Working Without Walls – How to Protect the Data on Your Network Beyond Traditional Perimeters with Software Defined Networks

Users have grown to expect instant access to their data, wherever they are. Convenience can facilitate increased productivity, as employees are able to work beyond the traditional boundaries of the workplace. Combine this with the rise of BYOD (Bring Your Own Device) culture, coupled to the assortment of devices users already juggle for work – laptops, smartphones, tablets – and it’s easy to see that while productivity is aided by these developments, a balance must be found between convenience and security.

This becomes another challenge to provide information assurance, a challenge that’s ever-increasing in our digital age where traditional perimeters no longer apply to the work environment. How can the valuable information contained within these networks be kept secure?

Cloud computing has been one way in which organisations have attempted to answer the calls of their employees for more flexible working solutions in the era of the workplace-without-walls, with data centres evolving into highly virtualised environments, but gaining that vital level of assurance is difficult when peering into the murky world of cloud.

Networks which rely on a cloud provider can open up the information they carry to increased risk of attack, as cloud providers themselves become increasingly attractive targets for hackers owing to the huge and varied amount of information they hold on a variety of organisations. While cloud providers will often deploy thorough security controls of their own, the onus of protecting an organisation’s data in the cloud ultimately falls to the organisation.

One possible solution which could provide benefits for businesses that generate large, unpredictable data flows which require a real-time response is through Software Defined Networking (SDN). Traditional enterprise networks rely on a hierarchical topology as the basic architecture, which limits their ability to support the requirements of a modern business in a cost-effective manner. SDN removes these constraints, and automates the configuration while allowing for centralised control of the network. SDN has been designed with high-bandwidth, dynamic modern data centres in mind.

Uptake for Software Defined Network technology is on the rise, with even conservative estimates putting the size of the SDN-WAN market at $1.3bn globally by 2020. Couple this with the race towards 5G technology, itself highly likely to be underpinned by SDN architecture, and it takes no great leap of imagination to envisage SDN will soon be high on the target list of today’s sophisticated hackers. Security should therefore be a key consideration when embarking on a project to implement SDN across an organisation, and that’s where Commissum comes in.

We’ve produced a whitepaper on Software Defined Networking, which outlines the many benefits of moving company networks to its agile architecture and addresses the security concerns which are related to implementing SDN as part of a corporate network.
