Which function does the PTA perform to prevent unauthorized access to sensitive information?

The correct function that the PTA (Privileged Threat Analytics) performs to prevent unauthorized access to sensitive information is credential monitoring. This involves continuously overseeing and analyzing the use and management of user credentials, particularly those that have elevated privileges, which are often the target for unauthorized access attempts.

Credential monitoring helps identify suspicious activities, such as anomalous login attempts or credential misuse, by detecting patterns that deviate from normal behavior. When unusual behavior is flagged, corrective measures can be taken to mitigate potential threats before they result in a data breach or unauthorized access to sensitive information.

This proactive approach not only helps in recognizing compromised credentials but also reinforces overall security posture by ensuring that access to sensitive data is appropriately controlled and monitored. In contrast, session encryption, risk assessment, and access logging serve different purposes; for instance, session encryption secures data during transmission, risk assessment evaluates potential threats, and access logging simply records who accessed what and when without actively monitoring or assessing the nature of access itself.
