The Extended Network Requires Security That’s the Same, Only Different

April 23, 2014 at 6:00 am PST

IoT Double Edged SwordWhen 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 »

Catalyst Virtual Switching System and Instant Access (VSS – IA) Lab at Cisco Live US

March 31, 2014 at 6:00 am PST

CLUS14May 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 »

FOSDEM 2014: Cisco Powered World First

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 »
