The best way to ensure the implementation of corrective action plans is to assign accountability to risk owners. Corrective action plans are the plans that describe the actions and resources that are needed to correct or improve the performance or compliance of the processes or controls. Risk owners are the persons who have the authority and responsibility for managing the risks and their responses. By assigning accountability to risk owners, the implementation of corrective action plans can be monitored, evaluated, and enforced, and the results and outcomes can be reported and communicated. The other options are not as effective as assigning accountability to risk owners, as they are related to the training, scheduling, or outsourcing of the corrective action plans, not the oversight or governance of the corrective action plans.

The most effective method for uniquely identifying the originator of electronic transactions is a digital signature. A digital signature is a cryptographic technique that uses a pair of keys, one public and one private, to authenticate the identity and integrity of the sender and the message. A digital signature is created by applying the sender's private key to a hash of the message, and is verified by applying the sender's public key to the signature and comparing it with the hash of the message. A digital signature ensures that the sender cannot deny sending the message (non-repudiation), and that the message has not been altered or tampered with during transmission (data integrity).
