Understanding the Question:
* The question is about mitigating the impact of social engineering attacks that use AI technology to impersonate senior management personnel.
Analyzing the Options:
* A. Training and awareness of employees for increased vigilance: This is the most proactive approach. Educating employees about the risks and signs of social engineering attacks enhances their ability to recognize and respond appropriately to such threats.
* B. Increased monitoring of executive accounts: Useful but reactive; it doesn't prevent initial attempts.
* C. Subscription to data breach monitoring sites: Helps detect breaches but doesn't directly mitigate impersonation attacks.
* D. Suspension and takedown of malicious domains or accounts: Reactive measure and might not be immediate or comprehensive.
Detailed Explanation:
* Importance of Training: Employees are often the first line of defense against social engineering attacks. Regular training ensures they are aware of the tactics used in such attacks, including those leveraging AI, and how to respond effectively.
* Proactive Measure: Training increases vigilance and the likelihood of early detection, reducing the potential impact of the attack.
* References:
* CRISC Review Manual, Chapter 3: Risk Response and Reporting, discusses the importance of training and awareness programs in mitigating social engineering risks.

Risk treatment options are the actions or plans that are implemented to modify or reduce the risk exposure of the organization. Risk treatment options receive adequate funding when the organization allocates sufficient resources and budget to support the risk response actions, and to ensure that the risk controls are effective and efficient. This is the best evidence that risk management is driving business decisions in the organization, as it shows that the organization prioritizes and values the risk management process, and that it aligns its risk strategy and objectives with its business goals and value creation.

The percentage of unpatched IT assets is a KPI that measures the effectiveness of the IT asset management process in ensuring that the IT assets are updated with the latest security patches and are protected from vulnerabilities. This KPI reflects the compliance of the IT assets with the enterprise's security policy and standards, and the ability of the IT asset management process to identify and remediate any gaps or risks in the IT asset inventory.

The most effective key risk indicator (KRI) for monitoring risk related to a bring your own device (BYOD) program is the number of incidents originating from BYOD devices, as it directly measures the impact and frequency of the potential threats and vulnerabilities associated with the use of personal devices for accessing company data and systems. A BYOD program can pose various risks to an organization, such as data loss or breach, malware infection, unauthorized access, compliance violation, or device theft or loss12. The number of incidents originating from BYOD devices can help to identify and quantify these risks, and to trigger appropriate risk response actions when the incidents exceed the acceptable thresholds. The other options are not the most effective KRIs, as they do not directly measure the risk level or impact of the BYOD program.
The number of users who have signed a BYOD acceptable use policy may indicate the awareness and compliance of the users, but not the actual risk exposure or mitigation. The budget allocated to the BYOD program security controls may indicate the investment and efficiency of the risk management, but not the effectiveness or necessity. The number of devices enrolled in the BYOD program may indicate the scope and scale of the risk, but not the severity or likelihood.

According to the CRISC Review Manual1, access controls are the policies, procedures, practices, and technologies that are designed and implemented to prevent unauthorized or inappropriate access to IT resources and data. Access controls are essential for ensuring the confidentiality, integrity, and availability of data, especially personally identifiable information (Pll), which is any information that can be used to identify, locate, or contact an individual. Insufficient access controls are the greatest concern related to data privacy when implementing an Internet of Things (loT) solution that collects Pll, as they can expose the data to various risks and threats, such as data leakage, theft, loss, corruption, manipulation, or misuse. Insufficient access controls can also cause legal, regulatory, ethical, or reputational issues for the organization, if the data privacy rights and expectations of the individuals are violated or compromised.
