Security Is Part of Cloud Architecture

Security should not be a final checklist after deployment. Identity, data protection, observability, and recovery shape the architecture from the beginning.

Identity is the control plane

Use individual identities, multifactor authentication, role-based permissions, short-lived credentials, and least privilege. Avoid shared administrator accounts and long-lived access keys.

Know where the data lives

Classify sensitive data, encrypt it in transit and at rest, restrict network paths, manage secrets outside source code, and define retention and deletion behavior.

Logging must answer questions

Centralize important activity and application logs so you can determine who changed what, when the event happened, and which systems were affected.

Design for recovery

Backups are only useful when restoration is tested. Define recovery objectives, protect backup access, and document the steps required to restore service.

Patch and improve continuously

Cloud security changes with new dependencies, services, access patterns, and threats. Review permissions, scan dependencies, update systems, and learn from incidents and near misses.
