Some organizations, typically those that manage large amounts of personal information related to employees, customers, or constituents, will employ a chief privacy officer (CPO). Some organizations have a CPO because applicable regulations such as the Gramm-Leach-Bliley Act (GLBA) require it. Other regulations such as the Health Information Portability and Accountability Act (HIPAA), the Fair Credit Reporting Act (FCRA), and the GLBA place a slate of responsibilities upon an organization that compels them to hire an executive responsible for overseeing compliance.

The chief privacy officer (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 chief data officer (CDO), the information security steering committee, and the legal counsel, to ensure that privacy is integrated into all aspects of the organization's operations.Reference:: CDPSE Review Manual (Digital Version), page 21

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.

Conducting a privacy impact assessment (PIA) should be done first to establish privacy by design when developing a contact-tracing application. A PIA is a systematic process that identifies and evaluates the potential effects of personal data processing operations on the privacy of individuals and the organization. A PIA helps to identify privacy risks and mitigation strategies at an early stage of development and ensures compliance with legal and regulatory requirements. Conducting a development environment review, identifying privacy controls, or identifying differential privacy techniques are important steps in privacy by design, but they should be done after conducting a PIA.Reference:CDPSE Exam Content Outline, Domain 2, Task 2.1

However, the risks associated with long-term retention have compelled organizations to consider alternatives; one is data archival, the process of preparing data for long-term storage. When organizations are bound by specific laws to retain data for many years, archival provides a viable opportunity to remove data from online transaction systems to other systems or media.

Data archiving is the process of moving data that is no longer actively used to a separate storage device for long-term retention. Data archiving helps to reduce the cost and complexity of data storage, improve the performance and availability of data systems, and comply with data retention policies and regulations. Data archiving should document controls relating to periods of retention for personal data, such as the criteria for determining the retention period, the procedures for deleting or anonymizing data after the retention period expires, and the mechanisms for ensuring the integrity and security of archived data.Reference:: CDPSE Review Manual (Digital Version), page 123

One of the most common vulnerabilities that can compromise the access to personal information is end users using weak passwords. Weak passwords are passwords that are easy to guess, crack, or steal, such as passwords that are short, simple, common, or reused. Weak passwords can allow unauthorized or malicious parties to gain access to personal information and cause privacy breaches, leaks, or misuse. Multi-factor authentication is an effective way to mitigate this vulnerability, as it requires end users to provide more than one piece of evidence to verify their identity, such as something they know (e.g., password), something they have (e.g., token), or something they are (e.g., biometric). Multi-factor authentication makes it harder for attackers to bypass the authentication process and access personal information.Reference:: CDPSE Review Manual (Digital Version), page 107
