IDG Contributor Network: Encryption is the foundation of the new data center
For decades, encryption was an arcane art. Encryption was slow, clunky and highly complex, and as a result, the vast majority of data in the data center resides on storage systems in the clear. Sensitive data has historically been protected by IP segmentation and firewalls with IPS modules.
This model is now changing.
As workloads in the corporate data center begin to migrate to the public cloud, the need to encrypt data in motion and at rest becomes foundational. In the public cloud, it is much harder to rely on the traditional approaches of wrapping select data with firewalls and IPS systems. At the same time, it is much easier to post a heap of sensitive data to an object store such as Amazon S3 and inadvertently leave it open to the unwashed Internet. Customer-controlled encryption is becoming a necessity for the enterprise hybrid cloud.
