Ensure sshd MaxAuthTries is configured
Опис
The MaxAuthTries parameter specifies the maximum number of authentication attempts permitted per connection. When the login failure count reaches half the number, error messages will be written to the syslog file detailing the login failure. Setting the MaxAuthTries parameter to a low number will minimize the risk of successful brute force attacks to the SSH server. While the recommended setting is 4, set the number based on site policy. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).
Како се проверава
Метод провере: Команда љуске
command -v sshd >/dev/null 2>&1 || exit 1; out=$(sshd -T 2>/dev/null) || exit 1; r=compliant; for p in '^maxauthtries[[:blank:]]+[1-4]$'; 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 set the parameter as follows:: MaxAuthTries 4 Re-cycle the sshd daemon to pick up the configuration changes: stopsrc -s sshd startsrc -s sshd
