The best sampling method to use for verifying the adequacy of an organization’s internal controls and being concerned about potential circumvention of regulations is B. Random sampling. Random sampling is a method of selecting a sample from a population in which each item has an equal and independent chance of being selected1. Random sampling reduces the risk of bias or manipulation in the sample selection, and ensures that the sample is representative of the population. Random sampling can be used for both attribute and variable sampling, which are two types of audit sampling that test for the occurrence rate or the monetary value of errors, respectively2.

The primary reason for an IS auditor to perform a risk assessment is to help identify areas with a relatively high probability of material problems. A risk assessment is a systematic process of evaluating the potential risks that may be involved in an activity or undertaking. It involves identifying the sources of risk, analyzing the likelihood and impact of the risk, and prioritizing the risks based on their significance. A risk assessment helps the IS auditor to focus on the areas that are most vulnerable to errors, fraud, or inefficiencies, and to design appropriate audit procedures to address those risks. A risk assessment also helps the IS auditor to allocate audit resources efficiently and effectively.

A risk assessment does not provide a basis for the formulation of corrective action plans, as this is a responsibility of management, not the IS auditor. A risk assessment does not increase awareness of the types of management actions that may be inappropriate, as this is a matter of professional ethicsand judgment. A risk assessment does not help to identify areas that are most sensitive to fraudulent or inaccurate practices, as this is a result of the risk assessment, not its purpose.

 The IS audit manager should specifically review the detailed evidence of the successes and weaknesses of all contingency testing to substantiate the conclusions of the audit of the corporate disaster recovery test. This is because the detailed evidence can provide the audit manager with a clear and objective picture of how well the disaster recovery plan was executed, what issues or gaps were encountered, and what recommendations or actions were taken to address them. The detailed evidence can also help the audit manager to verify the accuracy, completeness, and validity of the audit findings, as well as to evaluate the adequacy and effectiveness of the disaster recovery controls.

The other options are not as specific or relevant as the detailed evidence of all contingency testing. Overviews of interviews between data center personnel and the auditor may provide some useful information, but they are not sufficient to substantiate the conclusions without supporting evidence from the actual testing. Prior audit reports involving other corporate disaster recovery audits may provide some benchmarking or comparison data, but they are not directly related to the current audit scope and objectives. Summary memos reflecting audit opinions regarding noted weaknesses may provide some high-level insights, but they are not enough to substantiate the conclusions without detailed evidence to back them up.

The most important thing to include in security awareness training is how to respond to various types of suspicious activity. Security awareness training is a program that educates employees about the importance of security and how to avoid common threats and risks. One of the main objectives of security awareness training is to enable employees to recognize and report any signs of malicious or unauthorized activity, such as phishing emails, malware infections, data breaches, or social engineering attempts. By teaching employees how to respond to various types of suspicious activity, security awareness training can help to prevent or mitigate the impact of security incidents, protect the organization’s assets and reputation, and comply with legal and regulatory requirements.

The other options are not as important as option A. The importance of complex passwords is a useful topic, but not the most important thing to include in security awareness training. Complex passwords are passwords that are hard to guess or crack by using a combination of letters, numbers, symbols, and cases. Complex passwords can help to protect user accounts and data from unauthorized access, but they are not sufficient to prevent all types of security incidents. Moreover, complex passwords may be difficult to remember or manage by users, and may require additional measures such as password managers or multi-factor authentication. Descriptions of the organization’s security infrastructure is a technical topic, but not the most important thing to include in security awareness training. Security infrastructure is the set of hardware, software, policies, and procedures that provide the foundation for the organization’s security posture and capabilities. Security infrastructure may include firewalls, antivirus software, encryption tools, access control systems, backup systems, etc. Descriptions of the organization’s security infrastructure may be relevant for some employees who are involved in security operations or administration, but they may not be necessary or understandable for all employees who need security awareness training. Contact information for the organization’s security team is a practical detail, but not the most important thing to include in security awareness training. Security team is the group of people who are responsible for planning, implementing, monitoring, and improving the organization’s security strategy and activities. Contact information for the organization’s security team may be useful for employees who need to report or escalate a security issue or request a security service or support. However, contact information for the organization’s security team is not enough to ensure that employees know how to respond to various types of suspicious activity. References: Security Awareness Training | SANS Security Awareness, Security AwarenessTraining | KnowBe4, SecurityAwareness Training Course (ISC)² | Coursera
