Which action prevents buffer overflow attacks?

Avariable randomization

Busing web based applications

Cinput sanitization

Dusing a Linux operating system

Show Suggested 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.

Input sanitization is the way to go, folks. Gotta make sure those nasty hackers don't try to overflow our buffers with their shenanigans!

Linux, huh? Well, I guess that's one way to keep the bugs at bay, but I'm more of a Windows guy myself.

Variable randomization? Sounds like a fun party trick, but I don't think that's gonna cut it for real security.
