5 Ways To Prevent MITM Attack 



A particular kind of cyberattack known as a man-in-the-middle (MITM) assault enables a criminal to observe your internet communications and activity. You are generally at risk from a MITM attack while accessing public Wi-Fi, like at an airport, local cafe, or bookstore. The MITM attack is hard to spot and provides hackers access to your online actions, including your emails.  

Hence, it is essential to implement and use the best endpoint security technology to safeguard your computing systems. 



What is MITM? 


A man-in-the-middle threat is what it sounds like: a hacker discreetly detects and relays messages, usually between two individuals or consumers and internal or external enterprise applications, using one of a few techniques. 

The attacker can obtain private company accounts and information, send false messages, listen in on chats, route data to accomplices, and eavesdrop on other people. 

MITM attacks pose a severe risk to online security since, in the absence of adequate defenses, they are simple to carry out, difficult to detect, and offer the attacker immediate access to sensitive data. A MITM attack can target either people or organizations. A criminal can quickly wreak extensive harm to a firm by infiltrating its IT network using this kind of attack. 

The attack intends to gather your private data, like bank account and password details or confidential company information. The perpetrator can use this data to steal revenue or your identity, utilize your cards for illicit purchases, or create chaos. 

Therefore, modern enterprises must be aware of their weaknesses and take proactive steps to protect their IT infrastructure from such assaults, given the harm they may cause. They can implement various security measures, including managed PKI, two-factor authentication, etc.  


Methods to stop MITM attacks 

Preventive measures are the most effective strategy to thwart MITM assaults.  

  1. Implement PKI


Most victims only become aware of MITM attacks after the hacker has left their sensitive data since they are difficult to detect in the early stages. Today, PKI is what shields you from MITM attacks. You engage with the web PKI each time you visit a website. Public key infrastructure serves as the foundation for managing public keys required in digital certificates.  

Asymmetric encryption, which encrypts a text but can only be decrypted by a specific user, was initially provided to the information technology industry via PKI. However, a crucial step underlies public key encryption revealing a significant flaw in the PKI system. Although sharing a symmetric key is not required, there is an absolute requirement for confidence between the two parties. 


  1. Dependable connections


Your main point of protection is a secure internet connection. To avoid this, only access websites with SSL technology and a secure HTTP connection. The added SSL security guards against MITM attacks. 

Since the URL of these websites begins with “https://,” rather than “HTTP://,” it is simple to recognize them. As an additional sign of a secure site, several browsers additionally display a padlock symbol in the URL field. Instead of the standard port 80 used by unsafe websites, the HTTPS URL by standard utilizes port 443. 

You need to do more than just sticking to safe websites. Any unsecured public Wi-Fi should be avoided. Without security, it would be simple for a hacker to breach these connections and place oneself in the way between you and the sites you’re accessing. 

Also, avoid public Wi-Fi in places with inadequate security, like coffee shops. Simply asking the waiter for the Wi-Fi password may suffice for a burglar. 




  1. VPN


Using a VPN

(a virtual private network) when logging on to the internet is one of the best practices for network security. You may send online data securely by using a VPN. 

With the help of this encryption, the MITM attack cannot snoop through your network communication. The encrypted data prevents hackers from reading your communications or discovering the websites you visit, even if they gain access to your network. 

Every company must establish a VPN and give its employees VPN software, especially those who operate remotely. 


  1. Multi-factor authentication


Multi-factor authentication can save you if a MITM threat misleads you and the criminal obtains your login credentials via a bogus website. 

To access your account with MFA, you must need another verification method in addition to your username and password. PIN entry and receiving a secret code through text message are two examples. 

You prevent a criminal from accessing your data or money by demanding several identity verification methods and an easily stolen login. 

  1. Education

Particularly susceptible to MITM and other attacks are companies. Criminals frequently target businesses, and unwary employees may unintentionally open doors for these bad guys. 

Inform staff members of the risks of a MITM attack, especially remote workers. Inform them of safe browsing techniques, such as VPNs, and caution them against using public Wi-Fi. 

Make a plan to regularly inform and re-advise your employees about the most recent online hazards. The more you promote safe online behavior among your personnel, the less likely cyberattacks will harm your company. 




As more devices are connected to Wi-Fi networks, MITM assaults will probably become more prevalent. The protection measures mentioned above are solid starting points, but for large, multi-site companies, in particular, avoiding man-in-the-middle attacks requires protecting many more weaknesses and putting additional highly technical solutions into place. 

You can protect your company and employees from MITM or cyber risks by adopting a preventive mentality and rigidly sticking to secure connections.
