There are several major trends affecting the complexity of network cyber security, including increased cloud migrations, the introduction of the Internet of Things (IoT) and its fleets of devices, and the spread of employee mobility. Each of these drivers introduces an increased flow of data in and out of the network, leading enterprises to consider a multi-protocol label switching (MPLS) alternative.
That alternative is the internet. By deploying a software-defined wide area networking (SD-WAN) solution, companies are able to identify an MPLS alternative that lowers cost and enables the network administrator to prioritize a video conferencing session over an employee viewing YouTube on break.
The challenge is that while this solution, which also works as a virtual private network (VPN) alternative, handles the cost of the data flow better, it also requires a significantly different security approach. With an increase in the number of endpoints thanks to IoT devices and mobile devices, the security plane becomes broader and more complex. The centralized network model is no longer relevant, with its hub-and-spoke design. Enterprises need a more complex, flexible solution to handle the complexity of the IT environment.
For the past two decades, employees have become increasingly mobile. As this reality becomes more and more a part of everyday working life, employees are accessing data and applications outside the company network. Whether they are at the airport or working at the local coffee shop, they expect to work consistently at any location.
In addition, migration to the cloud means that centrally located network infrastructure, with its stacks of hardware, are increasingly irrelevant. The security approach used for a centralized network with firewalls is no longer enough because many business processes are happening outside those parameters.
Using an MPLS alternative that breaks internet traffic out to branches or segments it by application type or user requires a parallel examination of the cyber security approach. Neither the network solution nor the security solution should be addressed in isolation, nor should the process of relocating solutions into the cloud.
As opposed to quick fixes that address specific areas, like securing a VPN alternative or addressing the latency that occurs when IoT technology is introduced, enterprises need a comprehensive approach to network infrastructure and cyber security. A cloud-based network security solution is a high-performance solution that keeps pace with digital transformation and the automation that enterprises need to make cyber security manageable within a cloud environment.
