CCSP Experiences a data breach in the cloud Practice Question

An organization experiences a data breach in the cloud. The CSP claims they are not liable because the breach was due to customer misconfiguration. The customer disagrees. What document should be reviewed to determine liability?

⚠ Common exam trap

ISC2 often tests the misconception that a SOC report or privacy policy defines liability, when in fact only the contractual shared responsibility matrix legally allocates responsibility for specific security controls.

Correct answer & explanation

✓

The shared responsibility matrix in the service contract

The shared responsibility matrix (SRM) is the definitive contractual document that delineates which security controls are managed by the cloud service provider (CSP) and which are the customer's obligation. In a breach caused by misconfiguration, the SRM specifies whether the configuration of the affected resource (e.g., an S3 bucket ACL or a security group rule) falls under the customer's responsibility. Without reviewing the SRM, liability cannot be determined because the matrix explicitly maps each control layer (e.g., network, compute, data) to the responsible party.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The CSP's privacy policy
Why it's wrong here
Privacy policies are not typically used for liability determination.
✗
The SOC 2 Type II report from the CSP
Why it's wrong here
SOC 2 describes controls but does not assign liability.
✗
The incident response plan
Why it's wrong here
The IR plan defines response steps, not liability.
✓
The shared responsibility matrix in the service contract
Why this is correct
This matrix explicitly defines responsibilities for security controls.
