Summary

Cloud platforms such as AWS, Azure, and GCP are attractive to enterprises, but require independent security measures. The Shared Responsibility Model clarifies that cloud providers cannot guarantee complete security. Companies must review and secure their configurations themselves. Automated tools like ScoutSuite and Prowler help systematically identify vulnerabilities and monitor them regularly.

Detailed Summary

Many companies outsource their IT systems to cloud environments to save resources and benefit from professional expertise. However, there is a common misconception: cloud providers are not solely responsible for security.

The Shared Responsibility Model clearly defines that providers (such as AWS, Azure, or GCP) secure the infrastructure, while companies are independently responsible for their own components and configurations. Security-by-Default is not guaranteed – many cloud features must be configured manually.

Independent audits are therefore indispensable. Companies must ensure that their cloud configurations meet security requirements – at least at the same level as internal systems, or even higher if in doubt.

Automated testing tools play a central role: ScoutSuite is suitable for smaller environments and initial audits, while Prowler supports complex multi-cloud setups and regular assessments.

Key Messages

  • Shared Responsibility means: cloud providers and customers share security responsibility
  • Cloud systems do not automatically follow the Security-by-Default principle
  • Companies must independently review and secure their configurations
  • Automation is essential for continuous monitoring
  • ScoutSuite and Prowler are proven testing tools for different environment sizes

Action Relevance

Decision-makers should:

  • Define a clear Shared Responsibility Model for their organization
  • Implement automated testing tools (ScoutSuite/Prowler)
  • Schedule regular security audits – not as a one-time activity
  • Set security requirements for cloud systems at least as high as for internal infrastructure
  • Build or hire trained personnel for cloud security
