The primary reason for periodic penetration testing of Internet-facing applications is to identify vulnerabilities in the system, because this will help to improve the security and resilience of the applications and the data they process. A penetration test is a simulated cyberattack that aims to exploit the weaknesses and gaps in the security of an application or a system. A penetration test can reveal the vulnerabilities that may not be detected by other methods, such as automated scanning or code review. A penetration test can also measure the impact and severity of the vulnerabilities, as well as the effectiveness of the existing controls and defenses. A penetration test can also provide recommendations and solutions to remediate the vulnerabilities and prevent future attacks. Internet-facing applications are programs and services that are accessible from the internet, such as web applications, APIs, cloud services, or VPN gateways. Internet-facing applications are exposed to a variety of cyber threats, such as denial-of-service attacks, SQL injection attacks, cross-site scripting attacks, or credential stuffing attacks. These threats can compromise the confidentiality, integrity, and availability of the applications and the data they handle. Therefore, periodic penetration testing of Internet- facing applications is essential to identify vulnerabilities in the system and to protect the applications and the data from cyberattacks.

The greatest concern for a risk practitioner when an organization is adopting blockchain for a new financial system is the limited organizational knowledge of the underlying technology. Blockchain is a distributed ledger technology that enables secure and transparent transactions among multiple parties without the need for intermediaries or central authorities. Blockchain technology has many potential benefits for the financial sector, such as reducing costs, increasing efficiency, enhancing security, and improving trust. However, blockchain technology also poses many challenges and risks for the organization, such as technical complexity, interoperability issues, regulatory uncertainty, and cultural resistance. The limited organizational knowledge of the underlying technology is the greatest concern, because it affects the ability and readiness of the organization to adopt, implement, use, and maintain the blockchain system effectively and securely. The limited organizational knowledge could also result in poor decision-making, inadequate governance, insufficient training, and increased vulnerability to errors, fraud, or attacks. The other options are not as concerning as the limited organizational knowledge, although they may also pose some difficulties or limitations for the blockchain adoption. Lack of commercial software support, varying costs related to implementation and maintenance, and slow adoption of the technology across the financial industry are all factors that could affect the feasibility and sustainability of the blockchain system, but they do not directly affect the capability and maturity of the organization.

According to the CRISC Review Manual (Digital Version), the primary reason a risk practitioner would be interested in an internal audit report is to evaluate the maturity of the risk management process, as it provides an independent and objective assessment of the effectiveness and efficiency of the risk management activities and controls. An internal audit report helps to:
Identify and evaluate the strengths and weaknesses of the risk management process and its alignment with the organization's objectives and strategy Detect and report any gaps, errors, or deficiencies in the risk identification, assessment, response, and monitoring processes and controls Recommend and implement corrective actions or improvement measures to address the issues or findings in the risk management process Communicate and coordinate the audit results and recommendations with the relevant stakeholders, such as the risk owners, the senior management, and the board Enhance the accountability and transparency of the risk management process and its outcomes References = CRISC Review Manual (Digital Version), Chapter 4: IT Risk Monitoring and Reporting, Section 4.2: IT Risk Reporting, pp. 223-2241

A possible action that a risk practitioner should do next when an increased industry trend of external cyber attacks is identified is A. Conduct a threat and vulnerability analysis. A threat and vulnerability analysis is a process of identifying and assessing the potential sources and methods of cyber attacks, as well as the weaknesses and gaps in the organization's information systems and security controls12 By conducting a threat and vulnerability analysis, a risk practitioner can determine the level of exposure and risk that the organization faces from external cyber attacks, and prioritize the actions and resources needed to mitigate or prevent them3 A threat and vulnerability analysis can also help to update the risk impact rating and the key risk indicator in the risk register, as well as to notify senior management of the new risk scenario, but these are subsequent steps that follow after the analysis is completed. Therefore, the first action that a risk practitioner should do next is to conduct a threat and vulnerability analysis.
