Historically, a company has had issues with users plugging in personally owned removable media devices into corporate computers. As a result, the threat of malware incidents is almost constant. Which of the following would best help prevent the malware from being installed on the computers?
Correct Answer:
D
EDR stands for Endpoint Detection and Response, which is a technology that monitors, detects, and responds to cyber threats on endpoint devices, such as laptops, desktops, servers, or mobile devices.

EDR also provides tools and capabilities to respond to threats, such as isolating infected devices, blocking malicious processes, removing malware, or restoring files.
Historically, a company has had issues with users plugging in personally owned removable media devices into corporate computers. As a result, the threat of malware incidents is almost constant. EDR would best help prevent the malware from being installed on the computers by detecting the insertion of removable media devices and scanning them for any malicious code or files. EDR would also alert the security team of any potential infection and enable them to take immediate action to contain and remediate the threat.

Which of the following can be used by an authentication application to validate a user's credentials without the need to store the actual sensitive data?
Correct Answer:
C
Password hash is a method of storing a user’s credentials without the need to store the actual sensitive data. A password hash is a one-way function that transforms the user’s password into a fixed-length string of characters that cannot be reversed. The authentication application can then compare the password hash with the stored hash to validate the user’s credentials without revealing the original password. References: 1
