In serverless computing models, the primary security concern is ensuring that secrets (such as API keys, database credentials, etc.) and configuration settings are handled securely. The principle of least privilege means that these secrets and configurations should only beaccessible by the minimum set of functions or services that truly need them, reducing the attack surface. Proper management of secrets and configurations ensures that unauthorized access or misuse is prevented.

Disabling console access completely or using privileged access management is important for securing any environment, but it is not specifically tied to serverless models. Validating the underlying container security is more relevant to containerized environments rather than serverless computing, which abstracts away infrastructure management. Placing serverless components behind application load balancers is useful for routing traffic but is not specifically critical for securing the serverless model itself. Managing secrets and access controls is a more direct concern for securing serverless environments.
