Top Stories by Gilad Parann-Nissany

Israel-based startup Porticor launches this week with technology aimed at giving enterprises a way to encrypt data held in cloud computing services, including those from Amazon and Rackspace. Porticor Virtual Private Data is focused on protecting data at rest in cloud-based computing centers where customers rent disk space or servers, says Gilad Parann-Nissany, Porticor’s co-founder and CEO. What Porticor is doing that’s distinct is relying on a so-called “split-key” method in which the service to encrypt and decrypt doesn’t work unless both pieces of the key are together. The enterprise customer holds what Porticor calls the “master key,” and the idea is to foster trust by putting the customer in complete control. “We don’t have the customer master key,” says Parann-Nissany. In fact, the service provider doesn’t even see the master key in the encryption method th... (more)

Cloud Encryption for Cloud Providers

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 pa... (more)

Cloud Security – Implementing a Secure Cloud Backup Case Study

Secure cloud backup is a scenario which increasingly gains traction. It allows organizations to implement an off-site backup while maintaining costs at a minimum. In this blog post I would like to focus on a specific use case of secure cloud backup. The system we describe is comprised of an on-premise replication server, Porticor Cloud Security, and Amazon S3 as the final backup destination, all integrated by one of our fine cloud integrators. Secure Cloud Backup – The Business Need In this use case, an enterprise organization was struggling with an inefficient and costly offsite... (more)

Cloud Encryption and Key Management for Software Vendors

(Or: If you’re an ISV running on Amazon Web Services – This one is for you…) Over the past year, the trend of developing and delivering a software offering over a public cloud such as Amazon Web Services has grown dramatically. Software Vendors, both established and start-up companies, are using Infrastructure as a Service for its obvious advantages, such as cost effectiveness, redundancy, high availability, and probably the most dramatic effect for a software vendor – flexibility. A software vendor can make use of the IaaS provided APIs to automatically add servers, disks, back... (more)

Encrypted Database in the Cloud: Practical Considerations

Recently, in our post on Database security in the cloud, we reviewed the threats against database installations in the cloud and best practices for protecting your data. A number of customers have asked us follow-on questions: Which database brands are open and tested with these techniques? What are the most significant gotchas? What performance, scalability and fail-safe characteristics can they expect when securing their database in the cloud? We have found that all the major relational database brands (MySQL, Oracle, Microsoft SQL Server, and IBM DB2, among others) can work wel... (more)
