Fill in the blank with the appropriate term. A _____________ is a technique to authenticate digital documents by using computer cryptography. Answer: signature

The correct answer is D. NIDS. There appears to be an error in this question. The listed correct answer of D (NIDS) does not match the question stem - a digital signature is what authenticates digital documents via cryptography, and none of the four choices represent that concept.

Explanation

There appears to be an error in this question. The listed correct answer of D (NIDS) does not match the question stem - a digital signature is what authenticates digital documents via cryptography, and none of the four choices represent that concept.

Here's what each option actually means, for context:

  • A. HIDS - Host-based Intrusion Detection System; monitors a single host for suspicious activity
  • B. HIPS - Host-based Intrusion Prevention System; like HIDS but actively blocks threats
  • C. DMZ - Demilitarized Zone; a network segment that separates internal networks from untrusted external ones
  • D. NIDS - Network Intrusion Detection System; monitors network traffic for suspicious patterns

None of these involve authenticating documents through cryptography. The correct fill-in answer given in the question itself ("signature") is the right concept - a digital signature uses asymmetric cryptography to verify the authenticity and integrity of a document.

Recommendation: Double-check the source of this question. It looks like the multiple-choice options may belong to a different question that was accidentally paired with this stem. You should flag it to your instructor or exam prep provider.
