What is Cloud computing security?
Cloud computing security refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud hosting. It is an evolving sub-domain of computer security, network security, and, more broadly, information security.
The three most critical cloud computing security issues are related to Data Security, User authentication and Disaster recovery
Data Security – Data Security is a constant concern for organizations storing critical data on a third party server. Ensuring data remains secure is critical for cloud hosting providers to grow their business.
User Authentication – Cloud service providers have to compulsorily ensure that only authorized personnel are provided access to cloud data of users, failing which, the privacy of clients in the cloud hosting environment can be compromised.
Disaster Recovery – Contingency planning and disaster recovery is another area of concern. To cope with any mishappenings, providers backup every instance of data to not one but several bare metals in the cloud hosting data center. More the number of instances, more the reliability. Certain providers have adopted a minimum replications policy, in which, every byte of data is provided with a certain level of redundancy (two or higher) with their cloud hosting plan.
