What are the most important aspects of a cloud security policy?

Cloud security refers to network security, computer security and data security. So a cloud security policy will include a set of technologies and controls which are undertaken for protecting data and applications as well as the cloud architecture. Before moving to the cloud, client enterprises need to have a proper understanding of all the potential risks and benefits of cloud security policy. This will help them to set pragmatic expectations with the vendor.

One of the important risks which need to be addressed by the cloud security policy is that of loss of governance. Clients give up much of their control to vendors in public clouds. So, issues that were handled by them are now left to vendors to resolve but these many not be stated in the SLA. The responsibility over different aspects of cloud security may be shared by both clients and providers but this needs to be clarified in the policy. Authorization and authentication is necessary because in cloud hosting, resources may be accessed by individuals from any place. The client must also ensure that the vendor has proper certifications to show its compliance with the industry standards or allow the customer to conduct audits.

The service agreement must also state ways to handle security incidents; while the detection and management of breaches will be taken care of by the vendor, clients have the right to be notified about them. The security of the infrastructure is delegated to the provider but businesses must consider the need to apply greater controls over applications through the cloud security policy. An important aspect of cloud security policy is data protection; the key threats are that of data unavailability and data loss and release of sensitive information. The security policy needs to also consider the malicious behavior by individuals working within the organization. Finally, the cloud security policies must also take into account service unavailability because of hardware or software failures and provider's business failure which makes data or applications unavailable to businesses for some time.

The need for cloud security is increasing with each passing day because of continuous data and security breaches. Cloud computing is a model that allows on-demand access to a shared pool of configurable resources like network, server, storage, application, and services. The main benefits of cloud computing are in self demand, self-service, wide network access, resource pooling, rapid elasticity, measured service, and standard pricing. The cloud model can be applied to several services and infrastructure and software platforms. Moreover, you will have access control, data encryption, compliance, and auditing. These are the important security measures in the cloud.
