Defining Policies on Panorama
Device Groups on Panorama™ allow you to centrally manage firewall policies. You create policies on Panorama either as
Post Rules; Pre Rules and Post Rules allow you to create a layered approach for implementing policy.
You can define Pre rules and Post rules in a shared context, as shared policies for all managed firewalls, or in a device group context, to make the rules specific to a device group. Because you define Pre rules and Post Rules on Panorama and then push them from Panorama to the managed firewalls, you are able to view the rules on the managed firewalls but you can edit the Pre Rules and Post Rules only in Panorama.
- Pre Rules—Rules that are added to the top of the rule order and are evaluated first. You can use pre-rules to enforce the Acceptable Use Policy for an organization. For example, you can block access to specific URL categories or allow DNS traffic for all users.
- Post Rules—Rules that are added at the bottom of the rule order and are evaluated after the pre-rules and rules that are locally defined on the firewall. Post-rules typically include rules to deny access to traffic based on the App-ID™, User-ID™, or Service.
- Default Rules—Rules that specify how the firewall handles traffic that does not match any Pre Rules, Post Rules, or local firewall rules. These rules are part of the predefined Panorama configuration. ToOverrideand enable editing of select settings in these rules, see Overriding or Reverting a Security Policy Rule.
Preview Rulesto view a list of all rules before you push the rules to the managed firewalls. Within each rulebase, the hierarchy of rules is visually demarcated for each device group (and managed firewall) to make it easier to scan through a large numbers of rules.
When you add or edit a rule in Panorama, a
Targettab displays. You can use this tab to apply the rule to specific firewalls or descendant device groups of the
Device Group(or Shared location) where the rule is defined. In the
Targettab, you can select
Any(default), which means the rule applies to all the firewalls and descendant device groups. To target specific firewalls or device groups, deselect
Anyand select specific firewalls or device groups by name. To exclude specific firewalls or device groups, deselect
Any, select the specific firewalls and device groups by name, and select
Target to all but these specified devices. If the list of device groups and firewalls is long, you can apply Filters to search the entries by attributes (such as Platforms) or by a text string for matching names.
After you successfully add and push a rule in Panorama,
Rule Usagedisplays whether the rule is Used by all devices in the device group, Partially Used by some devices in the device group, or Unused by devices in the device group. Panorama determines rule usage based on managed firewalls with Policy Rule Hit Count (enabled by default). In the Panorama context, you can view the rule usage for a Shared policy rule across all device groups. Additionally, you can change the context to an individual device group and view the total policy rule usage across all devices in the device group.
Preview Ruleswill show the Hit Count, Last Hit, and First Hit for each policy rule for the device group. The total traffic hit count, as well as the first and last hits timestamps, persist through reboot, upgrade, and dataplane restart events. See Monitor Policy Rule Usage.
Administrative users who have access to the Policies tab can export the policy rules that are displayed on the web interface as
PDF/CSV. See Export Configuration Table Data.
