Fresh Perspectives on Consumerization and BYOD – Part 3
This is the third of a three-part blog series exploring the issues and challenges with consumerization and BYOD. In part 1 of this series, we examined the challenge of dealing with the scope and diversity of consumerization. In part 2 of this series, we took a closer look at why the network plays such an important role in making an effective strategy. In this segment, let’s take a closer look at how the next-generation firewall provides the means to assert control.
It’s clear that the network is the right place for IT to enforce control between applications and users, and that’s true regardless of what device is being used. What the traditional network lacks, however, is the control structure to address applications, users or devices as policy criteria. For example, the legacy firewall can’t make the determination of what applications, users and devices are on the network, even though it is in the right location for enforcement. A VPN might know who wants access to a network after asserting authentication credentials, but it has no idea how to tie identity to the firewall’s enforcement of what traffic may pass. Device identification and blocking methods range from the ineffective (such as MAC address filtering) to the impractical (such as network access control). And some controls for handling consumerization, such as identifying whether an application is being accessed from an IT managed asset (and thus permitted to locally store application data), are not addressed by any traditional network security product. …Continue reading

Fresh Perspectives on Consumerization and BYOD – Part 2
This is the second of a three-part blog series exploring the issues and challenges with consumerization and BYOD. Part 1 is available here. This blog entry will explore the role of the network in addressing unmanaged devices.
“Why do I need Mobile Device Management?”, said the man sitting across the table from me.
I recently spent some time with one of our customers, and the director of network security opened the meeting in that manner. At first, I thought he was asking me a question, and I started to talk about the important role that Mobile Device Management plays with respect to managed device policy, and how that integrates with the Palo Alto Networks firewall. However, I later realized that he was opening a discussion to talk about his perspectives on BYOD.
We started talking about how there’s a general belief that consumerization and BYOD are a device proliferation problem that needs to be controlled. As we talked, we both agree that the heart of the matter, the real issue is dealing with unmanaged devices, and that’s a network control problem.

Fresh Perspectives on Consumerization and BYOD: Part 1
This is the first of a three-part blog series exploring the issues and challenges with consumerization and BYOD. This first post will dive into the landscape of existing approaches to consumerization and some of the issues that arise at many enterprises.
Two of the biggest challenges IT departments face today are consumerization and its close cousin, Bring Your Own Device(BYOD). Both are hot topic issues, driven by the popularity of consumer computing platforms but, to be clear, these two terms are not one in the same. Consumerization broadly describes the effect of employee preference coming into play on the technology that IT provides, based on personal affinities to the functionality and usability of a given smart phone, laptop operating system or tablet. BYOD goes one step further, as employees purchase their own devices for use at work, with or without the support of the IT department.
