Acknowledgement and attestation involve formal confirmation that an application is no longer in scope for compliance, auditing, or reporting requirements. This typically includes documentation signed by relevant stakeholders confirming that the software no longer processes, stores, or transmits relevant data.
* Data inventory and retention (A) is related to managing data assets, not software scope confirmation.
* Right to be forgotten (B) pertains to privacy laws (e.g., GDPR), allowing individuals to request data deletion.
* Due care and due diligence (C) focus on security best practices rather than software applicability.

Theprimary goal of corrective controls in financial systems is to ensure that errors do not propagate across interconnected systems. Financial transactions are ofteninterdependent, meaning one incorrect or unauthorized change can affect multiple systems. Regulations often mandate these controls tomaintain accuracy and prevent cascading failures.
* A (insider threats altering banking details)is a concern, but thisscenario focuses on corrective controls, not insider threats specifically.
* C (business insurance)is unrelated to why corrective controls are implemented.
* D (preventing unauthorized changes)falls underpreventive, notcorrectivecontrols.

Smishing is a type of social engineering technique that uses text messages (SMS) to trick victims into revealing sensitive information, clicking malicious links, or downloading malware. Smishing messages often appear to come from legitimate sources, such as banks, government agencies, or service providers, and use urgent or threatening language to persuade the recipients to take action12. In this scenario, the text message that claims to be from the payroll department is an example of smishing.
Impersonation is a type of social engineering technique that involves pretending to be someone else, such as an authority figure, a trusted person, or a colleague, to gain the trust or cooperation of the target. Impersonation can be done through various channels, such as phone calls, emails, text messages, or in-person visits, and can be used to obtain information, access, or money from the victim34. In this scenario, the text message that pretends to be from the payroll department is an example of impersonation.
A . Typosquatting is a type of cyberattack that involves registering domain names that are similar to popular or well-known websites, but with intentional spelling errors or different extensions. Typosquatting aims to exploit the common mistakes that users make when typing web addresses, and redirect them to malicious or fraudulent sites that may steal their information, install malware, or display ads56. Typosquatting is not related to text messages or credential verification.
B . Phishing is a type of social engineering technique that uses fraudulent emails to trick recipients into revealing sensitive information, clicking malicious links, or downloading malware. Phishing emails often mimic the appearance and tone of legitimate organizations, such as banks, retailers, or service providers, and use deceptive or urgent language to persuade the recipients to take action78. Phishing is not related to text messages or credential verification.
D . Vishing is a type of social engineering technique that uses voice calls to trick victims into revealing sensitive information, such as passwords, credit card numbers, or bank account details. Vishing calls often appear to come from legitimate sources, such as law enforcement, government agencies, or technical support, and use scare tactics or false promises to persuade the recipients to comply9 . Vishing is not related to text messages or credential verification.
F . Misinformation is a type of social engineering technique that involves spreading false or misleading information to influence the beliefs, opinions, or actions of the target. Misinformation can be used to manipulate public perception, create confusion, damage reputation, or promote an agenda . Misinformation is not related to text messages or credential verification.

The vulnerability should be documented in the risk register because it represents an identified risk that cannot be immediately remediated. A risk register tracks risk details such as description, owner, likelihood, impact, severity, mitigation strategy, acceptance status, review dates, and residual risk. Since the developers cannot patch the issue for six months, the organization needs formal visibility and accountability until remediation is possible. A patching schedule may track when updates are planned, but it does not fully document risk ownership and business impact. A vulnerability matrix may help prioritize technical findings, but it is not the central governance record. Change management procedures control changes, not long-term risk tracking.
