Fix Recommendation

Configure a security policy or screen to each outbound zone to implement continuous monitoring. The following commands configure a security zone called “untrust” that can be used to apply security policy for inbound interfaces that are connected to untrusted networks. This example assumes that interfaces ge-0/0/1 and ge-0/0/2 are connected to untrusted and trusted network segments.

Apply security policy a zone example:

set security zones security-zone untrust interfaces ge-0/0/1.0
set security zones security-zone trust interfaces ge-0/0/2.0
set security policies from-zone trust to-zone untrust policy default-deny match destination-address any
set security policies from-zone trust to-zone untrust policy default-deny then deny
