Question 66

IDS allows a network administrator to analyze attacks coming from the Internet without affecting latency.

An Intrusion Detection System (IDS) passively monitors network traffic and analyzes potential threats without intervening in the data flow, thus ensuring that latency is not affected.

A) IPS

An Intrusion Prevention System (IPS) actively blocks and prevents attacks in real-time, which can introduce latency as it inspects and reacts to incoming traffic. This proactive approach can impact network performance, making it unsuitable for analyzing attacks without affecting latency.

B) IDS

An Intrusion Detection System (IDS) is designed to passively monitor and analyze network traffic for signs of malicious activity. Since it does not interfere with the traffic flow but rather observes it, it allows for the analysis of attacks without adding latency to the network.

C) Load balancer

A load balancer distributes network traffic across multiple servers to optimize resource use and enhance performance. While it can improve response times, it does not focus on threat analysis and does not inherently provide the capability to analyze attacks, making it irrelevant to the question of latency in attack analysis.

D) Firewall

A firewall serves to block or allow traffic based on predetermined security rules, which can introduce latency as it processes each packet. While essential for network security, a firewall does not analyze attacks in the same manner as an IDS does and can affect latency depending on its configuration.

Conclusion

The IDS is the only option that fulfills the requirement of analyzing attacks without impacting latency, as it operates in a passive manner. In contrast, the IPS, load balancer, and firewall either introduce latency or do not focus specifically on the analysis of attacks. Thus, the IDS is definitively the correct choice for this scenario.
