Comment surveiller et appliquer les règles de sécurité du cloud avec CASB pour Google Cloud ?

Utilize a Cloud Access Security Broker (CASB) for Google Cloud to monitor and enforce security policies. This involves real-time visibility, threat detection, and policy enforcement to ensure compliance and data protection.

Using a CASB (Cloud Access Security Broker) for Google Cloud is critical to ensuring a robust security posture. In my experience as an ethical hacker and cybersecurity professional, I’ve seen how a CASB provides visibility and control that is often lacking in traditional cloud security approaches. For instance, during a security audit for a client in the financial sector, we identified significant data leakage risks due to shadow IT practices. By implementing a CASB solution, we were able to monitor and classify cloud data in real-time, enforce encryption policies, and apply granular access controls. This not only mitigated data leakage risks but also ensured compliance with stringent financial regulations.
