What is the primary responsibility of a Cloud Service Provider (CSP) after a security breach?

The primary responsibility of a Cloud Service Provider (CSP) after a security breach is to manage tenant resource identity and access control. This involves ensuring that only authorized users have access to sensitive data and resources, which becomes critically important in the aftermath of a breach.

After a security incident, there is a heightened risk that unauthorized individuals may try to exploit vulnerabilities or access compromised accounts. Therefore, it is essential for the CSP to review and reinforce identity and access control mechanisms, ensuring that the right permissions are enforced to limit access based on the principle of least privilege. This includes monitoring current access configurations, revoking any compromised credentials, and implementing stricter authentication measures, such as multi-factor authentication.

The focus on tenant resource identity and access control directly addresses the immediate risks posed by a breach and helps restore trust in the environment by bolstering security around user access to critical assets.
