The principle of least privilege is the most important principle to apply when granting access to an ERP system that contains a significant amount of personal dat a. The principle of least privilege states that users should only have the minimum level of access and permissions necessary to perform their legitimate tasks and functions, and no more. Applying the principle of least privilege helps to protect the privacy and security of the personal data in the ERP system, as it reduces the risk of unauthorized or inappropriate access, disclosure, modification, or deletion of the data. It also helps to comply with the privacy laws and regulations, such as the GDPR, that require data controllers and processors to implement appropriate technical and organizational measures to ensure a level of security appropriate to the risk.

CDPSE-guided privacy risk management calls for threat analysis/threat modeling to identify current and emerging weaknesses against personal data processing. DLP (C) and communications monitoring (D) are detective measures; reviewing past incidents (A) is retrospective and incomplete. Threat analysis provides forward-looking visibility into vulnerabilities and their impact.
Key CDPSE-aligned phrasing (short extract): "Threat modeling identifies and evaluates privacy threats and vulnerabilities."

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.

Consent is a privacy principle that requires obtaining the permission or agreement of the data subjects before collecting, using, disclosing or transferring their personal data for specific purposes. Consent can be explicit or implicit, depending on the context and nature of the data processing activity and the applicable laws and regulations. An email opt-in form on a website is an example of obtaining explicit consent from the data subjects who voluntarily provide their email address and agree to receive marketing communications from the website owner or operator. The other options are not relevant to an email opt-in form on a website. Accuracy is a privacy principle that requires ensuring that the personal data is correct, complete and up-to-date. Transparency is a privacy principle that requires informing the data subjects about the identity and contact details of the data controller, the purposes and legal bases of the data processing, the rights and choices of the data subjects, and the safeguards and measures to protect the data. Integrity is a privacy principle that requires protecting the personal data from unauthorized or accidental modification, deletion or corruption. , p. 97-98 Reference: : CDPSE Review Manual (Digital Version)

The data subject should contact the organization's chief privacy officer (CPO) first if they believe their personal information has been collected and used without consent. The CPO is the senior executive who is responsible for establishing and maintaining the organization's privacy vision, strategy, and program. The CPO oversees the development and implementation of privacy policies, procedures, standards, and controls, and ensures that they align with the organization's business objectives and legal obligations. The CPO also leads the privacy governance structure, such as the privacy steering committee, and coordinates with other stakeholders, such as the data protection authorities, the privacy rights advocates, and the outside privacy counsel, to ensure that privacy is integrated into all aspects of the organization's operations. The CPO is the primary point of contact for data subjects who have any questions, complaints, or requests regarding their personal information, and who can address their concerns and resolve their issues in a timely and effective manner.
