The greatest concern for an IS auditor reviewing an online security awareness program is that metrics have not been established to assess training results. Without metrics, it is difficult to measure the effectiveness of the program and identify areas for improvement. The other findings are also issues that need to be addressed, but they are not as significant as the lack of metrics. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.11

The most importantoutcome of an information security program is to improve the organizational awareness of security responsibilities, as this will foster a culture of security and ensure that all stakeholders are aware of their roles and obligations in protecting the information assets of the organization. An information security program should also aimto achieve other outcomes, such as identifying operating system weaknesses, understanding and accepting emerging security technologies, and reducing the cost to mitigate information security risk, but these are not as important as improving the awareness of security responsibilities, which is the foundation of any effective information security program. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 2402 Planning, "The IS audit and assurance professional should identify and assess risk relevant to the area under review." 1 One of the risk factors to consider is "the level of awareness of management and staff regarding IT risk management" 1. According to the ISACAIT Audit and Assurance Guideline G13 Information Security Management, "The objective of an information security management audit
/assurancereview is to provide management with an independent assessment relating to the effectiveness of information security management within the enterprise." The guideline also states that "the audit/assurance professional should evaluate whether there is an appropriate level of awareness throughout the enterprise regarding information security policies, standards, procedures and guidelines." According to a web search result from Microsoft Security, "Information security programs need to: ... Support the execution of decisions." 2 One of the ways to support the execution of decisions is to ensure that everyone in the organization understands their security responsibilities and follows the security policies and procedures.

When a program release needs to be backed out of production, the changes introduced by that release must be removed from the source code to ensure the system returns to its prior state. This approach ensures that the source code reflects the stable version without the problematic changes.

In a controlled application development environment, the most important segregation of duties should be between the person who implements changes into the production environment and the application programmer. This segregation of duties ensures that no one person can create and deploy code without proper review, testing, and approval. This reduces the risk of errors, fraud, or malicious code being introduced into the production environment.
The other options are not as important as the segregation between the application programmer and the person who implements changes into production, but they are still relevant for achieving a secure and reliable application development environment. The segregation of duties between the person who implements changes into production and the systems programmer is important to prevent unauthorized or untested changes to system software or configuration. The segregation of duties between the person who implements changes into production and the computer operator is important to prevent unauthorized or uncontrolled access to production data or resources. The segregation of duties between the person who implements changes into production and the quality assurance (QA) personnel is important to ensure independent verification and validation of code quality and functionality.
