Ensure tftp server services are not in use

YüksekDüzey 1Otomatikfreebsd

Açıklama

Trivial File Transfer Protocol (TFTP) is a simple protocol for exchanging files between two TCP/IP machines. TFTP servers allow connections from a TFTP Client for sending and receiving files. Unless there is a need to run the system as a TFTP server, it is recommended that the service is disabled to reduce the potential attack surface. TFTP does not have built-in encryption, access control or authentication. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
