What is Port 2375?
Port 2375 is the Docker daemon's unencrypted REST API port, used for remote management of Docker containers and images. Exposing this port without authentication to the internet is extremely dangerous as it allows full control of the Docker host, effectively providing root access to the system. This port should never be exposed publicly.

Security Considerations
Port 2375 (Docker (unencrypted)) is classified as critical risk. This port should not be exposed to the public internet. The service transmits data without encryption, making it vulnerable to eavesdropping, credential theft, and man-in-the-middle attacks.
Recommendation: Block this port at the firewall. Use encrypted alternatives (SSH, SFTP, HTTPS) instead.
