Windows 10, BYOD and IoT: New Strategies for Securing the Network

The appeal of  “free” is undeniable. Perhaps that’s why Microsoft (News - Alert) decided to offer Windows 10 as a free upgrade. Just as the free version 8.1 enjoyed higher download rates than version 8, it is estimated that Windows 10 will be downloaded to about two-thirds of all personal computers in the first 12 months. It may seem like a win for consumers, but it may create a huge gap between enterprise IT teams and employee devices.

Another factor in the release of Windows 10 is that, for the first time, Microsoft plans to expand Windows 10 to an unlimited number of devices via the “Internet of Things” (IoT). The IoT is becoming an increasing topic of conversation both in and outside of the workplace, in particular in discussions around how to secure these connected devices.

In addition to the IoT, enterprises must also deal with the BYOD (Bring Your Own Device) phenomenon. These two new technology realities present a much larger issue: how do you securely manage the onslaught of virtually invisible devices that are connecting to your corporate network?

An agent has to be running on the device for the IT operations team to be able to detect it – if you’re working with traditional endpoint security management. Since users will be upgrading their personal devices to Windows 10 on a massive scale—and therefore will not have agents—IT administrators need a way to identify, evaluate and secure all the new Windows 10 endpoints that are connecting to their networks. Security through agentless visibility empowers IT to see how many endpoints are accessing the enterprise network and be proactive about only allowing compliant devices to access valuable applications and data.

While BYOD is convenient for employees, it can cause a real nightmare for IT organizations. The truth that can’t be ignored is that BYOD is here to stay, and steps must be taken to safely embrace it. To provide a secure network, enterprises must include:

As the network and the number of things it’s connected to expand, keeping it safe becomes increasingly complex. Most networks today include an accumulation of security products added over time, layered on top of each other vertically and laterally.  Add the challenge of IoT, BYOD and free upgrades—such as the Windows 10 release—and the result is a complicated infrastructure where full protection from cyber attacks is a daunting task.

It’s not realistic to prevent employees from upgrading to Windows 10 just to buy some time.

Upgrades of this nature have become the norm, and it’s better to embrace rather than fight the growing trend. The last two years show that no matter how robust the external defenses, a determined and persistent adversary can find a way to infiltrate a corporate network.

Best practices for IT organizations today include a security strategy with policy-based network access, the ability to share real-time context and visibility into both managed and unmanaged devices. This well-rounded approach will help to bar cyber criminals while granting access to employees, no matter their device or software upgrade. IT security teams will also then be prepared to deal with IoT devices as they make their way onto the network. “Free” is a great word, but when it comes to securing enterprise network environments, “visibility” is an even better one.
