Bans Fail To Prevent Potential Enterprise Data Leakage Through Insecure File Sharing Cloud Services

The attractions of document sharing services are overriding security concerns in the rush to embrace BYOD strategies

Hamburg, 18th December, 2012 - Enterprise cloud synchronization provider TeamDrive is warning about the serious security risks being run by companies that ban document and file sharing services, such as Google Drive and Dropbox, without providing an encryption-based alternative.

According to the 1,300 respondents to a survey conducted by storage firm Nasuni, one in five employees is using Dropbox. What is more worrying is that 49 percent of users ignore corporate policies and use the service regardless, according to the Shadow IT in the Enterprise report.

This implies that the perceived benefits of having an unmanaged, unmonitored and unsupported element in business IT overrides any sense of responsibility. TeamDrive recommends accepting the irresistible trend by embracing it within a secure and manageable system such as its own.

Departments most likely to use file synchronizing services are IT, sales, finance and engineering - the latter three being sectors likely to have access to extremely business-sensitive data. Users around these departments are just as likely to be senior management as rank and file workers.

In May 2012, IBM was so concerned about the growing use of cloud file synchronization services that it banned its staff from using Dropbox and Apple's iCloud. It is likely that others will follow suit but the growing use of Bring Your Own Device (BYOD) strategies makes enforcement difficult, if not impossible.

Many of the services available seem to be secure because they use encryption between the user and the service but this protection is stripped away at the receiving end and the files are stored by the service provider in the clear. If a hacker, or even a rogue employee of the storage firm, gains access to a cloud drive, it could be costly if sensitive documents are being passed through the service.

Even when documents are encrypted at rest in the cloud, the providers, such as Dropbox, use a single key held in their system to unlock files as they are accessed by the document's owners or their sanctioned colleagues.

TeamDrive provides an individual service where a separate encryption key is generated for each user and stored on the client device. This means that TeamDrive cannot access the contents of any information stored on its systems and, if any files were stolen, a hacker would only have useless files encrypted to a 256-bit standard. The files are only available in the clear on the client devices and not anywhere in the cloud, giving true end to end security.

It is the service, not the cloud provider that is the attraction. Even if a ban on one provider's product is adhered to, staff would turn somewhere else. It is better to provide a secure system, like TeamDrive, to bring the renegades back into the security of the fold.

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...

With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
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" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
