds of clients simultaneously connected to the wireless network. Most employees may be simultaneously engaged in running usual office applications such as email, web-based tools and EHR applications. Read More »

Higher Education Races Towards 802.11ac

[Webinar] 802.11ac in Higher Education | Wednesday July 24 at 3pm PST < REGISTER

It’s no secret that mobile devices are playing a larger part in today’s businesses. With the fast pace of mobility adoption by consumers, network usage has started to outrun the infrastructure of most enterprises’ mobile networks. Enterprise IT managers are struggling to keep up with mobility’s effects on workplace productivity and requirements.

Among the growing trends that weigh heavily on the minds of most network IT professionals is bring your own device (BYOD). The growth of bandwidth-intensive applications, like video streaming, and the user expectations of always-on network and application performance also place heavy demand on organizational infrastructure.

802.11ac is the next generation of Wi-Fi, designed to give enterprises the tools to meet the demands of BYOD, high-bandwidth applications, and the always-on connected user. This Wednesday we will be hosting a workshop to discuss the benefits of 802.11ac, and how to optimize it for high density and high bandwidth to benefit higher education. Students, typically early adopters of wireless technology, usually bring 802.11ac in the form of the latest laptop, smartphone, and tablet that support this new technology. Read More »

Invade the NOC: Video Tour & Weekly Recap for Enterprise Networks

If you’ve been to a CiscoLive recently, you’ve likley seen the beautiful plexiglass NOC we set up.  These are wonderful to show off how all of our products and services come together to put on the show and conference you know and love.  However, have you, ever seen those little hidden rooms sprinkeld throughout the show?

These little rooms are where we hide the mini-NOC.  In these the tables are fold-up and the cables hang out, and I got to get a tour and interview with the crew.

Cisco UCS Outperforms HP and IBM Blade Servers on East-West Latency

Virtualization, Private Cloud, Big Data, HPC, etc. have been steadily changing the landscape of data center architectures. Lower latency and higher performing server-to-server data traffic (East-West) have become key discussion points as customers look to modernize their infrastructures.  Cisco specifically designed UCS unified fabric for this type of traffic to create a highly-available infrastructure with reduced latency and unmatched consistency as the solution scales. Without providing any supporting data, HP and IBM have been incorrectly asserting that Cisco UCS unified fabric would increase latency and slow blade-to-blade traffic. Cisco ran the tests, and the results were simply amazing.

Zeus Botnet Impersonating Trusteer Rapport Update

July 19, 2013 at 12:50 pm PST

Starting Friday, July 19, 2013 at 14:45 GMT, Cisco TRAC spotted a new spam campaign likely propagated by the Zeus botnet. The initial burst of spam was very short in duration and it’s possible this was intended to help hide the campaign, since it appears to be targeted towards users of a Trusteer product called Rapport. Within minutes of the campaign starting, we were seeing millions of messages.

spam3

This spam impersonated a security update from Trusteer. Attached to this file was the “RaportUpdate” file, which contained a trojan. We’ve identified this specific trojan as Fareit. This file is designed to impersonate an update to the legitimate Rapport product, which, as described by Trusteer, “Protects end users against Man-in-the-Browser malware and phishing attacks. By preventing attacks, such as Man-in-the-Browser and Man-in-the-Middle, Trusteer Rapport secures credentials and personal information and stops online fraud and account takeover.”

It’s important to note that while this end-point solution is designed to protect against browser-based threats, this specific attack is email-based. If the user downloads and executes the attachment via their mail client, it could bypass their browser and the protections of a legitimate Rapport client, entirely. If an end user is tricked into running malicious software for an attack via an avenue the attacker can reasonably predict, it becomes much easier to bypass network security devices and software.
