Securing multi cloud environments is no small feat. Default security controls often fall short, and what works for one of the major CSPs—AWS, Azure, or Google Cloud—might not work for the others. Instead of focusing solely on assent, organizations should adopt attack-driven controls to protect their most critical cloud assets.

Recognizing that application flaws are unavoidable—whether in-house or third-party—is crucial for building effective cloud security controls. While fixing vulnerable code may not always be feasible, applying secure cloud configurations often provides a more practical solution. Relying on CSP defaults and documentation isn’t enough, as they often include errors, omissions, or conflicting information. In cases like zero-day vulnerabilities in cloud services, organizations must focus on controlling what’s within their power to mitigate potential damage.

Tools like the Cloud Matrix, Cloud Provider Benchmarks, and the Cyber Defense Matrix are helpful, but they have their limitations. That’s why this course goes a step further, offering actionable techniques to safeguard what matters most to your organization. By addressing common cloud misconfigurations and implementing effective security controls, you can shrink your attack surface and fortify your cloud environment.
