Cloud Security refers to a comprehensive set of practices, technologies, and policies designed to protect cloud-based systems, data, and infrastructure from cyber threats. As businesses increasingly rely on cloud computing—whether through public, private, or hybrid clouds—the need for robust cloud security becomes critical. Unlike traditional IT environments, cloud computing introduces unique risks due to its distributed nature, shared resources, and reliance on third-party service providers.

A core concept in cloud security is the shared responsibility model, where cloud providers manage the security of the cloud infrastructure (e.g., hardware, storage, and networking), while customers are responsible for securing their data, applications, and user access. This model makes it essential for organizations to clearly understand and manage their part of the security stack.

Cloud security encompasses several critical domains:

• Identity and Access Management (IAM) to control user permissions and authentication.
• Data protection, including encryption at rest and in transit.
• Threat detection through monitoring and logging services.
• Compliance enforcement, ensuring alignment with standards like GDPR, HIPAA, and ISO 27001.
• Configuration management, addressing misconfigured assets—a leading cause of cloud breaches.

Leading cloud providers such as AWS, Azure, and Google Cloud offer native security tools, but organizations often supplement these with third-party solutions for greater visibility, threat intelligence, and automation. Best practices include implementing Zero Trust architectures, using Multi-Factor Authentication (MFA), conducting regular security assessments, and enforcing least privilege access.

As cloud adoption accelerates, so do the threats targeting these environments. A strong cloud security strategy not only protects sensitive information and workloads but also builds trust with customers and regulators, helping organizations innovate confidently in the cloud.
