Question

Typical firewall programs or hardware devices filter all information coming through the Internet to your network or computer system. Which two of the following are techniques used to minimize the risk of harmful intrusions into a computer or network?

A) Intrusion Detection System (IDS)
B) Intrusion Prevention System (IPS)
C) Network Address Translation (NAT)
D) Quality of Service (QoS)

Answer 1

To minimize harmful intrusions, firewall programs and hardware devices can use Intrusion Detection Systems (IDS) to monitor and alert of suspicious activities, and Intrusion Prevention Systems (IPS) to analyze and block malicious traffic.

Step-by-step explanation:

To minimize the risk of harmful intrusions into a computer or network, firewall programs or hardware devices utilize various techniques. Two effective techniques are:

• Intrusion Detection System (IDS): This technology is designed to detect unauthorized access or anomalies on a network or a computer system. It acts as a surveillance system that monitors network traffic and alerts administrators to suspicious activities.
• Intrusion Prevention System (IPS): An IPS not only detects potential threats but also actively works to prevent them from causing harm. It functions by analyzing network traffic, identifying and blocking malicious packets.

While Network Address Translation (NAT) and Quality of Service (QoS) play roles in the overall security and management of network resources, they are not specifically targeted at minimizing harmful intrusions in the way that IDS and IPS do.
