Which option completes the PPS four-function description for the fourth function?

• A. Provide a response to deny adversaries from reaching their target
• B. Deter the occurrence of an event
• C. Delay adversaries from reaching their target
• D. Detecting undesirable event or attack

Answer: (A)

The fourth function in PPS protections focuses on the action taken after a threat is identified: a response designed to deny adversaries the ability to reach their target. This goes beyond prevention, sensing, or slowing an intruder; it involves concrete measures to interrupt, stop, or mitigate the threat and protect the asset. Think of it as the reactive phase where security personnel, alarms, lockdowns, and coordinated responses come into play to deter further advancement and neutralize the immediate danger. Deterrence aims to prevent events from starting, so it doesn’t describe the immediate actions taken during an intrusion. Detection is about recognizing that something is wrong, not the actions that stop the intruder. Delay is about slowing progress, not necessarily stopping it. The option that describes providing a response to deny adversaries from reaching their target matches the intent of the final function, which is to act decisively to stop or minimize the attacker’s success.
