Selecting your active policy rules Selecting your active policy rules 7-22 Creating Rules and Groups Organize the assigned rules and groups within the selected rule group— To organize the rules and groups in the Assigned Rules and Groups table, click and drag each entry to the desired location. For information on organizing your rule groups, see “Ordering proxy rules within a rule group” on page 4-5. Edit the description for a rule group—To edit the description for a rule group, place your cursor in the Description field and add or modify the text as needed. Save the changes you made to the rule group—To save your changes, click OK. When you select rule groups in the Active Rules window (one for proxy rules and one for IP Filter rules), they will begin actively filtering traffic coming into and leaving the Sidewinder G2. When you initially configure your Sidewinder G2, a default rule group is automatically assigned as your active policy (the rules contained in those groups will vary depending on the choices you made in the Configuration Wizard). All rules and groups that you have created that are not part of the active rules (that is, rules that are not included in the active group, or in a rule group that is nested in the active group) will remain inactive unless you add them to the active rule group or to a group that is part of the active rule group. You can modify your existing active rule group to add or delete rules and/or nested rule groups as your security needs change. You can also re-organize the rule group entries as needed. For a more detailed overview of the active rules and how they work, see Chapter 4. Viewing the active policy To view the active rules currently configured for your Sidewinder G2, using the Admin Console select Policy Configuration -> Rules and then click View Active Policy. The Active Rules window appears.
Figure 7-11. Active Rules window About the Active Rules window Selecting your active policy rules This window allows you to view the active rules currently in use on your Sidewinder G2. The active rules listed in each table consist of all of the rules (including both individual rules and rules included in nested groups) and determine the order in which traffic will be processed. Which rules appear in each table are determined by the rule group that is displayed in the Active Group field. In this window, you can perform the following actions: Select a new active rule group—To select a new active rule group that will enforce traffic coming into and leaving the Sidewinder G2, see “Modifying the active rule groups” on page 7-24. (The window is similar for IP Filter and Proxy rule groups.) View the IP Filter properties—To view the properties configured for the IP Filter rules contained in the active IP Filter group, click the IP Filter Properties button. The IP Filter General Rule Properties window appears. See “About the IP Filter General Properties window” on page 7-25. Determine which group a rule belongs to—Rules that are part of a nested rule group have a folder icon next to their name. Creating Rules and Groups 7-23
