Regardless of innumerable benefits of cloud computing, there are still many companies which need to implement cloud technology within their organization. “Data Security” is always an unavoidable issue to the organizations who are planning to adopt cloud services and for the cloud service providers who wants to settle their business into the cloud computing market. The big question that surrounds all cloud vendors is the data security and what they can do best in order to maintain the customer trust & their data secure.
There is a series of questions that comes into mind while making a move to adopt a cloud environment like:
- Is it Secure?
- Is it really cost effective?
- Which vendor is to go for?
- What benefits does it has over on premise infrastructure?
- Can unauthorized users gain access to the confidential data?
The answer to these questions depends upon the business requirements, the kind of data/application you wish to host, the data is critical or non-critical and of course the budget allocated for the security aspects. Client expects the implementation, the access control and encryption which protects data from hacking. According to security perspective, responsibility of security is maximum in IaaS model (user has more control on their data than the cloud vendor) and as the client moves up from PaaS to SaaS model it decreases and the vendor responsibility grows.
Cloud vendors uses different encryption techniques for different data types (i.e storage data, processing data, transmission data) to keep data safe and keep up the customer trust.
The security level that a vendor offers can also be measured by the kind of security certifications that it has. Also, there are lot of industry specific certifications available which helps organizations to choose the vendor that satisfies their business needs.
- ISO 27001 – is a kind of security certification that address requirements, implementation, measurement and codes of practice.
- CSA STAR certified cloud vendors offers service capabilities transparently. Alibaba is the world’s first company to obtain CSA STAR gold medal certification.
- SOC 1 – certification addresses quality of control on financial reporting. SOC 2 and SOC 3 is related to security, availability, processing integrity, confidentiality or privacy.
- ISO 2000 – certification addresses requirements to plan, implement, establish, operate, monitor, review, maintain and improve an Service Management System.
- HIPAA – Health Insurance Portability and Accountability Act, certification (industry specific) addresses public’s right regarding healthcare coverage, security, and privacy.
- PCI DSS – certified cloud vendors offers security standards for payment account security.
