Ensure that SNMP access is allowed to trusted agents IPs only

AltaNivel 1Automatizadaf5-bigip

Descripción

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.
