What is a primary function of a Network-based Intrusion Prevention System (NIPS)?

• A. Block malicious network traffic in real-time
• B. Detect attacks without preventative measures
• C. Monitor only outgoing traffic
• D. Assess system vulnerabilities

Answer: (A)

A primary function of a Network-based Intrusion Prevention System (NIPS) is to block malicious network traffic in real-time. This capability is vital in enhancing network security by actively analyzing incoming traffic and identifying potential threats based on predetermined security rules and patterns. When harmful activity is detected, the NIPS can take immediate action, such as blocking the traffic, thereby preventing potential breaches before they can cause harm to the network or systems. The proactive approach of a NIPS distinguishes it from other security measures that may only alert administrators of potential threats. By actively intervening while threats are still in transit, a NIPS serves as a critical component of an organization's defense strategy against cyberattacks. This real-time blocking feature ensures that the organization’s network is safeguarded against known exploits and suspicious behavior, contributing to a more robust security posture.
