Cloud Security Fundamentals cover

Cloud platforms are not less secure than data centres, but they fail differently. Almost every incident traces back to identity, configuration or missing visibility.

Identity is the new perimeter

Over-permissive roles are the most common finding in cloud reviews. Least privilege is tedious to implement and consistently worth the effort.

Configuration drift is inevitable

Environments change faster than documentation. Automated posture checks catch the storage bucket someone opened for a quick test and forgot to close.

  • Baseline every account
  • Alert on public exposure changes
  • Review privileged roles monthly

Logging must be on before you need it

Audit logs are cheap to enable and impossible to recover retroactively. Turn them on for every account on day one and forward them somewhere durable.
