Data loss prevention (DLP) tools are technologies that help to prevent unauthorized access, use, or transfer of personal data. DLP tools can monitor, detect, and block data leakage or exfiltration from various sources, such as endpoints, networks, cloud services, or email. DLP tools can also enforce data protection policies and compliance requirements, such as encryption, masking, or deletion of sensitive data. DLP tools can help to protect personal data from both internal and external threats, such as malicious insiders, hackers, or accidental exposure.

The organization should disclose the relationship to those affected in jurisdictions where such disclosures are required, as this is the most appropriate and compliant action to take after identifying a privacy risk related to third-party data collection. Disclosing the relationship to the data subjects is a way of providing transparency and accountability, as well as respecting their rights and choices regarding their personal data. It also helps the organization avoid regulatory fines or sanctions for not complying with the applicable privacy laws or regulations that mandate such disclosures. The other options are not as effective or sufficient as disclosing the relationship, as they do not address the root cause of the risk, do not mitigate the potential harm to the data subjects, or do not align with the privacy principles and best practices.

A mobile application implementation should meet the organization’s data security standards by ensuring that the application does not contain any vulnerabilities, errors or malicious code that could compromise the confidentiality, integrity or availability of the data. An automatic dynamic code scan is a technique that analyzes the application code while it is running to detect and report any security issues or defects. An automatic dynamic code scan can help to identify and fix any potential data security risks before the application is deployed. The other options are not sufficient to ensure data security standards. UAT is a process of verifying that the application meets the user requirements and expectations, but it does not necessarily test for data security. Data classification is a process of categorizing data according to its sensitivity and value, but it does not ensure that the data is protected by the application. A PIA is a process of identifying and evaluating the privacy impacts of a system or project that involves personal data, but it does not ensure that the system or project meets data security standards. , p. 89-90 References: : CDPSE Review Manual (Digital Version)

The best approach for a local office of a global organization faced with multiple privacy-related compliance requirements is to focus on the requirements with the highest organizational impact, because this will help prioritize the most critical and urgent privacy issues and risks that may affect the organization’s reputation, operations, or legal obligations. Focusing on the highest impact requirements will also help allocate the resources and efforts more efficiently and effectively, as well as align the local office’s privacy practices with the global organization’s objectives and strategies12.

A private cloud is a cloud deployment model that provides exclusive access and control to a single organization or a specific group of users within the organization. A private cloud is best for an organization whose main objectives are to logically isolate personal data from other tenants and adopt custom privacy controls for the data, as it offers the highest level of security, privacy, and customization among the cloud deployment models. A private cloud allows the organization to implement its own privacy policies, standards, and procedures for the personal data, as well as to configure the cloud infrastructure, services, and applications according to its specific needs and preferences. A private cloud also reduces the risk of data breaches, unauthorized access, or co-mingling of data from other tenants, as the personal data is stored and processed in a dedicated and isolated environment.

API keys are codes that are used to identify and authenticate an application or user when accessing an API. API keys could be stored insecurely, such as in plain text, in public repositories, or in unencrypted files. This could expose the API keys to unauthorized access, theft, or misuse by malicious actors, who could then access the API and the data it contains. This could result in data breaches, privacy violations, fraud, or other damages.

The best testing method to identify and review the application’s runtime modules is dynamic application security testing (DAST). DAST is a testing technique that analyzes the application’s behavior and functionality during its execution. DAST can detect security and privacy vulnerabilities that are not visible in the source code, such as injection attacks, cross-site scripting, broken authentication, sensitive data exposure, or improper error handling. DAST can also simulate real-world attacks and test the application’s response and resilience. DAST can provide a comprehensive and realistic assessment of the application’s security and privacy posture in the pre-production environment. References:

Automated data discovery and classification tools provide continuous and systematic identification of data assets across the enterprise, ensuring accuracy and reducing manual errors. Internal updates (B) and departmental reporting (D) depend on human diligence; periodic manual audits (C) are time-bound and may miss changes between reviews.

“Automated discovery ensures a current and reliable data inventory, critical for privacy compliance.”

Input validation controls are the best way to ensure consumer credit card numbers are accurately captured. Input validation controls are methods that check the format, type, range, and length of the input data before accepting, processing, or storing it. Input validation controls can help prevent errors, fraud, or data loss by rejecting invalid, incomplete, or malicious input. For example, input validation controls can verify that a credit card number follows the Luhn algorithm1, has the correct number of digits2, and matches the card issuer’s prefix3. Input validation controls can also prevent SQL injection attacks4 or cross-site scripting attacks5 that may compromise the security and privacy of the data.

Input reference controls, access controls, and reconciliation controls are also important for data quality and security, but they do not directly ensure the accuracy of consumer credit card numbers. Input reference controls are methods that compare the input data with a predefined list of values or a reference table to ensure consistency and validity. For example, input reference controls can check if a country name or a postal code is valid by looking up a database of valid values. Access controls are methods that restrict who can access, modify, or delete the data based on their roles, permissions, or credentials. For example, access controls can prevent unauthorized users from accessing or tampering with consumer credit card numbers. Reconciliation controls are methods that compare the data from different sources or systems to ensure completeness and accuracy. For example, reconciliation controls can check if the transactions recorded in the accounting system match the transactions processed by the payment gateway.
