Use Policy Optimizer to add apps seen on a port-based
Security policy rule to an existing application-based rule.
In some cases, you may want to add applications
learned (seen) on a port-based rule to a rule that already exists.
For example, an administrator may create a cloned application-based
rule for general business web applications from a port-based rule
that allows internet access (a port 80/443 rule). Later, the administrator
notices that the port-based internet access rule has seen more general
business applications and wants to add some or all of them to the
cloned application-based rule (cloning another application-based
rule for the same type of application would create an unnecessary
rule and complicate the rulebase).
This example assumes that
an application-based Security policy rule to control general business
traffic already exists or was cloned from a port-based internet
access rule, similarly to the Rule Cloning Migration Use Case: Web Browsing and SSL Traffic. In that example,
we cloned an application-based rule from the port-based internet
access rule and changed the new rule’s Service to application-default
to prevent web-based applications from using non-standard ports.
addition to adding applications to an existing application-based
rule, you can add applications to an existing port-based rule. This converts
the port-based rule to an application-based rule for the applications
you add to the rule. If you do this, go to the rule and change the
Service to application-default to prevent the applications from
using non-standard ports (also, the Service configured on the rule
may not match the application).
does not apply to using the New App Viewer to add
App-ID Cloud Engine (ACE) applications to an existing rule (see
the ACE documentation for
examples of how to do this); ACE requires a SaaS Security Inline license.
You check the port-based internet access rule
and discover that the rule has seen general business applications
and that you need to allow some of them for business purposes.
Select the general business apps you want to add to the
Add to Existing Rule
of the rule to which you
want to add the applications, in this example,
to Existing Rule
to add the selected applications to
The updated rule now controls the original applications
on the rule and the applications you just added.
