Cloud security concepts are the fundamental principles and practices used to protect data, applications, and infrastructure hosted in cloud computing environments. These concepts address the unique challenges of shared responsibility, dynamic scaling, and distributed access inherent in cloud architectures. They ensure that sensitive information remains confidential, systems are available, and integrity is maintained against cyber threats. For instance, understanding identity and access management (IAM) is crucial for controlling who can access cloud resources and what actions they can perform. A common point of confusion is mistaking cloud security concepts for traditional on-premises security, which often overlooks the shared responsibility model between the cloud provider and the customer. These concepts are vital for certifications like CompTIA Security+, CySA+, and the CISSP exam.
