Network Security Quiz - March 17th, 2025

Which of the following best describes the function of a proxy server in network security?

• It filters malicious traffic between networks

• It acts as an intermediary between external and internal networks

• It determines packet destinations based on Network layer addressing

• It compares network traffic to a predetermined baseline

What is the primary difference between an Intrusion Detection System (IDS) and an Intrusion Prevention System (IPS)?

• An IDS can only detect threats, while an IPS can both detect and prevent threats

• An IDS is hardware-based, while an IPS is software-based

• An IDS uses signature-based detection, while an IPS uses statistical anomaly detection

• An IDS protects individual hosts, while an IPS protects entire networks

Which of the following is NOT a typical location for a firewall?

• Between two interconnected private networks

• Between private and public networks

• Integrated within routers and switches

• Between two public networks

What are the two primary methods used by an Intrusion Detection System (IDS) to identify potential threats?

• Packet filtering and proxy services

• Network Address Translation (NAT) and port forwarding

• Statistical anomaly detection and signature-based detection

• Host-based scanning and network-based scanning

In the context of network security devices, what is the main function of a router?

• To act as an intermediary between networks

• To selectively filter or block traffic between networks

• To examine packets and determine their destination based on Network layer addressing

• To monitor network traffic and generate alerts about suspicious activity
