Ensure that SNMP access is allowed to trusted agents IPs only

HochStufe 1Automatisiertf5-bigip

Beschreibung

To limit access to trusted SNMP agents only PASS requires sys snmp allowed-addresses to list at least one trusted manager address besides loopback. 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.

So wird geprüft

Prüfmethode: Konfigurationsmuster

Muster: (?m)^sys snmp \{\n(?:[ \t]+[^\n]*\n)*?[ \t]+allowed-addresses \{ (?:\S+ )*?(?:[02-9]\d{0,2}|1\d?|1[013-9]\d|12[0-68-9])\.\d[^\n]*\}[ \t]*$

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

tmsh modify sys snmp allowed-addresses add { 10.0.0.9 } tmsh save sys config # CIS guidance: 1-Login to Configuration utility 2- Go to System > SNMP > Agent > Configuration 3- Add trusted IP addresses in "Client Allow List"
