A DLP solution is specifically designed to monitor, detect, and prevent unauthorized data transfers, including the exfiltration of proprietary information by employees. It can enforce policies to block or alert on attempts to move sensitive data outside the organization's control, whether through email, cloud storage, or external devices. Validating the implementation of a DLP solution provides assurance that mechanisms are in place to prevent and detect data exfiltration.
While reviewing log files, ensuring proper information labeling, and examining the business continuity plan (BCP) are important, a DLP solution directly addresses the risk of data exfiltration by employees.

The use of obsolete encryption algorithms poses the greatest risk because it can fundamentally undermine the security of the PKI, making digital certificates and encrypted communications vulnerable to compromise regardless of how well other controls are implemented.

When an auditor finds that the process owner is accepting residual risk beyond the organization's defined risk appetite, it is not appropriate to accept the action plan or wait until the next committee report.
Escalating to audit management (D) is the correct step. Audit management can then determine whether to escalate further to executive management or the audit committee.
Including in the next report (A) delays timely risk response.
Informing executive management directly (B) bypasses the audit reporting hierarchy.
Accepting the plan (C) would be inappropriate as it ignores risk governance.
