What is Port 3632?
Port 3632 is the default port for distcc, a distributed C/C++ compiler that spreads compilation jobs across multiple machines on a network. Build systems use distcc to dramatically speed up large software compilations. An unprotected distcc daemon can be exploited to execute arbitrary code on the compilation server.

Security Considerations
Port 3632 (distcc) 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.
