The first step for an IT privacy practitioner following a decision to expand remote working capability is to evaluate the impact resulting from this change on the organization’s privacy policies, programs and practices. This will help identify the risks and gaps that need to be addressed, as well as the opportunities for improvement and optimization. The other options are possible actions that may be taken after the impact assessment, depending on the results and recommendations.

The organization’s potential legal liabilities related to the data should be of greatest concern when an organization wants to store personal data in the cloud, as it may expose the organization to various compliance risks, such as data breach notification laws, data protection regulations, data sovereignty laws, and contractual obligations. The organization should ensure that the cloud storage provider complies with the applicable legal and regulatory requirements, and that the organization retains control and ownership of the data. The organization should also conduct due diligence and risk assessment of the cloud storage provider before entering into a contract. References: 2 Domain 2, Task 9; 4 

A privacy notice is a document that informs data subjects about how their personal data is collected, processed, stored, shared, and protected by an organization. The primary purpose of a privacy notice is to provide transparency to the data subject on the intended use of their personal data, as well as their rights and choices regarding their data. A privacy notice also helps the organization comply with legal and regulatory requirements, such as obtaining consent, demonstrating accountability, and fulfilling the principle of fairness and lawfulness.

The best way to ensure an organization’s enterprise risk management (ERM) framework can protect the organization from privacy harms is to complete a privacy risk assessment. A privacy risk assessment is a systematic process of identifying, analyzing, evaluating, and treating the privacy risks that may affect the organization’s objectives, operations, stakeholders, and reputation. A privacy risk assessment helps to align the ERM framework with the privacy requirements, expectations, and obligations of the organization, as well as to prioritize and mitigate the privacy risks that may cause privacy harms. Privacy harms are the adverse consequences or impacts that may result from the unauthorized or inappropriate use, disclosure, or loss of personal data, such as financial loss, identity theft, discrimination, reputational damage, emotional distress, or physical harm.

The best answer is D. Mutual certificate authentication.

A comprehensive explanation is:

Mutual certificate authentication is a method of mutual authentication that uses public key certificates to verify the identities of both parties in a two-way communication. A public key certificate is a digital document that contains information about the identity of the certificate holder, such as their name, organization, domain name, etc., as well as their public key, which is used for encryption and digital signature. A public key certificate is issued and signed by a trusted authority, called a certificate authority (CA), that vouches for the validity of the certificate.

Mutual certificate authentication works as follows:

Both parties have a public key certificate issued by a CA that they trust.

When they initiate a communication, they exchange their certificates with each other.

They verify the signatures on the certificates using the CA’s public key, which they already have or can obtain from a trusted source.

They check that the certificates are not expired, revoked, or tampered with.

They extract the public keys from the certificates and use them to encrypt and decrypt messages or to generate and verify digital signatures.

They confirm that the identities in the certificates match their expectations and intentions.

By using mutual certificate authentication, both parties can be confident that they are communicating with the intended and legitimate party, and that their communication is secure and confidential.

Mutual certificate authentication is often used in conjunction with Transport Layer Security (TLS), a protocol that provides encryption and authentication for network communications. TLS supports both one-way and two-way authentication. In one-way authentication, only the server presents a certificate to the client, and the client verifies it. In two-way authentication, also known as mutual TLS or mTLS, both the server and the client present certificates to each other, and they both verify them. Mutual TLS is commonly used for secure web services, such as APIs or webhooks, that require both parties to authenticate each other.

Virtual private network (VPN), Secure Shell (SSH), and Transport Layer Security (TLS) are all technologies that can help to ensure the identities of individuals in a two-way communication are verified, but they are not methods of mutual authentication by themselves. They can use mutual certificate authentication as one of their options, but they can also use other methods, such as username and password, pre-shared keys, or tokens. Therefore, they are not as specific or accurate as mutual certificate authentication.

Any organization collecting information about EU residents is required to operate with transparency in collecting and using their personal information. Chapter III of the GDPR defines eight data subject rights that have become foundational for other privacy regulations around the world:

Right to access personal data. Data subjects can access the data collected on them.

One of the privacy requirements related to the rights of data subjects is the right to access, which means that individuals have the right to obtain a copy of their personal data, as well as information about how their data is processed, by whom, for what purposes, and for how long. To meet this requirement, an organization’s technology stack should incorporate features that allow individuals to have direct access to their data, such as self-service portals, dashboards, or applications. This way, individuals can exercise their right to access without relying on intermediaries or manual processes, which can be inefficient, error-prone, or insecure. References: : CDPSE Review Manual (Digital Version), page 137

 Transparency is the most important attribute of a privacy policy because it informs the users about how their personal data is collected, used, shared, and protected by the organization. Transparency also helps to build trust and confidence with the users, and to comply with legal and ethical obligations regarding data privacy.

What is a Privacy Policy? | Privacy Policies

The data owner is the person or entity who has the ultimate authority and responsibility for the protection of personal data collected by an organization. The data owner defines the purpose, scope, classification, and retention of the personal data, as well as the rights and obligations of the data subjects and other parties involved in the data processing. The data owner also ensures that the personal data is handled in compliance with the applicable privacy laws and regulations, as well as the organization’s privacy policies and standards. The data owner may delegate some of the operational tasks to the data processor, data custodian, or data protection officer, but the accountability remains with the data owner.

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: CDPSE Review Manual (Digital Version)

The most important consideration for developing data retention requirements is the applicable regulations that govern the data. Different types of data may be subject to different legal and regulatory obligations, such as how long the data must be kept, how it must be protected, and how it can be accessed or disposed of. Failing to comply with these obligations can result in fines, penalties, lawsuits, or reputational damage for the organization. Therefore, it is essential to identify and follow the applicable regulations for each data category.
