Cloud Security Best Practices for AWS, Azure & GCP

### Key Cloud Security Hardening Principles With over 90% of organizations operating in hybrid or multi-cloud environments, cloud misconfigurations remain the leading cause of massive data leaks. #### 1. Enforce Strict IAM & Principle of Least Privilege Never use root accounts for daily workloads. Enforce phishing-resistant Multi-Factor Authentication (MFA) and granular role-based access control (RBAC). #### 2. Encrypt All Data at Rest and in Transit Utilize customer-managed encryption keys (KMS) with automated rotation policies. Enforce TLS 1.3 across all public and internal service meshes. #### 3. Implement Cloud Security Posture Management (CSPM) Continuously scan cloud infrastructure for open S3 buckets, permissive security groups, and unencrypted databases.
