Ensure access SSH to CLI interface is restricted to needed IP addresses only

Опис

To limit ssh access to trusted IPs only PASS requires sys sshd allow to be a list of addresses (not ALL). Audited against tmsh output with defaults shown: save the concatenated output of 'tmsh list auth password-policy all-properties', 'tmsh list auth source all-properties', 'tmsh list auth remote-user all-properties', 'tmsh list auth radius all-properties', 'tmsh list sys httpd all-properties', 'tmsh list sys sshd all-properties', 'tmsh list sys global-settings all-properties', 'tmsh list cli global-settings all-properties', 'tmsh list sys ntp', 'tmsh list sys snmp all-properties', 'tmsh list sys syslog' and 'tmsh list net self all-properties'. Patterns are scoped to the named top-level block.

Како се проверава

Метод провере: Образац конфигурације

Образац: (?m)^sys sshd \{\n(?:[ \t]+[^\n]*\n)*?[ \t]+allow \{ (?:[0-9a-fA-F.:/\-]+ )+\}[ \t]*$

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

tmsh modify sys sshd allow replace-all-with { 10.0.0.0/255.255.255.0 } tmsh save sys config # CIS guidance: 1-Log in to the Configuration utility. 2-Go to System > Platform. 3-For SSH IP Allow, select Specify Range and then enter the IP addresses or address ranges for the remote systems allowed to use SSH to communicate with this system.
