A honeypot in cybersecurity is a decoy system designed to attract and monitor potential attackers, mimicking real systems to lure them in and log their activities for analysis. This helps security professionals understand attack strategies and improve defenses. There are low-interaction honeypots, which simulate limited services, and high-interaction honeypots, which mimic entire systems for deeper insights.

To prevent a Man-In-The-Middle (MITM) attack, several strategies can be employed:

1. Encryption: Use strong encryption protocols like HTTPS, TLS, and SSL to secure data transmission.
2. Authentication: Implement multi-factor authentication (MFA) to add extra security layers.
3. Public Key Infrastructure (PKI): Utilize certificates to authenticate servers and clients.
4. Secure Wi-Fi: Avoid public Wi-Fi for sensitive transactions and secure private Wi-Fi with strong passwords and WPA3 encryption.
5. VPNs: Use Virtual Private Networks to encrypt internet traffic, especially on public networks.
6. Awareness and Training: Educate users on the risks of MITM attacks and the importance of verifying website authenticity.

Tools for prevention include Wireshark for monitoring network traffic, Burp Suite for identifying vulnerabilities, SSL/TLS certificates like those from Let’s Encrypt, VPN services like NordVPN and ExpressVPN, and HSTS (HTTP Strict Transport Security) to enforce HTTPS connections.
