Security Policy for Wildcard-Based Apps

1. Create a Custom URL category and add the wildcard URLs to the category.

   1. Go toManageConfigurationNGFW and Prisma AccessSecurity ServicesURL Access Management.
   2. Under Custom URL categories, Add Category.
   3. Give a descriptive Name for the custom URL category and select a Type of URL List.
   4. Add the wildcard URLs you created in ZTNA Connector to the Items.
   5. Save your changes.

2. Create a URL access Management Profile and add the custom URL category you created to it.

   1. While still in the URL Access Management area, select URL Access Management Profiles.
   2. Select an existing profile to modify or Add Profile.
   3. Add the Custom URL category you created to the profile.
   4. Select the following parameters:

      • Site Access: Allow
      • User Credential Submission: Allow
   5. Save your changes.

3. Create a profile group and attach the URL Access Management Profile to the group.

   1. Go to ConfigurationNGFW and Prisma AccessSecurity ServicesProfile Groups.
   2. Add a profile group, specifying the URL Access Management Profile you created.

4. Create a policy to allow the profile group and the IP addresses for the ZTNA Connector Application IP Blocks.

   1. Go to WorkflowsPrisma Access SetupPrisma AccessPrisma Access Setup and make a note of the Application IP Blocks under ZTNA Connector IPs.

   2. Go to ManageConfigurationNGFW and Prisma AccessObjectsAddressAddresses and Add address objects based on the IP addresses you retrieved.

      If you have IP Subnet-based apps, create address objects for those subnets as well.

   3. Go to ManageConfigurationNGFW and Prisma AccessObjectsAddressAddress Groups and Add the address objects you created to an address group.

   4. Go to ManageConfigurationNGFW and Prisma AccessSecurity ServicesSecurity PolicyPre Rules and Add a Security policy to allow access to all application IP address blocks, specifying the Address Group and Profile Group you created in an earlier step.

      Adding this Security policy allows all traffic from wildcard-based app traffic to be passed while ZTNA Connector discovers the apps based on wildcards. Without the rule to allow the Application IP Blocks, users can't access wildcard-based apps.

      You can leave this policy in place until ZTNA Connector discovers the wildcard-based apps. Then, you can choose to disable this policy and add Security policy rules for each of the discovered apps.

5. After ZTNA Connector has discovered the apps based on wildcards, configure a Security policy for the apps that you added using FQDNs.

   1. Go to WorkflowsZTNA ConnectorApplication TargetsFQDN Targets and make a note of the FQDNs used by the apps.
   2. Create an Address object for the FQDN (ManageConfigurationNGFW and Prisma AccessObjectsAddressAddresses).

      Select the Prisma Access configuration scope.
   3. Add an address object with the Type of FQDN: Domain Name and enter the FQDN of the discovered application.

      Enter the FQDNs for the FQDN targets.

   4. Go to ManageConfigurationNGFW and Prisma AccessSecurity ServicesSecurity PolicyPre Rules and Add a Security policy to allow access to the discovered apps.

6. Push Config to save and push your configuration changes.
7. (Optional) After you have created the Security policy based on FQDNs, remove the policy based on the IP application blocks.
