Cloud computing brings many advantages including elasticity, flexibility, and pay-per-use. But when looking at cloud security, and specifically encrypted cloud storage the picture is much more complex. Cloud security (in IaaS and PaaS scenarios) is a shared responsibility. The cloud provider is responsible for securing the datacenter premise, the virtualization layer, and the Host OS, but it is the cloud customer’s responsibility to secure the host OS, work with an encrypted cloud storage and secure the application level. The missing piece by shel silverstein Cloud data security threats Some aspects of securing virtual servers and storage are not dramatically different from securing a physical server and the same basic rules still apply.  Enforcing a strong access control policy, disabling unnecessary ports, and hardening the application layer are still valid and nec...

Cloud Encryption at The Application Level For Cloud Security And Full Compliance

It’s a common sense fact that a cloud encryption solution needs to fit the specifics of a requirement. Some scenarios need out-of-the-box solutions that require no changes to existing application code. Other scenarios demand changes to application code. A recent article by Ken Smith pointed out the limitations of out-of-the-box solutions, and militated for application-level code implementing cloud encryption solutions. Application-level solutions do have definite benefits for compliance requirements. If you want to be sure that cloud database administrators cannot read sensitive... (more)

PCI Compliance in the Cloud: What You Need to Know

Cloud Computing – the buzz words of the technology sector this decade: if you’re not already doing it, you’re missing out.  Articles have been written.  Experts have been crowned.  Events have been attended.  We all agree – the cloud presents opportunities for cost savings, elasticity, and scalability. But for companies that are bound by Payment Card Industry Data Security Standard (PCI DSS), securing financial data in “the cloud” presents new issues. How is the Cloud Different? Securing brick and mortar businesses was one thing, securing data centers and hardware was an added ... (more)

Top Three Reasons to Switch to Cloud Data Security

Companies are increasingly moving their data security to the cloud. By the 2015, 10% of overall IT security enterprise product capabilities will be delivered in the cloud, according to a study conducted by Gartner. In fact, the cloud data security market is expected to reach $4.2 billion by 2016. Are there compelling reasons to move your own data security to the cloud? I am a firm believer that cloud security is a godsend to companies dealing with sensitive information, particularly small and medium sized enterprises (SMEs). Here are the top reasons to consider moving your data se... (more)

Wisdom for the New Year: Never Sell Cloud Computing

How to sell Cloud Computing? We could do it the Dilbert way. Say what you will, it hits a button. Or we could do it the old fashioned way. Not convinced? Actually this is why Porticor never "sells" cloud. Our approach is always to assume the IT Customer has Decided what are the benefits they expect (economics, agility, and so on) Evaluated what they would feel comfortable putting in the cloud Understands that – in IaaS/PaaS – they still retain some responsibility for their security Started asking the questions: “how to meet our responsibility, how to do security reasonably, and...
