Which action prevents buffer overflow attacks?

Show Suggested Answer Hide Answer
Suggested Answer: A

TCP injection is an attack where the attacker sends crafted packets into an existing TCP session. These packets appear to be part of the session.

The presence of many SYN packets with the same sequence number, source, and destination IP but different payloads indicates that an attacker might be injecting packets into the session.

This method can be used to disrupt communication, inject malicious commands, or manipulate the data being transmitted.

Using a Linux OS? I don't think the operating system itself is the main factor in preventing buffer overflows. It's more about the coding practices and input validation techniques used. I'm leaning towards C as the right answer.

Variable randomization? That doesn't sound right to me. I think the key is making sure you properly validate and limit the input that users can provide. C seems like the best answer here.

I'm a bit confused on this one. Is the diamond symbol for indicating direction, or is it for a decision point? I'll have to review my notes to make sure I have the right understanding.
