Ensure sshd PermitEmptyPasswords is disabled

КритичнаНиво 1Аутоматскаaix

Опис

The recommendation is to edit the /etc/ssh/sshd_config file to ensure that the SSH daemon does not authenticate users with a null password. If password authentication is used and an account has an empty password, the SSH server must be configured to disallow access to the account. Permitting empty passwords could create an easy path of access for hackers to enter the system. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

Како се проверава

Метод провере: Команда љуске

shell

command -v sshd >/dev/null 2>&1 || exit 1; out=$(sshd -T 2>/dev/null) || exit 1; r=compliant; for p in '^permitemptypasswords[[:blank:]]+no$'; do printf '%s\n' "$out" | grep -Eiq -- "$p" || r="not matched: $p"; done; echo "$r"

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Edit the /etc/ssh/sshd_config file to disable the acceptance null passwords: vi /etc/ssh/sshd_config Replace: #PermitEmptyPasswords no With: PermitEmptyPasswords no Re-cycle the sshd daemon to pick up the configuration changes: stopsrc -s sshd startsrc -s sshd
