When I was in grade school, my best friend had a favorite saying whenever he disagreed with somebody’s observation that two things were really similar. “It’s the same, only different,” he would quip. Though this phrase was mostly intended to be flippant and evoke an emotional response from the recipient, I’ve finally found a topic where his phrase is 100 percent legitimate; IoT security. That’s because when it comes to securing IoT, we’re not talking about a single, homogeneous network, but rather the extended network which comprises both Information Technology (IT) and Operational Technology (OT) environments.
While existing IT networks have included cloud and perimeter security for many years, OT environments have traditionally been air gapped from the Internet, and therefore only required physical security components to ensure a high level of secure access and safety for plant personnel. And since IT and OT networks were completely separate, the radical differences in their approach to security didn’t make much of a difference – users of each simply lived in blissful isolation. But IoT is changing all of that! Read More »

Cisco Live, May 18-24, 2014, is quickly approaching and registration is open. This is the 25th anniversary of Cisco Live and we return to the Bay Area at San Francisco’s Moscone Center. Educational sessions are organized into technology tracks to make it easy to find the topics that most interest you. With network and data security being top of mind, I’d like to highlight the Security technology track’s exciting content lineup. Read More »

May is fast approaching. Many people at Cisco, myself included, are making a lot of preparations for Cisco Live US which is May 18 -- 22, 2014 in San Francisco. This is a special year when Cisco Live returns to San Francisco. You might be wondering what’s special, and here’s a quick tip. It happens only every five years, when it’s a major Cisco anniversary year. Last time it happened, it was 2009 when Cisco celebrated its 25th anniversary. Over 10,000 people attended Cisco Live US that year. This year is Cisco’s 30th anniversary. The attendance is expected to be more than doubled. Here’re a few reasons that explain the rapid growth, based on 2013 the Cisco Live surveyed attendee feedback:
- 99% believe that Cisco Live was a good investment of their time
- 98% advised they gained valuable knowledge at the event that can be implemented by their company
Every year, new content and topics are being added so that you can keep up with technology evolutions and progress. I want to bring your attention to an exciting new hands-on, instructor-led training session: LTRCRS-2004 Catalyst Virtual Switching System -- Instant Access (VSS -- IA) Lab. It was first offered at Cisco Live Milan in January this year. It was a full house event – many people were put on the wait list because they did not register early enough. Read More »

For a few of us in the Cisco Brussels office the last weekend of January always marks a special occasion.
The weekend is dedicated to the Free and Open-source Software Developers’ European Meeting (FOSDEM) conference in Brussels, with around 5,000 visitors attending. The event happens at the ULB (Université libre de Bruxelles) campus, but traditionally uses its own network infrastructure, sponsored by Cisco. And we, who are Cisco employees, volunteered our time to help the community as well as meet some new friends and get extra hands-on experience with a sizable network.
What was different this year was that just before the official start of the conference I finally figured out how NAT64 works, gave a 5 minute warning on twitter (image below), and then disabled IPv4 on the main network (simply stated I removed the IPv4 address of the router on the client interface so that only the IPv6 address remained).
That meant that visitors would only get an IPv6 address Read More »

If you were unable to attend Cisco Live! Milan, or weren’t able to attend all the sessions that interested you, Cisco has made the session videos and PDFs available on the Cisco Live! website. More videos are being added daily and all should be available by February 22, 2014.
The Cisco Live! website maintains a large on-demand library with presentations and video recordings from Cisco Live! events hosted from 2011 to present. After registering, anyone can view the presentations and embedded videos at their leisure. Your Cisco Live! account is not tied to your Cisco.com account, so those credentials will not work!
Exciting new announcements are made regularly at Cisco Live! In Milan, Chris Young, Senior Vice President of Cisco Security, took the opportunity to share that Cisco was opening up it’s TrustSec capabilities to other vendors. In his blog post, Kevin Regan highlights what this means to the community. Read More »
