As a follow up to my introductory blog on Securing the Internet of Everything, I would like to discuss further the security implications that will comprise proposed framework. As the applications of the IoT/M2M affect our daily lives, whether it is in the Industrial Control, Transportation, Smartgrid or Healthcare, it becomes imperative to ensure a secure IoT/M2M system. As the use of IP networks are employed, IoT/M2M applications have already become a target for attacks that will continue to grow in both quantity and sophistication. Both the scale and context of the IoT/M2M make it a compelling target for those who would do harm to companies, organizations, nations, and people.
The targets are abundant and cover many different industry segments. The potential impact spans from minor irritant to grave and significant damage and loss of life. The threats in this environment can be similarly categorized as those in the traditional IT environments. It’s useful to consider general platform architecture when discussing IoT security challenges. Below is the platform architecture that uses to frame IoT/M2M discussions.
While many existing security technologies and solutions can be leveraged across this architecture, perhaps especially across the Core and Data Center Cloud layers, there are unique challenges for the IoT. The nature of the endpoints and the sheer scale of aggregation in the data center require special attention.
The architecture is composed of four similar layers to those described in general network architectures. The first layer of the IoT/M2M architecture is comprised of Read More »

Hello, and welcome to my blog. As a new member of the Enterprise Networking’s Solutions Marketing team, I’ll be writing about connectivity to the cloud, Software Defined Networking (SDN) and virtualized routing. You can expect to learn details around Cisco’s architecture and product offerings in these topics. Further, based on your comments, I can go into as much detail as necessary.
First, a brief background. I moved to the Bay Area last November from Boston after almost 20 years in New England (in Boston), so I will be musing about culture shocks between the two coasts. I may also learn to like the Warriors and Niners, but I will always be a Celtics and Patriots fan. Read More »

Segment routing (SR) is a concept that’s been working its way through the IETF standards process but is finally becoming ready for real world deployment. It’s a network technology that provides enhanced packet forwarding behavior while minimizing the need for maintaining awareness of mass volumes of network state. SR satisfies essential requirements for application-enabled routing in software defined networks, including the ability to provide strict network performance guarantees, efficient use of network resources and very high scalability for application-based transactions. Segment Routing relies on a small number of extensions to IS-IS and OSPF and can operate with an MPLS or an IPv6 data plane and integrates with the rich multi-service capabilities of MPLS such as L3VPN, VPWS, VPLS, E-VPN, etc.

SDN has become a popular topic – so much so that this year’s MPLS/Carrier Ethernet/IPv6 World Congress in Paris added an SDN Summit component. It’s an area of high interest for Cisco as we develop our Open Network Environment, a portfolio of Cisco technologies and open standards which brings programmatic control and application awareness to the network, combining the benefits of hardware and software across physical and virtual domains.

Based on the online dialog on Easy Virtual Network (EVN) that I’ve seen, it appears that some people still have questions. We thought our story was as simple to understand as EVN is to use, but there is a need for clarification. Here’s a bit more information about what EVN is and what it isn’t.
One online comment was, “It’s a Cisco proprietary version of MPLS for the enterprise.” No, we believe in MPLS. It’s supported on a number of Cisco platforms and is used by many of our customers. MPLS is the most scalable and perhaps the most capable means of network virtualization. But it’s also overkill and far too complicated for many enterprises.
