Domain accounts are configured to lock out based on predefined access policies, reducing the effectiveness of brute-force attacks on authentication mechanisms. The platform employs IAM roles for identification and authentication within its cloud infrastructure that govern user access to resources and manage provisioning, deployment, and configuration within the platform environment. This reduces the risk of unauthorized access through third-party or external user accounts. Finally, memory protection mechanisms are used to enhance resilience against unauthorized commands or improper authentication.",
