Toward a More Confident Cloud Security Strategy

Confidence in cloud encryption depends on understanding on where it needs protection

The cloud has hit the mainstream. Businesses in the United States currently spend more than $13 billion on cloud computing and managed hosting services, and Gartner projects that by 2015, end-user spending on cloud services could be more than $180 billion worldwide. It is estimated that 50 percent of organizations will require employees to use their own devices by 2017, which will depend on shared cloud storage. All of this requires encryption.

Organizational deployment of encryption has increased significantly in recent years. Its use spans everything from encrypting data in databases and file systems, in storage networks, on back-up tapes, and while being transferred over a public and internal networks. Although this might seem that we are moving in the right direction when it comes to enterprise data protection, there's a real risk of creating fragmentation and inconsistency - referred to as encryption sprawl - as different organizations deploy diverse technologies in different places to secure different types of data. Adding fuel to the fire, the cloud poses its own unique threats and challenges. With an undeniable value proposition, it seems clear that the cloud is inevitable and that protecting data within it will be a top priority.

The 2014 Encryption in the Cloud report reveals that more than 50 percent of businesses surveyed have sent confidential or sensitive data to the cloud. Only 11 percent of respondents say that their organization has no plans to use the cloud for sensitive operations, down from 19 percent just two years ago. It is heartening to see that use of encryption to protect that sensitive data in the cloud is also increasing, but it's disturbing that over half of the respondents who store sensitive data in the cloud report that their data is "cleartext" and therefore readable by anyone who can access it.

Cloud Confidence Through Key Management
Cloud usage may be ubiquitous, but opinions on securing data in it are no unanimous. Viewpoints abound when it comes to deciding where and how to apply encryption in the cloud. The report shows an almost equal split between those who encrypt data before it is sent to the cloud and those who choose to apply encryption directly within the cloud. Regardless of approach, key management remains a pain point, as businesses tread the line between trust and control between their own organization and the cloud provider.

In fact, key management is foundational to an effective encryption strategy. Although many regard encryption itself as being black and white - data is either encrypted or not - the reality is that there is such a thing as good or bad encryption. Much of the variance comes down to implementation and key management - a point that became crystal clear with the recent "Heartbleed" vulnerability in OpenSSL. With this in mind, we were pleased to see that 34 percent of respondents report that their own organization is in control of encryption keys when data is encrypted in the cloud. Only 18 percent of respondents report that the cloud provider has full control over keys.

Letting the cloud provider hold the reins is a dicey proposition. If the provider holds the encryption keys, how do you know they're safe? If someone shows up with a lawsuit or subpoena, will the cloud provider release these keys without your knowledge? From a criminal's perspective, stealing keys is far more interesting than stealing data. Stealing data is the modern equivalent of stealing money, yet stealing keys is like stealing the machine that makes the money - an attack that keeps on giving, or to be more accurate, an attack that keeps on taking!

As demand for cloud services continues to rise, security threats to data stored in the cloud will rise as well. Confidence in cloud encryption depends on understanding on where it needs protection, what the consequences are of it being compromised and what level of protection is required. Best practices dictate a cloud encryption strategy to protect critical data while maintaining control of keys.

"We've just seen a huge influx of new partners coming into our ecosystem, and partners building unique offerings on top of our API set," explained Seth Bostock, Chief Executive Officer at IndependenceIT, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
Mobile, social, Big Data, and cloud have fundamentally changed the way we live. “Anytime, anywhere” access to data and information is no longer a luxury; it’s a requirement, in both our personal and professional lives. For IT organizations, this means pressure has never been greater to deliver meaningful services to the business and customers.
Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...

Malicious agents are moving faster than the speed of business. Even more worrisome, most companies are relying on legacy approaches to security that are no longer capable of meeting current threats. In the modern cloud, threat diversity is rapidly expanding, necessitating more sophisticated security protocols than those used in the past or in desktop environments. Yet companies are falling for cloud security myths that were truths at one time but have evolved out of existence.
Public Cloud IaaS started its life in the developer and startup communities and has grown rapidly to a $20B+ industry, but it still pales in comparison to how much is spent worldwide on IT: $3.6 trillion. In fact, there are 8.6 million data centers worldwide, the reality is many small and medium sized business have server closets and colocation footprints filled with servers and storage gear. While on-premise environment virtualization may have peaked at 75%, the Public Cloud has lagged in adop...
