Adding Policy Rules and Setting Precedence

You can add custom lists, feeds and Threat Insight, and category filters to your policy rules. Depending on your business requirements, you can add as many feeds and Threat Insight, custom lists or category filters as you need and apply them to different security policies. Note that you must first define a custom list or a category filter before you can add it to the security policy. For information about how to create a custom list, see Creating Custom Lists. For information about how to add category or application filters, see Configuring Filters. For information about tags, see Managing Tags.

Adding Policy Rules

To add policy rules, apply actions, and set precedence, complete the following:

On the Policy Rules page of the Create New Security Policy wizard, define the Default Action for all the destinations that you have not included in the security policy, as follows:
- Allow: Grants traffic access to a domain or IP address that hits a particular feed or security policy.
- Default Redirect: Routes traffic to the default Infoblox page or a custom message that you have configured for the Redirect Page.
- Custom Redirect: Redirects traffic to a configured custom redirect, if one has been configured by the organization.
Click the Add Rule menu and choose one of the following policy types.

Note

Applying Rules

When you choose a policy type, the system adds it to the table. You can perform the following for each rule:

Click Select List to view available rules for the respective policy type.
Click the Action menu to set the action for each policy rule. For more information about what each action means, see About Rule Actions.
Set the precedence order for a policy rule by clicking the up and down arrows at the end of each row to move the rule to its desired rank. The system applies policy rules based on the precedence order. Although you have the flexibility to set precedence for each rule, it is important that you understand the ramification of putting certain policy rules before others. For more information, see Security Policy Precedence.
Choose a policy rule and click Remove to remove it from the list.

Complete the following to add a tag to a security policy:

Precedence order considerations when defining a policy-based on tags: If the Default Global Policy has higher precedence than a custom policy having network scopes defined based on tags, then the Default Global Policy will continue to work because its precedence is higher than the custom policy. For a custom policy having network scope defined based on tags to work, it should have higher precedence than the Default Global Policy.
For information on applying tags to Infoblox Threat Defense objects, see Applying Tags.

3. After you add policy rules, set actions, and precedence, you can proceed to add bypass codes.

4. Click Next in the wizard to add bypass codes. For more information, see Adding Bypass Codes to a Security Policy.

Precedence Order

Warning

Application filtering: When Local On-prem Resolution is enabled, application filters take priority when executing rules governing precedence order.

The recommended precedence order for executing rules in a security policy from highest to lowest order of precedence, is as follows:

1. Custom Lists
2. Feeds
3. Threat Insight
4. Category Filters
5. Default

While the above precedence order is recommended, the decision of precedence order is determined by the organization. When creating rules for a security policy, do keep precedence order in mind.

Note

Precedence reordering: You can reorder security policy rules precedence using drag-and-drop functionality. Click on the policy rule to be reordered on the Policy Rules page and drag it to its new location. Repeat the process as necessary until all policy rules precedence have been reordered as required.
