Cloud computing without VPN is security risk, Part 2

By Bernd Reder

Let's revisit Tuesday's post on cloud computing and VPNs, diving deeper into how organizations can ensure their employees are using the cloud securely. The answer is, via a VPN (Virtual Private Network). This applies to any cloud computing environment - be it public, private or the popular hybrid cloud models. The VPN solution should offer the greatest possible flexibility, including support for IPsec and SSL and the capability to enable seamless roaming between various communication media (such as LAN and Wi-Fi) . Furthermore, it is essential that the VPN solution enables an organization’s IT administrators to centrally manage all clients and components of the VPN infrastructure.

Cloud VPNs instead of Do-it-yourself VPNs

However, many organizations are not equipped to establish a company-wide VPN on their own and instead need a service provider to take on this task, either by providing a Virtual Private Network as a Service (VPNaaS) or remote access out of the cloud. Either of these solutions provides an alternative to the do-it-yourself VPN approach. Rather, cloud VPNs enable employees of a company to securely access all network resources in the cloud environment - applications, data and storage capacities - from anywhere.

When considering cloud VPNs, organizations should consider a service that supports all end-devices that are used throughout the company - from desktops, notebooks, tablet PCs to smartphones. Ultimately, no matter which option a company takes to ensure secure cloud access, the organization reaps the benefits of the cloud and lowered IT costs.
