Audit and accountability control are critical components of an organization's information system security. They help in identifying and mitigating risks by providing evidence of the system's activities, identifying security breaches, and enabling the organization to take corrective actions. The three functions of audit and accountability control are as follows:

1. Implement an effective audit program: An audit program is a systematic approach to evaluate the effectiveness of an organization's security controls. It involves assessing the organization's security posture, identifying security gaps, and recommending remedial actions. An effective audit program helps in ensuring that the organization's security controls are functioning as intended and meeting the desired objectives.

2. Implement effective access control: Access control is the process of restricting access to information systems, data, and other resources. Effective access control helps in ensuring that only authorized personnel can access sensitive information or perform critical functions. Access control is an essential element of audit and accountability control, as it helps in preventing unauthorized access and ensuring the integrity, confidentiality, and availability of information.

3. Provides details on how to determine what to audit: Audit logs contain a record of system activities, including user activity, system changes, and other relevant information. An effective audit and accountability control should define what activities are to be audited, when, and how. Determining what to audit helps in identifying security incidents, detecting anomalies, and monitoring compliance with policies, regulations, and laws.

In summary, audit and accountability control are essential components of an organization's information security. An effective audit program, access control, and determining what to audit help in ensuring that the organization's security controls are functioning as intended and meeting the desired objectives.
