Cloud security refers to a set of policies and technologies designed to protect data, applications, and services stored in the cloud. It encompasses strategies to safeguard against unauthorized access, data breaches, and various cyber threats. Organizations leverage encryption, identity management, and continuous monitoring to ensure compliance with regulations and maintain data integrity. Proper cloud security also involves understanding shared responsibility where both service providers and customers must implement adequate protective measures. As cloud adoption increases, effective cloud security measures become essential to mitigate risks.
