SSH
SmartFTP implementerer følgende funksjoner i SSH-protokollen (Secure Shell).
Funksjoner
Security Standard Compliance
- NIST FIPS 140-2
- NIST FIPS 140-3
- NIST FIPS 186-4
- NIST Special Publication 800-131A
Godkjenning
Følgende godkjenningsmetoder støttes:- Passord
Brukernavn/passord og keyboard-interactive-godkjenning. Støtter også forespørsel om passordendring. - Fellesnøkkel
Nøkkelfil (PuTTY, VanDyke's SecureCRT, SSH.com, OpenSSH, PEM), X.509-sertifikater, Microsoft Windows-sertifikater fra et sertifikatlager eller et smartkort (PKCS #11). - Kerberos v5 (GSSAPI/SSPI)
Støtte for implementeringene Microsoft Windows Kerberos (SSPI) og MIT Kerberos (GSSAPI). - Vertsbasert
Godkjenning med en vertsnøkkelfil eller et sertifikat. - RSA SecurID
RSA SecurID two-factor authentication.
Kryptering
