cloudsecurity

Cloud security is the set of policies, controls, and technologies used to protect data, applications, and infrastructure in cloud environments. It covers services across IaaS, PaaS, and SaaS and deployment models such as public, private, hybrid, and multi-cloud. In the shared responsibility model, cloud providers secure the underlying infrastructure while customers are responsible for data protection, access management, and configuration of cloud services.

Key components include identity and access management, data protection and encryption, key management, network security, secure configurations, and continuous monitoring. Cloud security operations rely on threat detection, incident response, vulnerability management, and automation. Tools such as Cloud Security Posture Management, Cloud Workload Protection Platforms, and Cloud Access Security Brokers help enforce policies and protect workloads across environments.

Common threats include misconfigurations, insecure APIs, weak authentication, insider risk, and supply-chain compromises. Best practices emphasize least privilege, multi-factor authentication, zero-trust principles, network segmentation, encryption at rest and in transit, robust key management, regular backups, and tested disaster recovery. Compliance with standards such as ISO 27001 and NIST SP 800-53, and sector-specific rules, is frequently pursued to demonstrate governance and risk management.

Security in the cloud is an ongoing process requiring governance, risk assessment, and continuous monitoring. Organizations should implement formal policies, automate where possible, and regularly audit configurations and access. The landscape includes multi-cloud setups, containerized workloads, and serverless architectures, each with unique security considerations and tooling needs.
