Cloud Security: Security Cloud Backup deployment use case analysis

Security Cloud Backup has been a growing concern because it allows businesses to keep costs to a minimum while deploying offsite backups. In this article, we will analyze a specific use case for a secure cloud backup, which is comprised of the systems we describe in this article: An Enterprise internal replication server, Porticor Cloud security, and Amazon S3 as the final backup destination.

Secure Cloud Backup: Business needs

In this use case, companies are struggling with inefficient and costly off-site backup infrastructures that need to manage an ever-expanding database. Offsite server farms are very expensive to operate and maintain, while tape and recovery methods are time-consuming. In addition, the company is unable to meet regulatory requirements in terms of availability of data. To eliminate the complexity of this backup approach and reduce costs, emind BAE Integrators deployed an internal dedicated server that mirrors directories and volumes on the local network and then copies data to Amazon S3. But this approach has a key element: cloud data security and encryption, which is Porticor.

Consider cloud security and cloud encryption options

One of the most concerned issues with enterprise deployment Cloud encryption is "data confidentiality" or, in other words, who controls the encryption key and is likely to access the data. Some cloud service providers provide data encryption as part of their services, but as cloud service providers manage and maintain your cloud encryption keys, they may see your data. Rich Mogull points out that a secure alternative is an enterprise internal Key Management Server, but the cost of such a server is expensive (in terms of operational and capital expenditure) and limits the flexibility of cloud computing.

Secure Cloud Backup: Task complete

In order to protect information security while avoiding the above problems, Porticor's virtual private data is integrated into the backup use case. The end result is a highly scalable, resilient, and secure backup solution. The Enterprise field server mirrors the data and transfers the data to a pre-configured Amazon S3 bucket, however, Porticor encrypts each object as the data is transferred to the S3. Each object is encrypted with a unique cryptographic key, and the customer holds a single "project" key, which allows the automation of the key management cycle without the need to share the encryption key with anyone else.
