Which of the following is a control measure for preventing a data breach?

This is because data encryption is a type of control measure that prevents a data breach, which is an

unauthorized or illegal access or use of data by an external or internal party. Data encryption can

prevent a data breach by protecting and securing the data using a code or a key that scrambles or

transforms the data into an unreadable or incomprehensible format, which can only be decoded or

restored by authorized users who have the correct code or key. For example, data encryption can

prevent a data breach by encrypting the data in transit or at rest, such as when the data is sent over a

network or stored in a device. The other control measures are not used for preventing a data

breach.Here is why:

Data transmission is a type of process that transfers and exchanges data between different sources or

systems, such as databases, cloud services, or web applications. Data transmission does not prevent

a data breach, but rather exposes the data to potential risks or threats during the transfer or

exchange. However, data transmission can be made more secure and less vulnerable to a data breach

by using encryption or other methods, such as authentication or authorization.

Data attribution is a type of feature or function that assigns and tracks the ownership and origin of

the data, such as the creator, modifier, or source of the data. Data attribution does not prevent a data

breach but rather provides information and evidence about the data provenance and history.

However, data attribution can be useful for detecting and responding to a data breach by using audit

logs or metadata to identify and trace any unauthorized or illegal access or use of the data.

Data retention is a type of policy or standard that specifies and regulates the storage and

preservation of the data, such as the duration, location, or format of the data. Data retention does

not prevent a data breach, but rather affects the availability and accessibility of the data for future

use or reference. However, data retention can be optimized and aligned with the legal and ethical

requirements and standards of the industry or the organization to reduce the risk or impact of a data

breach.
