Who this page is for
IT and security leaders, cloud engineers, architects and anyone making an honest assessment of cloud risk.
What is cloud security?
Cloud security covers all measures that protect identities, configuration, workloads, data and logging in cloud platforms. It extends classic security to the specifics of shared platforms.
Key building blocks
Identity and access: strong identities, MFA, least privilege, clear role models.
Configuration: defaults, baselines and posture management.
Logging: traceable activity at platform, workload and identity level.
Data: classification, encryption, access.
Workloads: hardening, patching, container and serverless security.
Common mistakes
Open storage buckets, overly broad roles, missing MFA on admin accounts, missing or unused logging, stale keys without rotation, unchecked app permissions.
Link to zero trust and Microsoft 365
Cloud security benefits strongly from zero trust principles: continuous verification of identity, device and context. For many organisations Microsoft 365 security is the concrete entry point.
Checklist
- Shared responsibility documented per service
- Strong admin identities with phishing-resistant MFA
- Least privilege on roles and service accounts
- Logging and auditing active and reviewed
- Posture management or regular config review
- Classification and protection of sensitive data
Frequently asked questions
+Are default cloud settings enough?
Rarely. Defaults are a start; responsibility and tuning to your risk remain with you.
+Do I need my own logging in the cloud?
Yes. Platform and identity logs are the foundation for detection and incident response.
