What is Cloud Security and Why it Matters

Cloud security is the set of tools, policies, and practices that keep your data, applications, and infrastructure safe when they live in the cloud instead of on your own servers.

Cloud security comprises the technologies, practices, and policies that organizations use to protect their resources, services, and infrastructure hosted in the cloud. It is a critical aspect that all enterprises using cloud technology must consider. Notably, cloud security practices differ depending on the type of cloud model used. For instance, in the Infrastructure as a Service (IaaS) model, the cloud provider is responsible for securing the underlying infrastructure while the enterprise looks after the software and systems in the cloud. Most organizations use the cloud to store and access their valuable data and critical applications.

As a result, there is a high likelihood that cybercriminals might target these resources. Poor cloud security practices can also make it easy for these criminals to access the enterprise’s data, systems, and services. Therefore, it is essential for organizations to understand the shared responsibility model associated with cloud security. For instance, the cloud provider is responsible for securing the hardware while the enterprise looks after other aspects such as access control and encryption.

Shared Responsibility at a Glance
