As part of our cloud strategy, we’ve recently released a VMware version of our cloud security offering. It allows cloud providers using VMware, as well as the cloud users themselves, to create an encrypted environment within minutes, while eliminating the complexity around encryption key management in the cloud without compromising trust and confidentiality. During this process we’ve engaged in many conversations with the cloud providers’ community to better understand their requirements, and equally important – their customers’ requirements. We’ve identified some interesting patterns with regards to cloud data security, which I thought would be beneficial to share. Where does it make more sense to integrate the encryption solution? One repetitive issue we’ve discussed with cloud providers’ was the ideal location for virtual encryption integration. In other words – wh... (more)

Crypto in the Cloud Secures Data in Spite of Providers

With companies increasingly worried about their data in the cloud, a number of providers have cropped up to offer various types of encryption Many studies have shown a chasm between cloud service providers and their customers regarding who is responsible for the security of the customer’s data: The providers put the responsibility in the hands of the customer, but the customer usually disagrees. According to a study conducted by the Ponemon Institute last year, for example, nearly seven in 10 cloud providers put responsibility for the security of a customer’s data with the custom... (more)

Encrypted Cloud Storage – The Missing Piece

Cloud computing brings many advantages including elasticity, flexibility, and pay-per-use. But when looking at cloud security, and specifically encrypted cloud storage the picture is much more complex. Cloud security (in IaaS and PaaS scenarios) is a shared responsibility. The cloud provider is responsible for securing the datacenter premise, the virtualization layer, and the Host OS, but it is the cloud customer’s responsibility to secure the host OS, work with an encrypted cloud storage and secure the application level. The missing piece by shel silverstein Cloud data security... (more)

Transparent Data Encryption in the Cloud

Transparent Data Encryption (TDE), sometimes also called Transparent Database Encryption, is one way to encrypt database content. TDE offers encryption at a column, table, and tablespace level. This makes TDE one of the more highly configurable ways to encrypt database content, though some of these configuration options come with a performance price. While TDE is well known in the Data Center, bringing it to the realm of Cloud Data Security does involve some new technical and operational questions. Database products that support TDE TDE is available as an “enterprise level” feature... (more)
