Rule set configuration
Rule sets are the building blocks of your web security policy. This section tells you how to add rule sets
to your configuration by importing them from a rule set library. It also explains step by step how you
create a rule set on your own.
Import a rule set
A rule set library provides complete rule sets, which you can import if a particular function is missing in
your implemented rule set system or the implemented rule sets do not suit your requirements.
Complete the following procedure to import a rule set from the library:
1 Go to Policy | Rule Sets.
2 On the rule set tree, navigate to the position where you want to insert the new rule set.
3 From the Add drop-down menu, select Rule Set from Library. A window with a list of the library
rule sets opens.
4 Select the rule set you want to import, for example, the Gateway Antimalware rule set.
If conflicts arise when importing this rule set, they are displayed in the window.
Note: Conflicts arise when a rule set uses configuration objects, such as lists or settings, that already exist
in an appliance configuration.
5 Use one of the following methods to solve conflicts:
• Click Auto-Solve Conflicts and choose one of the following strategies for all conflicts:
• Solve by referring to the existing objects — If rules of the imported rule set refer to objects
existing in the appliance configuration under the same names, references are made to apply to
these existing objects.
• Solve by copying and renaming to suggested — If rules of the imported rule set refer to
objects existing in the appliance configuration under the same names, these objects are also
used, but are renamed, so as to avoid conflicts.
• Click the listed conflicts one after another and solve them individually by choosing either of the two
above strategies each time.
6 Click OK. The rule set is inserted in the rule sets tree. It is enabled by default.
Note: Together with the rule set, lists and settings can be implemented in your configuration. The rules of
the rule set need these items to make decisions on blocking and other actions.
7 If necessary, use the blue arrows above the rule sets tree, to move the rule set to where you want it
to be.
8 Click Save Changes.
