Data at rest has long been protected by technology called public key infrastructure (PKI), in which data is encrypted when it’s created by a public key and only decrypted, in theory, by an authorized person holding the private key. But extending this type of data protection to the cloud can be complicated.
The migration to the cloud has introduced a new set of complex security issues for IT teams to manage due to the lack of direct control over the security of the data. Moreover, cloud providers believe that data security is a shared responsibility, where the service provider assures physical security and the subscribers must secure their servers and data. Presumably this would include a strategy for encryption and key management which requires that the keys be stored outside the cloud rather than in it.
Startup security company Porticor just released a solution that addresses the concern about data at rest in the cloud. Porticor offers a split key encryption solution where the cloud customer is the only one who knows the master key. What’s more, Porticor handles all the complexity of encrypting data so the customer barely needs to think about it. The security and convenience is all in the unique implementation of key management.
SECURITY STARTUPS: 6 new security companies to watch
The fundamental problem of encrypting data in the cloud is where to store the keys. The customer can’t store the keys on a disk in the cloud because they could be vulnerable to hackers. The customer could allow a vendor to store its keys, but that means putting trust in a third party. The customer could bring the keys back into his own data center, but that seems to defeat the purpose of outsourcing data center services to the cloud. Porticor now offers an alternative for key management that is both simple and secure.
Porticor’s approach is based on the concept of the safe deposit box that has two keys — one for the customer and the other for the banker, or in this case, the Porticor Virtual Key Management Service. Just like the safe deposit box, the customer can’t decrypt the data without the key held by Porticor, and Porticor can’t decrypt the data without the master key held by the customer. In practice, the customer actually has one key per project, which is usually an application. Porticor has thousands of keys, one for each file or disk belonging to that project. Still, the keys must pair up in order to provide access to the encrypted data.
Beyond the keys being split between the customer and Porticor, the unique part of the solution is the keys themselves are encrypted by the customer’s master key, which only the customer holds and knows. As a result, Porticor holds project keys but the vendor can’t read them because they are encrypted. By encrypting the “banker” keys with the customer master key, Porticor gives the customer complete mitigation of end data protection. The customer must write down the master key and literally store it in a steel box. Once that is done, no one in the world other than the steel box ever sees the key. (Another option is to put the master key in an escrow service.)
Architecturally, the Porticor solution sits between the cloud based server and storage, ensuring that every bit of data between the servers and the storage is encrypted and every bit of data moving from storage to the servers is decrypted for customer initiated processes. The piece in the middle is the heart of the Portico solution, the Virtual Private Data (VPD) application. VPD is a virtual appliance that encrypts any disk or storage array with encryption algorithms such as AES-256. VPD retrieves the “banker” keys as well as requesting from the customer its key.
Porticor says this is military-grade security since only one party — the customer — holds the master key to unlock the data. (Hint: Don’t lose the master key or you’re up the creek without a paddle.) The master key only needs to be brought out of the steel vault when the entire server cluster is rebooted, which should be a rare occurrence. When new application servers are created, they inherit the encryption automatically through the VPD.
Security- and risk management-wise, the Porticor process does not save a “plain key” to any disk. Then, even if a hacker has penetrated the service provider’s network searching for data, the hacker will not see anything to steal.
The Porticor solution is designed to work with any cloud implementation. Today, Porticor has established partnerships with Amazon Web Services (AWS) and Red Hat, making the choices of those two services extra easy.

All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud.

What are the new priorities for the connected business? First: businesses need to think differently about the types of connections they will need to make – these span well beyond the traditional app to app into more modern forms of integration including SaaS integrations, mobile integrations, APIs, device integration and Big Data integration. It’s important these are unified together vs. doing them all piecemeal. Second, these types of connections need to be simple to design, adapt and configure...

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" ...

Both SaaS vendors and SaaS buyers are going “all-in” to hyperscale IaaS platforms such as AWS, which is disrupting the SaaS value proposition. Why should the enterprise SaaS consumer pay for the SaaS service if their data is resident in adjacent AWS S3 buckets? If both SaaS sellers and buyers are using the same cloud tools, automation and pay-per-transaction model offered by IaaS platforms, then why not host the “shrink-wrapped” software in the customers’ cloud? Further, serverless computing, cl...

As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and micro services. While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your contain...
