What is MITM? How to Attack & Prevent?
The MITM or Man in the middle attack is considered an active attack where an attacker creates a connection between the targets. Man in the middle attack is a risk to your privacy.
In this attack, victims think that they are communicating with each other, but in reality the attacker control and monitor all the traffic. Attacker impersonates a legitimate user to both the targets. The attacker sits between the victims and all the traffic goes through him so he can do whatever he wants with the data.
The purpose of this attack is to steal private information like passwords, Account information, Credit card details, etc.

For making our communication secure we must ensure the following three attributes.
- Confidentiality – Only the authorized user is able to access the information.
- Integrity – Information should not be altered by an unauthorized person.
- Authenticity – Only authentic users are able to communicate.
