Explanation
Compartmentalizing resource access is a security technique that divides a system or network into separate segments or zones with different levels of access and control, based on the sensitivity and value of the data or resources. Compartmentalizing resource access would most effectively reduce the impact of a successful breach through a remote access solution, as it would limit the scope and extent of the breach, and prevent unauthorized access to other segments or zones that contain more critical or sensitive data or resources. The other options are not as effective as compartmentalizing resource access in reducing the impact of a successful breach through a remote access solution. Regular testing of system backups is a security technique that verifies the availability and recoverability of data in case of a system failure or disaster, but it does not prevent or limit unauthorized access to data. Monitoring and reviewing remote access logs is a security technique that records and analyzes the activities and events related to remote access sessions, but it does not prevent or limit unauthorized access to data. Regular physical and remote testing of the incident response plan is a security technique that evaluates and improves the readiness and effectiveness of an organization's response to security incidents, but it does not prevent or limit unauthorized access to data1, p. 91-92 References: 1: CDPSE Review Manual (Digital Version)

Explanation
Obtaining user consent is the best way to mitigate the privacy risk associated with setting cookies on a website. This means that the website should inform the users about the purpose, type, and duration of the cookies, and ask for their permission before storing or accessing any cookies on their browsers. This way, the users can exercise their right to control their personal data and opt-in or opt-out of cookies as they wish.
According to the General Data Protection Regulation (GDPR), consent must be freely given, specific, informed, and unambiguous. The website should provide clear and easy-to-understand information about the cookies and their implications for the users' privacy, and offer a simple and effective way for the users to indicate their consent or refusal. The website should also respect the users' choice and allow them to withdraw their consent at any time.
Implementing impersonation, ensuring nonrepudiation, and applying data masking are not relevant or effective methods to mitigate the privacy risk associated with setting cookies on a website. Impersonation means accessing or using data on behalf of another user, which could violate their privacy and security.
Nonrepudiation means providing proof of the origin, authenticity, and integrity of data, which does not address the issue of user consent or preference. Data masking means hiding or replacing sensitive data with fake or modified data, which does not prevent the storage or access of cookies on the user's browser.

Explanation
Anonymization is a technique that removes or modifies all identifiers in a data set to prevent or limit the identification of the data subjects. Anonymization is the IT privacy practitioner's best recommendation for an organization that uses analytics derived from archived transaction data to create individual customer profiles for customizing product and service offerings, as it would protect the privacy of the customers by reducing the linkability of the data set with their original identity, and also comply with the data minimization principle that requires limiting the collection, storage and processing of personal data to what is necessary and relevant for the intended purposes. Anonymization would also preserve some characteristics or patterns of the original data that can be used for analysis or customization purposes, without compromising the accuracy or quality of the results. The other options are not as effective as anonymization in this situation. Discontinuing the creation of profiles is not a feasible or desirable option, as it would prevent the organization from achieving its business objectives and providing value to its customers. Implementing strong access controls is a security measure that restricts who can access, view or modify the data, but it does not address the issue of collecting or retaining more personal data than necessary or relevant. Encrypting data at rest is a security measure that transforms plain text data into cipher text using an algorithm and a key, making it unreadable by unauthorized parties, but it does not address the issue of collecting or retaining more personal data than necessary or relevant, and may require additional security measures to protect the encryption keys or certificates1, p. 75-76 References: 1:

Explanation
The best time during the secure development life cycle to perform privacy threat modeling is early in the design phase, because this will help identify and mitigate the potential privacy risks and vulnerabilities of the system or application before they become costly or difficult to fix. Privacy threat modeling is a systematic process of analyzing the data flows, assets, actors, and scenarios of a system or application to identify and prioritize the privacy threats and countermeasures12. Performing privacy threat modeling early in the design phase will also help ensure that privacy is built into the system or application from the start, rather than as an afterthought.

Explanation
The best way to validate compliance with agreed-upon service levels established with a third party that processes personal data is to have a contractual right to audit, which means that the organization can conduct audits or inspections of the third party's privacy practices, policies, and procedures to verify that they meet the contractual obligations and expectations. A contractual right to audit can also help identify and address any privacy risks or gaps that may arise from the third party's processing of personal data12.
