How does an attacker observe network traffic exchanged between two users?

Show Suggested Answer Hide Answer
Suggested Answer: B

A man-in-the-middle (MITM) attack occurs when an attacker secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other. In this scenario, an attacker can observe network traffic exchanged between two users by placing themselves in between their communication channel.Reference:= Cisco Blogs - New Cybersecurity and Cloud Skills to Protect Companies from Cybersecurity Attacks of the Future

Command injection doesn't relate to traffic observation, right?

Denial of service seems off-topic here; it disrupts services rather than observing traffic. I feel like man-in-the-middle is the best choice.

I practiced a similar question, and I believe command injection doesn't really relate to observing traffic, so it must be one of the other options.

I'm not entirely sure, but I remember something about port scanning being more about discovering open ports rather than observing traffic.

This is a classic network security question. The key is to think about how an attacker could observe the traffic between two users. B, man-in-the-middle, is the correct answer.

I'm a bit confused by this question. I'm not sure if I fully understand the concept of a man-in-the-middle attack. Maybe I should review my notes on network security before answering.

Okay, let me think this through. I know that port scanning is used to identify open ports, so that's not the right answer. Command injection and denial of service are different types of attacks. I'm going to go with B, man-in-the-middle.

I'm going with B. The only way to really spy on someone's conversation is to get in the middle of it. Kinda creepy, but hey, that's the life of a hacker!

Definitely B. Port scanning, command injection, and denial of service don't allow the attacker to observe the actual traffic, just disrupt the connection.
