Businesses can do a lot to protect themselves. The FCC issued a Tip Sheet for small businesses to promote employee security training, firewalls, securing of WiFis, and more. But for business operating in (or migrating to) cloud environments; data security, cloud computing security issues, and challenges take on  new meanings and require new strategies. Security in the Cloud: Unique Challenges In the cloud, data security poses new risks and challenges. We are no longer concerned just with burglars breaking into our offices to steal computers, but rather with the data belonging to complete systems deployed to the cloud.

Four Great Tips: Cloud Security for Big Data

The combination of cloud computing and big data is a match made in heaven. Big data requires a flexible compute environment, which can scale quickly and automatically to support massive amounts of data. Infrastructure clouds provide exactly that. But whenever cloud computing is discussed, the question comes up: What about cloud security for big data? When it comes to cloud security in a big data use case, the expectation is that any security solution will provide the same flexibility as the cloud without compromising the overall security of the implementation. When taking your... (more)

Cloud Security Myths: Busted

In a Feb 2014 survey, 94 percent of organizations surveyed reported running applications or experimenting with infrastructure-as-a-service.[1] According to research firm Nasumi, there is over one exabyte currently stored in the cloud. An exabyte is over a billion GB.[2] Considering the amount of data in the cloud and the growing rate of adoption for sensitive use cases, it is natural that securing our data in the cloud is a concern. But, cloud security, though rightfully a central concern, should not be a hindrance to aggressively moving workloads and applications to the cloud. ... (more)
