Ensure FTP.DATA configuration statements enforce AT- TLS protection

AltaNível 1Revisão manualibm-z

Descrição

During the TLS handshake process, mutually acceptable suite of cryptographic algorithms is selected by the server and client. The algorithms specified in the selected suite are used to cryptographically protect the data that subsequently flows between the two. To apply TLS protection of adequate strength, the FTP daemon must be configured to use AT-TLS protection.
