There is a reason so many businesses are moving to the cloud today, and it’s not just about data storage. Companies are seeing great benefits when leveraging applications in the cloud, although it is important to consider cloud security protocols before making the move. This includes understanding what risks are involved.
The Four Control Levels
Begin by developing a list of cloud security objectives. From IT security in the general sense to accountability, liability, integrity, and confidentiality, understanding these objectives is vital in establishing a cloud security protocol. The Information Systems Audit and Control Association says there are four essential IT resources that are divided into four control levels: applications, infrastructure, information, and people.
The Three Reference Models
These four control levels define general and cloud-specific security. There are also three cloud reference models: Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as a Service (IaaS). With IaaS, the cloud vendor is responsible for the physical or virtual infrastructure. The PaaS model has the cloud provider managing the entire infrastructure, which includes all databases and middleware. With SaaS, the cloud provider offers infrastructure and applications, but the consumer adds the data.
Application and Infrastructure Security
Also important is application and infrastructure security. Responsibility is shared in the SaaS environment. Because the user controls the data and the cloud service provider is in charge of the application, it’s necessary to apply security measures, including secure deployments, protections from threats and manipulation, vulnerability testing, and source code analysis.
You also want to look at security layer infrastructure, which includes measuring endpoint security, network security, physical security, and communication encryption. Again, you have to look at this in terms of reference models. With SaaS, the cloud consumer is in charge of endpoint security. With IaaS, the cloud user is in charge of communication encryption and network security. With PaaS, accountability goes to the provider because they have the appropriate security technologies.
Since cloud security planning is a team effort, it’s important to remember that all the security measures you put toward IT infrastructures are also put toward cloud security. Deciding who controls each component of the cloud infrastructure is crucial because it defines everything about how security measures are applied.
