Improving security with cloud

Cloud-based security solutions will deliver protection to devices and data within or outside the standard network boundaries, says Steve Chappell of Wedge Networks.

The advent of cloud and mobility is forcing enterprises to reinvent their security approaches, said Steve Chappell, COO and EVP Sales and Marketing of Wedge Networks, at the recent NetEvents APAC conference in Singapore.

"As employees are increasingly connecting their personal devices to the office network and working remotely, enterprises need to think of new ways of securing their business. Today's mainstream security products can't address the threats in a cloud-connected world as they are designed to function within the old network connectivity paradigm," he explained. 

According to him, existing security products are inflexible for elastic computing, incapable of addressing the complexity of modern Internet traffic, and unable to enforce controls on Internet traffic at a granular level.

He thus advised organisations to turn to cloud-based security services that deliver protection from the network to better secure the business. Such security solutions require:

  • High performance security enforcement. Without this, networks will become clogged, causing end-customers to experience latency with their services.
  • Elastic orchestration for on-demand services to enable capacity planning.
  • To be embedded as a software-defined, network function
  • Exhaustive flow and content inspection of network, application and content.

"Security solutions should now move from endpoints and the enterprise into the cloud network to take care of future security needs. Instead of concentrating on protecting the device or endpoints, we're now focusing on protecting the data that is flowing out of those endpoints," he said.

Chappell also highlighted that service providers are in a "perfect position" to offer such cloud-based security solutions. "Since data going in and out of the enterprise has to pass through their service providers' networks, service providers are the perfect point to have software-defined, network function virtualisation for security installed," he said. By doing so, businesses can be assured that their data they receive from any endpoints are "clean and secure".
