The most important factor to ensure when developing an effective security awareness program is B. Outcome metrics for the program are established. This is because outcome metrics are measures that evaluate the impact and results of the security awareness program on the behavior and performance of the users, and the security posture and objectives of the organization1. Outcome metrics can help ensure the effectiveness of the security awareness program by:
Providing feedback and evidence on whether the security awareness program is achieving its goals and expectations, such as reducing the number of incidents, improving the compliance rate, or increasing the reporting rate1.
Identifying and quantifying the strengths and weaknesses of the security awareness program, and enabling continuous improvement and optimization of the program content, delivery, and frequency1.
Demonstrating and communicating the value and return on investment of the security awareness program to the stakeholders and management, and securing their support and commitment for the program1.

File transfer protocol (FTP) is a service that allows users to transfer files between computers over a network.
If enabled within firewall rules, FTP would present the greatest risk, as it can expose sensitive data to unauthorized access, modification, or deletion. FTP does not provide encryption or authentication, which makes it vulnerable to eavesdropping, spoofing, and tampering attacks. Simple mail transfer protocol (SMTP), simple object access protocol (SOAP), and hypertext transfer protocol (HTTP) are also services that can be used to exchange data over a network, but they have more security features than FTP, such as encryption, authentication, or validation.

Assessing and tracking all compliance audit findings is the best way to support the effectiveness of a compliance program. This allows an organization to identify areas of non-compliance, take corrective action, and monitor improvements over time12. While implementing an awareness plan, using a governance, risk, and compliance (GRC) tool, and monitoring applicable regulations can contribute to a compliance program, they do not provide the same level of continuous improvement and effectiveness as assessing and tracking audit findings.
