Which of the following roles is accountable for the confidentiality, integrity, and availability of information within an enterprise?

The data owner is the specific role accountable for the overall confidentiality, integrity, and availability (CIA) of the information they own, making decisions about its classification, access, and usage policies. While other roles contribute, the data owner bears the ultimate responsibility for these aspects.

The lead legal counsel is responsible for legal compliance and advising on legal risks, but not directly for the operational CIA of information assets.

A risk manager identifies and assesses risks, but typically does not hold the ultimate accountability for the CIA of information assets themselves.

A data custodian (or data steward) is responsible for the *implementation* and operational management of controls to protect data, acting on behalf of the data owner, but is not ultimately accountable for the data itself.
