NIST Weighs In on the Cloud

Organizations are entitled to strong cloud data security measures from their vendors

NIST released a new publication entitled Cloud Computing Synopsis & Recommendations (Special Publication 800-146) that describes in detail the current cloud computing environment, explains the economic opportunities and risks associated with cloud adoption, and openly addresses the security and data privacy challenges. NIST makes numerous recommendations for companies or agencies considering the move to the cloud (including delivering a strong case for uniform management practices in the data security and governance arenas).

The report highlights several reasons why cloud-based SaaS applications present heightened security risks. As a means to offset the threats, NIST's recommendation on cloud encryption is clear-cut: organizations should require FIPS 140-2 compliant encryption to protect their sensitive data assets. This should apply to stored data as well as application data, and for Federal agencies, it's a firm requirement, not simply a best practice or recommended guideline.

Regrettably, some vendors are misleading the market with claims that sensitive data in the cloud does not require FIPS 140-2 validation, and instead lesser validation is sufficient. Customers should challenge these sorts of claims and insist on FIPS 140-2 validation if encryption is selected as the preferred technique to secure sensitive data to the cloud. And they should ensure that the functionality of their SaaS applications, such as Searching and Sorting, is preserved, even when this level of strong FIPS 140-2 encryption is in place.

Regarding data governance and regulatory cloud compliance, NIST also recommends that consumers require cloud providers to meet all international, Federal, and state statutes regarding data protection, privacy, and residency. This is a broad, complex area in which the laws continue to evolve, and consumers are ultimately liable if legal issues arise. Many enterprises believe tokenization technology is best suited to address these "data residency" concerns, since tokens can be used to replace personally identifiable information in the cloud, ensuring the original data never leaves their local jurisdiction. Again, preservation of the cloud application's functionality is critical - so enterprises need to ensure they are not being asked by their vendor to sacrifice on SaaS usability in order to get the strong level of protection required to adequately secure their sensitive business information.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository. Ochandarena discusses a whole new way to think about your next...

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people. They are not optimized for low- or battery-powered devices or for IoT applications with infrequently transmitted data. Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
