Blocking Authentication Using Empty/Null Passwords for SSH

KritisLevel 1Otomatissolaris

Deskripsi

The PermitEmptyPasswords value allows for direct login through SSH without a password by a remote user/application to resources on the local host in the same way a standard remote login would. Permitting login without a password is inherently risky. Audit: PermitEmptyPasswords must be no or commented out (default no).
