As a security administrator, you recommend to the web development team that a CAPTCHA be added to the registration page for user accounts. This is an example of which security control?

When registering for an account, users are required to enter the alphanumeric characters displayed on the webpage, which serves as a deterrent control by preventing automated bots from registering and verifying that a real person is registering. Detective controls, on the other hand, are designed to detect intrusions in real-time and uncover any violations. If a security measure is too difficult or impractical to implement at the moment, a compensating control can be used to meet the requirement. Degaussing is a process that alters the magnetic field to erase data from magnetic storage media.
