As a Certified Ethical Hacker, you are assessing a corporation’s serverless cloud architecture.

The Certified Ethical Hacker (CEH) Cloud Computing module emphasizes that serverless environments rely heavily on granular permission models. Attacks involving compromised APIs often succeed because functions are granted excessive privileges.

Option D is correct because enforcing function-level permissions and the principle of least privilege directly limits what a compromised function can execute. CEH documentation states this is the primary defense against serverless abuse.

Option A is beneficial but reactive.

Option B focuses on SaaS governance rather than FaaS execution control.

Option C provides visibility but does not directly prevent privilege misuse.

CEH highlights identity and access management (IAM) as critical in serverless security.
