One of the best new infrastructure developments available to enterprises is software-defined wide area networking (SD-WAN). It offers the ability to manage network traffic at discrete geographical locations over a single, centralized management application. It also prioritizes internet traffic, with mission-critical data transferred over multi-protocol label switching (MPLS) lines and less-critical data transferred over broadband.
SD-WAN offers some additional benefits, including the scalability that comes with any cloud subscription model, the ability to quickly connect a new branch location to the enterprise’s network, and increased agility. It can also improve network performance and reduce the cost of network maintenance.
While these benefits offer ample incentive for enterprises to implement SD-WAN solutions, deployment plans should include a strategy for addressing security. SD-WAN is not inherently insecure, but it is a dynamic network approach that must have a dynamic security strategy. There are two related reasons why security should be prioritized in an SD-WAN deployment plan:
The security landscape of SD-WAN is different. When implementing SD-WAN, it’s not as simple as tacking on a new technology to your existing network infrastructure. The routers are different than those being replaced, and IT needs to evaluate them for points of risk.
SD-WAN is a new technology with new security concerns. It’s simple: there haven’t been a lot of opportunities to see how hackers and malware approach SD-WAN solutions, so there’s still a lot of room for proactive evaluation of how SD-WAN introduces risks to the enterprise. SD-WAN is more open, and a branch location could provide access to the entire network if that single location is breached.
The Security Measures Necessary for SD-WAN
The beginning step for securing SD-WAN is to adopt a dynamic and proactive approach to security. The fluid nature of data transmissions, the decentralization of information, and the wide area of networks accessing data are all reasons to embrace a forward-thinking approach.
Your IT department must inventory and classify applications, evaluate end-to-end security visibility in any SD-WAN system considered for implementation, and run deep packet inspection. The overall purpose of SD-WAN implementation is the end-user experience, so it’s important to evaluate how a security concern could affect the customer.
