Amazon S3 Server Side Encryption & Software Defined Key Management

encryption key management Cloud Key Management AWS security AWS Encryption  amazon s3 server side encryption Amazon S3 Server Side Encryption & Software Defined Key ManagementStrong data encryption is a critical line of defense against cyber criminals and spies. Amazon has always taken care of the front lines with their strong infrastructure with security mechanisms like multi-factor access control systems in AWS datacenters, availability zones, built-in firewalls, private subnets, etc.

Now, with the addition of Server Side Encryption with Customer-Provided Keys, Amazon protects the data you store with Amazon S3 server side encryption. Even better, Amazon encrypts your data using a key you provide; a key that is never stored by Amazon. Thus, they have successfully protected your data from prying eyes – even their own.

The result is that you no longer need to lose sleep over storing encryption keys with Amazon. You can easily encrypt your data with your own key. Thanks to Amazon, encrypting is easy and secure!

How do you manage your Amazon S3 encryption keys?

Herein lies the real issue now facing each of AWS’s customers. Amazon has provided you with an excellent arsenal: strong infrastructure, easy encryption. But your part of the shared responsibility model is to properly manage your encryption keys. You need:

  • A way to randomly and securely generate Amazon S3 encryption keys
  • A controlled system to store, manage, and retrieve the many keys required for each S3 object
  • A system that ensures that keys are kept within your control; thus complying with regulations like HIPAA and PCI.
  • A software-defined automated solution that eliminates the need for cumbersome, non-scalable, and expensive hardware security modules (HSMs)

AWS Encryption Key Management: What are the options?

You have three options when it comes to managing encryption keys for AWS.

1.       Hardware security modules (HSMs)

HSMs are reasonably secure. To manage keys outside the cloud, an HSM is a great option. Unfortunately, in cloud scenarios, they have major drawbacks. First, being hardware based, they limit the benefits of the cloud, especially auto provisioning, orchestration and geographic dispersion. Also, they are far more expensive than software-defined solutions.

2.       Cloud-based HSMs

Still based on hardware, cloud-based HSMs offer limited scaling and do not support auto-provisioning. Because they are complex systems, operational overhead is high, and involves up-front costs. Also, with cloud-based HSMs, you still deal with the problems of securing a key cache in the cloud and access credentials.

3.       Software-defined key management

To work with your software-based cloud-computing scenario, the best option is a software-defined cloud key management system. Such a system enables you to consume key management as a service, while ensuring data security that is stronger than hardware. It can be automated with a RESTful API. Its benefits are much like those which prompted you to migrate to cloud storage: scalability, flexibility, and agility. Software-defined key management costs a fraction of hardware-based modules and is more effective at securing your cloud data. Furthermore, it is compliant with laws and industry regulations. Two examples for such systems are Porticor Cloud Security, and HP Atalla Cloud Encryption

Key Management for Amazon S3 Server Side Encryption

Amazon, one of the most customer-centric companies in the world, has developed a cloud computing system that is great for customers. They provide you with a safe place to put your data. Now, they even provide you with a way to protect the data you put there. The only thing they can’t do (and rightfully so) is protect that protection.

Managing the encryption keys remains your responsibility because it must be your responsibility to ensure the integrity and ownership of your data. If Amazon could manage the encryption keys for you, they would . . . but by doing so, they would puncture a hole in your security (and defy regulations like HIPAA and PCI).

Encryption key management remains solely your discretion and the only way to do it in a manner that is secure, compliant, and cost-effective is with software-defined key management.

For a detailed technical example and an implementation sample, see this post.

Between 2005 and 2020, data volumes will grow by a factor of 300 – enough data to stack CDs from the earth to the moon 162 times. This has come to be known as the ‘big data’ phenomenon. Unfortunately, traditional approaches to handling, storing and analyzing data aren’t adequate at this scale: they’re too costly, slow and physically cumbersome to keep up. Fortunately, in response a new breed of technology has emerged that is cheaper, faster and more scalable. Yet, in meeting these new needs they...
Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lead...
In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
