Cloud Security Definition
Cloud security, also known as cloud computing security, covers all the protection of data, applications, and infrastructures involved via cloud computing platforms through security measures. Cloud security means all practices of protecting all elements of cloud computing against cyberattacks. More businesses are now shifting to the cloud for data management, storage and analysis.
This discipline needs to cover technology, protocols, and best practices in cloud environment. Public, private, and hybrid cloud services are the three primary types of cloud environments. Over the last 10 years, the cloud became popular as it provides rapid deployment, flexibility, low up-front costs, and scalability. The most common concern about cloud is security. There are several security issues for cloud computing that are dependent on the cloud deployment model. Cloud Security Alliance (CSA) classified the top threats to cloud computing as abuse and nefarious use of cloud computing; insecure interfaces and APIs, Malicious insiders, shared technology issues, data loss or leakage, account or service hijacking and unknown risk proﬁle.
Data security, identity and access management (IAM), governance, data retention (DR) and business continuity (BC) planning, legal compliance are the main categories of cloud security. So, cloud security should cover the protection of physical networks, data storage, data servers, computer virtualization frameworks, operating systems, middleware, data, applications, and end-user hardware.
