This article provides information about FIPS 140-2 and how to enable this mode.
All Serv-U versions
FIPS 140-2 is a set of tested encryption specifications set by the National Institute of Standards and Technology (NIST). Enabling FIPS 140-2 mode limits Serv-U to encryption algorithms (ciphers) certified to be FIPS 140-2 compliant and ensures the highest level of security for encrypted connections.
To apply FIPS 140-2 mode to both SSL (FTPS and HTTPS) and SSH (SFTP), select the Enabled FIPS 140-2 mode box on the Encryption tab via Server Limits & Settings.
Not all client applications are able to connect to Serv-U using SSL or SSH when Serv-U is in FIPS 140-2 mode. This is because FIPS is restricted to specific ciphers and encryption methods which are not supported by all client applications. Tested applications include:
