Man-In-The-Middle-Attack

The topic that Im going to discuss is Man in the middle attack. The man-in-the middle attack intercepts a communication between two systems. For example, in an http transaction the target is the TCP connection between client and server. Using different techniques, the attacker splits the original TCP connection into 2 new connections, one between the client and the attacker and the other between the attacker and the server, as shown in figure 1. Once the TCP connection is intercepted, the attacker acts as a proxy, being able to read, insert and modify the data in the intercepted communication.

In a simple explanation, man in the middle is one kind of the computer crime that duplicate the information that the user sent over. It's basically means the private and confidential info are passing around through the net. Let's have a simple example, Alice and Jason is using webcam through MSN, the attacker would intercept the video call and get to see what the user are seeing. It might be use for illegal purposes.

So far me and the friends around me are never involved in this kind of computer crimes therefore I have no experience to share with you guys. Anyway, I knew some solution to avoid this man in the middle attack crimes. By using Encryption, which is you type the "unknown words" then your friend would read it through some softwares while the attackers can't get your information so that they couldn't attack your pc and your confidential information as well.

Let's show you guy a picture to understand better.

Hope it works and makes you understands more about Man in the middle attack computer crimes. =)
