If there are concerns that someone might inadvertently
add other interfaces to the wf-vm-zone, clone the WildFire VM Interface security
policy and then in the
Action
tab for the
cloned rule, select
Deny
. Make sure this
new security policy is listed below the WildFire VM interface policy.
This will override the implicit intra-zone allow rule that allows
communications between interfaces in the same zone and will deny/block
all intra-zone communication.
