Securing Your Network Before BYOD or IoT

If you’re a network engineer or have been following some of the recent trends in network security space, you may have come across terms such as “erosion of trust”, “zero trust ecosystem”, “the increased attack surface” and “new attack vectors”. What this means for a network engineer is that as application migrate from on-prem to cloud, and trends like mobility and IoT vastly expand the scale of assets and forms of access to be secured, traditional network security, which historically was centered around securing the perimeter of your network, is no longer sufficient.

Anatomy of Data Breach

I was recently reading the Symantec Internet Security Report. This report has been quite appropriately themed as “2013: Year of the Mega-Breach”. In particular, the Point-of-Sale type of attack, mostly prevalent in the retail segment of the market, is a great indicator of the anatomy of a typical breach. So I’ll use that as an illustrative example for the purposes of this post.

Extended By Popular Demand: The Cisco IoT Security Grand Challenge

June 16, 2014 at 5:00 am PST

Since its announcement at the RSA 2014 conference, the security community has been actively involved in the Cisco IoT Security Grand Challenge, an industry-wide initiative to bring the best and brightest security minds to the table to help us find innovative IoT security solutions. Thus far, we’ve had dozens of wonderful submissions and they’re still coming in.

The initial deadline to make a submission was this coming Tuesday, June 17th. However, the challenge has been so popular that we’ve decided to extend the deadline by two more weeks, to July 1st, to give you an opportunity to complete your best work. After all, we all benefit by ensuring that the things we connect are secure. And with billions of objects networked all over the world, many of which will reside in insecure locations, security is arguably more important for IoT than it has been for any other technology in history.

Cisco will select up to six winners, each of whom will be awarded between $50,000 and $75,000 USD. The winners will be announced, and will have an opportunity to present their winning submission, at the IoT World Forum in Chicago, October 14-16, 2014!

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 »

Summary: IoT Holds Great Promise – But Ensuring Its Security Takes Strong Leadership and Teamwork!

April 18, 2014 at 7:20 am PST

Despite the many benefits of IoT, the billions of connected sensors, devices, and other smart objects it comprises will also dramatically increase the diversity of threats we will face. As a result, ensuring that we can reap the overwhelming benefits of IoT without undermining security will take strong leadership and a great deal of teamwork throughout the industry. That’s why I’m proud that Chris Young, Senior Vice President, Cisco Security Group, recently made the list as one of the top 100 thought leaders for IoT!
