Question

what can an intrusion prevention system do that an intrusion detection system cant? a generate alerts. b block or reject network traffic. c complete the three - way handshake to bogus messages. d log packets.

Explanation:

An intrusion - detection system (IDS) mainly detects and alerts about potential intrusions. An intrusion - prevention system (IPS) can not only detect but also take proactive measures like blocking or rejecting network traffic to prevent intrusions from occurring. Generating alerts and logging packets can be done by IDS. Completing the three - way handshake to bogus messages is not a main differentiating function.

Answer:

B. Block or reject network traffic
