A business is expanding to a new country and must protect customers from accidental disclosure of specific national identity information. Which of the following should the security engineer update to best meet business requirements?

Security Information and Event Management (SIEM) systems focus on aggregating and analyzing security event logs from various sources to detect and respond to threats. While SIEM can help in identifying potential security incidents, it does not specifically prevent the unauthorized disclosure of sensitive information. Therefore, it is not the best choice for directly addressing the issue of protecting national identity data.

The Security Content Automation Protocol (SCAP) is a framework for automating security compliance and vulnerability management. While SCAP can aid in ensuring systems are configured securely, it does not provide mechanisms for monitoring or preventing the unauthorized sharing of sensitive information. Thus, it does not directly meet the requirement of protecting customer identity information.

A Web Application Firewall (WAF) serves to protect web applications by filtering and monitoring HTTP traffic between a web application and the internet. While it can help prevent certain types of attacks, it does not specifically target the protection of sensitive identity information from accidental disclosure. Therefore, it is less relevant in this context.
