Ensure sshd PermitEmptyPasswords is disabled
Opis
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).
Kako se proverava
Metod provere: Komanda ljuske
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"- Očekivani izlaz
compliant
Kako se ispravlja
Metod ispravke: Smernica ili zakrpa infrastrukture
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
