With a rapidly increasing number of people, devices, machines and sensors coming online across the Internet of Everything (IoE), global service providers will require new capabilities to lead in the delivery of value-added, cloud-based services and applications. Service providers are recognizing the importance of using intelligent, virtualized networks that efficiently deliver new experiences and expand revenue opportunities. While there are many residential, business and mobile solutions that service providers can offer, network virtualization is also crucial for deployment in developing regions.
The IoE aims to bring the world together through technology and empower those who were once isolated, by transforming the ways they communicate. Access to mobile technology varies and may not be as prevalent in developing regions of the world. However, tablets and mobile phones are beginning to transform how these developing regions obtain and relay information. In fact, mobile phone subscriptions have climbed to nearly 5 billion in the Read More »

Our service provider customers like you are trying to simultaneously keep pace with the surging network traffic in today’s Internet of Things (IoT) era while providing consistently high quality of experience and introduce new services quickly for a competitive advantage.
New technologies like Voice over LTE and the need to connect the expected 37 billion devices like cars, trains, building sensors, and “wearable devices” by 2020 means that data must be treated differently than it has been historically. At the same time, your consumers are expecting the same quality of experience whether they connect to th Read More »

The Internet of Everything (IoE) describes machine-to-machine (M2M) compute entities that track and measure real-time data that can be used to build out a data history for analytics that could be used to optimize the quality of life. The opportunity is represented by devices used in a person’s everyday life that are connected to the Internet, have the ability to learn a person’s consumption behavior, and embody the goal to improve the efficacy of services and goods delivery and consumption. Cisco Systems CEO John Chambers says that the Internet of Everything could be a $19 trillion opportunity. 1 Read More »

The HAVEX worm is making the rounds again. As Cisco first reported back in September 2013, HAVEX specifically targets supervisory control and data acquisition (SCADA), industrial control system (ICS), and other operational technology (OT) environments. In the case of HAVEX, the energy industry, and specifically power plants based in Europe, seems to be the primary target. See Cisco’s security blog post for technical details on this latest variant.
When I discuss security with those managing SCADA, ICS and other OT environments, I almost always get the feedback that cybersecurity isn’t required, because their systems are physically separated from the open Internet. This practice, referred to in ICS circles as the “airgap”, is the way ICS networks have been protected since the beginning of time; and truth be told, it’s been tremendously effective for decades. The problem is, the reality of the airgap began to disappear several years ago, and today is really just a myth.
Today, networks of all types are more connected than ever before. Gone are the days where only information technology (IT) networks are connected, completely separated from OT networks. OT networks are no longer islands unto themselves, cut off from the outside world. Technology trends such as the Internet of Things (IoT) have changed all of that. To gain business efficiencies and streamline operations, today’s manufacturing plants, field area networks, and other OT environments are connected to the outside world via wired and wireless communications – in multiple places throughout the system! As a result, these industrial environments are every bit as open to hackers and other cyber threats as their IT counterparts. The main difference, of course, is that most organizations have relatively weak cybersecurity controls in these environments because of the continued belief that an airgap segregates them from the outside world, thereby insulating them from cyber attacks. This naivety makes OT environments an easier target.
The authors of HAVEX certainly understand that OT environments are connected, since the method of transmission is via a downloadable Trojan installed on the websites of several ICS/SCADA manufacturers. What’s considered a very old trick in the IT world is still relatively new to those in OT.
It’s absolutely essential that organizations with ICS environments fully understand and embrace the fact that IT and OT are simply different environments within a single extended network. As such, cybersecurity needs to be implemented across both to produce a comprehensive security solution for the entire extended network. The most important way to securely embrace IoT is for IT and OT to work together as a team. By each relinquishing just a bit of control, IT can retain centralized control over the extended network – but with differentiated policies that recognize the specialized needs of OT environments.
We’ll never completely bulletproof our systems, but with comprehensive security solutions applied across the extended network that provide protection before, during, and after an attack, organizations can protect themselves from most of what’s out there. A significant step in the right direction is to understand that the airgap is gone forever; it’s time to protect our OT environments every bit as much as we protect our IT environments.

What do Walt Disney World, The Matrix, and Big Ben have in common? On the surface they do not share much. Each of these is special because everything that makes them tick, pun intended, are hidden from view of the consumers. We all intuitively know there is a great deal of complexity behind the scenes, but it is intentionally hidden from the users. This is the behavior consumers of cloud-based services also expect, even in the datacenter.
Today vendors are working hard to make their products and services more consumable in a nearly seamless fashion. They are accomplishing this by adding abstract control layers, open APIs with robust development kits, and enabling cross platform integrations. The recognition is that in today’s virtualized datacenter and the Internet of everything no technology is an island any longer. Efforts have to be made to make interoperability a priority in order to provide the polished experience that consumers have grown to expect. The question being answered is ‘Why doesn’t X communicate with Y?’ Read More »
