One of the primary challenges with network security in cloud computing is an enterprise’s lack of network visibility to monitor and tackle suspicious activity. Computing on a public cloud relinquishes control of networking and data from the user or enterprise to the cloud service provider. Enterprises face other cloud computing security concerns. The issues revolve around privacy, compliance, and data recovery.
The cloud is a popular option among both individuals and enterprises. In fact, according to a RightScale study, “81 percent of enterprises have a multi-cloud strategy.” With surging reliance on the cloud for networking demands, it’s imperative to fully understand the cloud computing risks and how to best implement a cloud strategy.
Here are some steps to achieve network security in cloud computing.
Network Security in Cloud Computing
Comparatively, cloud networking features more security than traditional networking. Some of the security benefits include the option to encrypt data, provide multi-factor authentication, install firewalls, and enable data loss prevention.
Stratoscale identifies the following four principles of network security in cloud computing:
Isolation between multiple zones should be guaranteed using layers of firewalls.
Network controls for traffic to and from their applications.
End-to-end transport level encryption should be used by applications.
Standard secure encapsulation protocols such as IPSEC, SSH, SSL should be used when deploying a virtual private cloud.
In addition to these four principles, it’s essential to hold public cloud service providers accountable to their service level agreements (SLA). Viavi states in a blog post that “an SLA by itself is not enough to guarantee that your organization receives the level of service promised. Since it is not in the provider’s interest to inform a client when its quality of service fails, we must rely on an independent view of WAN link connections.” Investing in network performance management (NPM) tools gives enterprises access to monitor network performance and ensures that the cloud service provider is fulfilling requirements.
