The most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database is data link encryption. Data link encryption is a type of encryption or a protection technique or mechanism that encrypts or protects the data or the information that is transmitted or communicated over the data link layer or the second layer of the Open Systems Interconnection (OSI) model, which is the layer or the level that provides or offers the reliable or the error-free transmission or communication of the data or the information between the nodes or the devices that are connected or linked by the physical layer or the first layer of the OSI model, such as the switches, the bridges, or the wireless access points. Data link encryption can provide a high level of security or protection for the data or the information that is transmitted or communicated over the data link layer, as it can prevent or reduce the risk of unauthorized or inappropriate access, disclosure, modification, or interception of the data or the information by the third parties or the attackers who capture or monitor the data or the information over the data link layer, and as it can also provide the confidentiality, the integrity, or the authenticity of the data or the information that is transmitted or communicated over the data link layer. Data link encryption is the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, as it can ensure or maintain the security or the quality of the sensitive customer data or the information that is transmitted or communicated over the data link layer, by encrypting or protecting the sensitive customer data or the information that is going to be added to the database, and by preventing or reducing the risk of unauthorized or inappropriate access, disclosure, modification, or interception of the sensitive customer data or the information by the third parties or the attackers who capture or monitor the sensitive customer data or the information over the data link layer.
A. Discretionary Access Control (DAC) procedures are not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, but rather a type of access control or a protection mechanism or process that grants or denies the access or the permission to the resources or the data within a system or a service, based on the discretion or the decision of the owner or the creator of the resources or the data within the system or the service, such as the user, the device, or the process. Discretionary Access Control (DAC) procedures can provide a low level of security or protection for the system or the service, as it can increase or enhance the risk of unauthorized or inappropriate access or permission to the resources or the data within the system or the service, by the user or the device that is not approved or authorized by the owner or the creator of the resources or the data within the system or the service, such as the user, the device, or the process, and as it can also depend or rely on the trust or the confidence of the owner or the creator of the resources or the data within the system or the service, such as the user, the device, or the process, for the access control or the protection mechanism or process. Discretionary Access Control (DAC) procedures are not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, as they do not provide or offer the encryption or the protection for the sensitive customer data or the information that is transmitted or communicated over the data link layer, and as they do not prevent or reduce the risk of unauthorized or inappropriate access, disclosure, modification, or interception of the sensitive customer data or the information by the third parties or the attackers who capture or monitor the sensitive customer data or the information over the data link layer.
B. Mandatory Access Control (MAC) procedures are not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, but rather a type of access control or a protection mechanism or process that grants or denies the access or the permission to the resources or the data within a system or a service, based on the sensitivity or the classification of the resources or the data within the system or the service, such as the public, the confidential, or the secret, and the clearance or the authorization of the user or the device that accesses or handles the resources or the data within the system or the service, such as the low, the medium, or the high. Mandatory Access Control (MAC) procedures can provide a high level of security or protection for the system or the service, as it can prevent or reduce the risk of unauthorized or inappropriate access or permission to the resources or the data within the system or the service, by the user or the device that does not have the appropriate or the necessary clearance or authorization to access or to handle the resources or the data within the system or the service, based on the sensitivity or the classification of the resources or the data within the system or the service, such as the public, the confidential, or the secret. However, Mandatory Access Control (MAC) procedures are not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, as they do not provide or offer the encryption or the protection for the sensitive customer data or the information that is transmitted or communicated over the data link layer, and as they do not prevent or reduce the risk of unauthorized or inappropriate access, disclosure, modification, or interception of the sensitive customer data or the information by the third parties or the attackers who capture or monitor the sensitive customer data or the information over the data link layer.
D. Segregation of duties is not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, but rather a type of control or a protection technique or mechanism that separates or divides the tasks or the functions that are related or relevant to the resources or the data within a system or a service, among the different or the various users or the devices within an organization, such as the bank teller, the supervisor, or the manager, to prevent or to reduce the risk of fraud, error, or abuse of the resources or the data within the system or the service, by the user or the device that has the complete or the full control or authority over the resources or the data within the system or the service, such as the bank teller, the supervisor, or the manager. Segregation of duties can provide a moderate level of security or protection for the system or the service, as it can prevent or reduce the risk of fraud, error, or abuse of the resources or the data within the system or the service, by the user or the device that has the complete or the full control or authority over the resources or the data within the system or the service, such as the bank teller, the supervisor, or the manager, and as it can also provide the accountability, the transparency, or the auditability of the tasks or the functions that are related or relevant to the resources or the data within the system or the service, among the different or the various users or the devices within an organization, such as the bank teller, the supervisor, or the manager. However, segregation of duties is not the most effective implementation for ensuring data privacy when sensitive customer data is going to be added to a database, as it does not provide or offer the encryption or the protection for the sensitive customer data or the information that is transmitted or communicated over the data link layer, and as it does not prevent or reduce the risk of unauthorized or inappropriate access, disclosure, modification, or interception of the sensitive customer data or the information by the third parties or the attackers who capture or monitor the sensitive customer data or the information over the data link layer.
