Final answer:
The technology that helps an organization restrict the movement or transfer of information outside its IT infrastructure is Data loss prevention (DLP). DLP tools monitor and protect sensitive data and prevent unauthorized access or transfer. Other solutions like Data masking, Data encryption, and Data validation have different primary functions.
Step-by-step explanation:
The technology that assists an organization with controlling and limiting what information is moved or transferred outside of an organization's information technology infrastructure is Data loss prevention (DLP). Data loss prevention is a set of tools and processes used to ensure that sensitive data is not lost, misused, or accessed by unauthorized users. DLP tools can monitor, detect, and block sensitive data while in use (endpoint actions), in motion (network traffic), and at rest (data storage).
Options such as Data masking transform data so that it is unusable by anyone who does not have the necessary authorization. Data encryption encodes information to ensure that only those with the key can access it. Data validation checks that the data meets certain criteria before input or processing. However, these methods do not specifically manage the transfer of information outside of an organization's IT infrastructure, which is the core function of DLP.
