To add a new policy rule, do one of the following:
To modify a rule, click the rule.
If the rule is pushed from Panorama, the rule is read-only on the firewall and cannot be edited locally.
Revertactions pertain only to the default rules that are displayed at the bottom of the Security rulebase. These predefined rules—allow all intrazone traffic and deny all interzone traffic—instruct the firewall on how to handle traffic that does not match any other rule in the rulebase. Because they are part of the predefined configuration, you must
Overridethem in order to edit select policy settings. If you are using Panorama, you can also
Overridethe default rules, and then push them to firewalls in a Device Group or Shared context. You can also
Revertthe default rules, which restores the predefined settings or the settings pushed from Panorama. For details, see Overriding or Reverting a Security Policy Rule.
Rules are evaluated top down and as enumerated on the
Policiespage. To change the order in which the rules are evaluated against network traffic, select a rule and click
Move Top, or

To identify rules that have not been used since the last time the firewall was restarted, select
Highlight Unused Rules. You can then decide whether to disable the rule or delete it. Rules not currently in use are displayed with a dotted yellow background.
Each firewall maintains a flag for the rules that have a match. Because the flag is reset when a dataplane reset occurs on a reboot or a restart, monitor this list periodically to determine whether the rule has had a match since the last check before you delete or disable it.
To show or hide the columns that display in the
Policiespages, select this option next to the column name to toggle the display of each column.

To find objects used within a policy based on their name or IP address, use the filter option. After you apply the filter, you will see only the items that match the filter. The filter also works with embedded objects. Example: when you filter on 10.1.4.8, only the policy that contains that address is displayed:
