Explanation
The primary consideration of a multinational organization deploying a user and entity behavior analytics (UEBA) tool to centralize the monitoring of anomalous employee behavior is cross-border data transfer, because it may involve the transfer of personal data across different jurisdictions with different privacy laws and regulations. The organization needs to ensure that it complies with the applicable legal requirements and safeguards the privacy rights of its employees when transferring their data to a central location for analysis.
The other options are secondary or operational considerations that may not have a significant impact on the privacy of the employees.

D) Requiring employees to review the organization's privacy policy on an annual basis Short Explanation: Requiring employees to review the organization's privacy policy on an annual basis is the best activity to enable an organization to identify gaps in its privacy posture because it can help to ensure that the employees are aware of the current privacy requirements, expectations, and practices of the organization. It can also help to identify any discrepancies, inconsistencies, or conflicts between the policy and the actual implementation of privacy controls and processes. By reviewing the policy regularly, the organization can also update and improve it as needed to reflect any changes in the privacy landscape, such as new laws, regulations, standards, or threats.

Explanation
The vulnerability that would have the greatest impact on the privacy of information is private key exposure, because it would compromise the encryption and decryption of the information, as well as the authentication and integrity of the communicating parties. A private key is a secret and unique value that is used to encrypt or decrypt data, or to sign or verify digital signatures. If an attacker gains access to the private key, they can read, modify, or impersonate the data or the sender, which would violate the confidentiality, integrity, and authenticity of the information12.

Explanation
Software hardening is a technique that mitigates design flaws in the application development process that may contribute to potential leakage of personal data. Software hardening is a process of modifying or configuring software to make it more secure and resilient against attacks or exploitation. Software hardening can involve various methods, such as removing unnecessary features or functions, disabling debugging or testing modes, applying patches or updates, implementing secure coding practices, etc. Software hardening helps to protect personal data by preventing or reducing the vulnerabilities that can allow unauthorized access, use, disclosure, or transfer of personal data.
