Cloud computing security refers to the set of practices, policies, and technologies that are implemented to protect data, applications, and infrastructure in cloud environments. As the use of cloud computing continues to grow, it becomes crucial to ensure the confidentiality, integrity, and availability of data stored or transmitted over the internet. Cloud computing security encompasses various measures, including access control, encryption, data loss prevention, and network security, among others. These measures are employed by cloud service providers to safeguard against threats such as unauthorized access, data breaches, and malware attacks. By leveraging robust security mechanisms, cloud computing users can trust that their data and applications are adequately protected in the cloud.
