Blocking SNMP SET

RiteshThakker — Thu, 09 May 2019 10:59:26 GMT

Hi,

I have no control on the SNMP Server so unable to enforce policy.

As per security requirements I want to block / deny SNMP SET packets passing through Palo Alto firewalls as well as targeted to the Palo Alto firewall management plane. However I want to allow SNMP Get from specific SNMP Server and allow Traps to SNMP Server. I was wondering if it possible to achieve?

Thanks

anything going through the firewall can be controlled via securiotypolicy and anything accessing the management plane can be controlled through the mgmt ACL

SNMP traps have their own application, so that should be easy, i'm not sure about snmp set... you could possibly look into creating a custom app or custom threat with some strings to match a set command
