A buffer overflow is a software coding error or vulnerability that occurs when a function is carried out with more data than the function can handle, resulting in adjacent memory locations being overwritten or corrupted by the excess data1. A program contains a hidden and unintended function that presents a security risk is not a buffer overflow, but rather a backdoor2. Malicious code designed to interfere with normal operations is not a buffer overflow, but rather malware3. A type of covert channel that captures data is not a buffer overflow, but rather a keylogger.

= Initiating the organization’s incident response process is the best course of action for the information security manager when a cloud application used by the organization is found to have a serious vulnerability. The incident response process is a set of predefined steps and procedures that aim to contain, analyze, resolve, and learn from security incidents. The information security manager should follow the incident response process to ensure that the vulnerability is properly reported, assessed, mitigated, and communicated to the relevant stakeholders. The incident response process should also involve the cloud service provider (CSP) and the business owner of the application, as they are responsible for the security and functionality of the cloud application. Instructing the vendor to conduct penetration testing, suspending the connection to the application in the firewall, and reporting the situation to the business owner of the application are all possible actions that may be taken as part of the incident response process, but they are not the best initial course of action. Penetration testing may help to identify the root cause and the impact of the vulnerability, but it may also cause further damage or disruption to the cloud application. Suspending the connection to the application in the firewall may prevent unauthorized access or exploitation of the vulnerability, but it may also affect the availability and continuity of the cloud application. Reporting the situation to the business owner of the application is an important step to inform them of the risk and the potential business impact, but it is not sufficient to address the vulnerability and its consequences. Therefore, the information security manager should initiate the incident response process as the best course of action, and then perform the other actions as appropriate based on the incident response plan and the risk assessment. References = CISM Review Manual 2023, page 211 1; CISM Practice Quiz 2

The most important issue in a penetration test is having a defined goal as well as success and failure criteria. A penetration test is a simulated cyber attack against a computer system or an application to check for exploitable vulnerabilities. The goal of a penetration test is to identify and evaluate the security risks and weaknesses of the target system or application, and to provide recommendations for improvement. The success and failure criteria of a penetration test are the metrics and indicators that measure the effectiveness and efficiency of the test, and the extent to which the test achieves its goal. By having a defined goal as well as success and failure criteria, the penetration tester can plan and execute the test in a systematic and structured manner, and can communicate and report the results and findings in a clear and concise way. The other options are not the most important issue in a penetration test, although they may be some factors or considerations that affect the test. Having an independent group perform the test is a desirable practice, as it can provide an unbiased and objective assessment of the target system or application. However, it is not essential, as long as the penetration tester follows ethical hacking principles and standards. Obtaining permission from audit is a mandatory requirement, as it ensures that the penetration test is authorized and compliant with the organization’s policies and regulations. However, it is not an issue, as it is a prerequisite for conducting the test. Performing the test without the benefit of any insider knowledge is an optional approach, as it simulates a real-world attack by an external hacker who does not have access to the internal design or configuration of the target system or application. However, it is not always feasible or effective, as some vulnerabilities may be hidden or inaccessible from an outsider’s perspective.
