What action does an Intrusion Prevention System (IPS) perform that an IDS does not?

• A. Logging network traffic
• B. Active prevention of threats
• C. Traffic analysis for patterns
• D. Providing secure VPN connections

Answer: (B)

An Intrusion Prevention System (IPS) actively prevents threats by taking immediate action to block or mitigate those threats as they occur in real-time. This proactive approach distinguishes it from an Intrusion Detection System (IDS), which primarily focuses on monitoring and analyzing network traffic to detect suspicious activities but does not take direct action to neutralize those threats. Therefore, while an IDS might log network activity, analyze traffic patterns, or provide alerts, it does not engage in defensive measures to stop potential intrusions. The IPS, on the other hand, is designed specifically to respond to threats, making it a more robust choice for active network defense.
