Man-in-the-middle (MITM) attack may be an anomaly created by an intruder to obstruct communication between 2 parties wherever the communication has to be direct. In this case, each party tends to be unaware of the attack that has come about. The involvement of physical proximity or the use of malware to hinder communications (a man-in-the-browser attack) is the elementary section of this attack.
Generally, the monetary transactions, secured connections, and other interactions involving username and password are attacked.
Utilization of the various ways in obstructing communications like email, session, or IP hijacking, Wi-Fi® eavesdropping, Trojan attacks, DNS spoofing, or HTTP injections are a part of this attack.
Explaining the process of MITM attack would be effective in the form of an example. Person A and person B intends to send messages to each other, opposite to which, person C wants to obstruct their communication and hence, initiates the process of MITM attack.
Suppose, person A and person B wants to message each other their bank accounts number for cash withdrawal. Meanwhile, person C locates a security hole which is able to permit to hinder each of their communication and become the man-in-the-middle between their communication. Whatever they’ll discuss, will be gathered by person C, and that’s precisely how a forgery takes place. This whole development is thought of as an MITM attack.
There are numerous ways to defend oneself from this MITM attack.
If a person is a server or a site owner,
Never miss to analyze whether the website uses secure communication protocols (like TLS and HTTPS). These protocols act as a defender against spoofing attacks.
See to it that website applications make use of SSL/TLS to secure each website page rather than pages requiring authentication only. This step will stop the attackers from accessing session cookies on those portions of the website which are unsecured.
If a person is a user of the internet,
Be sure to use the revised anti-malware software for protecting and maintaining the security of the online devices. Ensuring that the software system and browser are briefed or not is obligatory.
Never use unsecured, distrusted Wi-Fi connections because attackers can easily scan the available Wi-Fi hotspots to search these insecure or default passwords, or those router configurations that are easily exploitable.
Maintaining extreme caution whilst connecting to publicly-accessible Wi-Fi routers is extremely necessary. If a user uses public Wi-Fi connections, remember to configure the devices to use a Virtual Private Network (VPN) without fail.
Ensuring secure configuration of the home and office Wi-Fi routers or the use of adequate precautions for online communications is a necessity.
Check whether the websites that the user’s access includes the https:// protocol in their URLs and have certificate authority-signed SSL certificates.
Paying attention to browser notifications regarding unsecured websites and immediate coming out of secure websites after working with them is necessary.
Warnings regarding harmful MITM attacks are found in a number of cPanel and WHM options, like in cPanel’s Git Version Control interface (cPanel >> Home >> Files >> Git Version Control). Here, warnings are displayed just in case the system fails to validate some unknown clone URL’s public fingerprint. To be acknowledged about how to resolve this issue, users can read our Git Version Control documentation.
