    When you define security rules for specific applications, you can select one or more services to limit the port numbers the applications can use. The default service is any, which allows all TCP and UDP ports. The HTTP and HTTPS services are predefined, but you can add additional service definitions. Services that are often assigned together can be combined into Service Groups to simplify the creation of Security rules.
    A service object allows you to specify the source and destination ports and protocols that a service can use. You can also create a custom service on any TCP/UDP port of your choice to restrict application usage to specific ports on your network. Additionally, you can use service objects to specify service-based session timeouts—this means that you can apply different timeouts to different user groups even when those groups are using the same TCP or UDP service, or, if you’re migrating from a port-based Security policy with custom applications to an application-based Security policy, you can easily maintain your custom application timeouts.
    After you have created your service objects, you can then group a collection of services to create a Service Group that requires the same policy enforcement. Services that are often assigned together can be combined into Service Groups to simplify the creation of security rules.

    Create a Custom Service

    Create a Custom Service (Strata Cloud Manager)

    Specify the source and destination ports and protocol that a service can use.
    Follow these steps to create a custom service.
    1. Go to ConfigurationNGFW and Prisma AccessObjectsServiceServices.
    2. Add Service.
    3. Configure the settings in this table:
      Service Settings
      Description
      Name
      Enter the service name (up to 63 characters). This name appears in the services list when defining Security security rules. The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
      Description
      Enter a description for the service (up to 1,023 characters).
      Protocol
      Select the protocol used by the service (TCP or UDP).
      Destination Port
      Enter the destination port number (0 to 65535) or range of port numbers (port1-port2) used by the service. Multiple ports or ranges must be separated by commas. The destination port is required.
      Source Port
      Enter the source port number (0 to 65535) or range of port numbers (port1-port2) used by the service. Multiple ports or ranges must be separated by commas. The source port is optional.
      Session Timeout
      Define the session timeout for the service:
      • Inherit from application (default)—No service-based timeouts are applied; the application timeout is applied.
      • Override—Define a custom session timeout for the service. Continue to populate the TCP Timeout, TCP Half Closed, and TCP Wait Time fields.
      The following settings display only if you choose to override application timeouts and create custom session timeouts for a service:
      TCP timeout
      Set the maximum length of time in seconds that a TCP session can remain open after data transmission has started. When this time expires, the session closes.
      Range is 1 - 604800. The default value is 3600 seconds.
      TCP Half Closed
      Set the maximum length of time in seconds that a session remains open when only one side of the connection has attempted to close the connection.
      This setting applies to:
      • The time period after the first FIN packet is received (indicates that one side of the connection is attempting to close the session) but before it receives the second FIN packet (indicates that the other side of the connection is closing the session).
      • The time period before receiving an RST packet (indicating an attempt to reset the connection).
      If the timer expires, the session closes.
      Range is 1 - 604800. The default value is 120 seconds.
      TCP Wait Time
      Set the maximum length of time in seconds that a session remains open after receiving the second of the two FIN packets required to terminate a session, or after receiving an RST packet to reset a connection.
      When the timer expires, the session closes.
      The range is 1 - 600. The default value is 15 seconds.
    4. Save your configuration.
    5. Select Push Config to save your configuration and deploy it to your network.

    Create a Service Group

    To simplify the creation of Security rules, you can combine services that have the same security settings into Service Groups.
    1. Go to ConfigurationNGFW and Prisma AccessObjectsServiceService Groups.
    2. Add Service Group.
    3. Configure the settings in this table:
      Service Group Settings
      Description
      Name
      Enter the Service Group name (up to 63 characters). This name appears in the services list when defining Security rules. The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
      Service
      Click Add to add services to the group. Select from the drop-down or click Service at the bottom of the drop-down and specify the settings.
    4. Save your configuration.
    5. Select Push Config to save your configuration and deploy it to your network.

    Create a Custom Service (PAN-OS & Panorama)

    Specify the source and destination ports and protocol that a service can use.
    Follow these steps to create a custom service.
    1. Go to ObjectsServices.
    2. Add a service.
    3. Configure the settings in this table:
      Service Settings
      Description
      Name
      Enter the service name (up to 63 characters). This name appears in the services list when defining Security security rules. The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
      Description
      Enter a description for the service (up to 1,023 characters).
      Shared
      Select this option if you want the service object to be available to:
      • Every virtual system (vsys) on a multi-vsys. If you clear this selection, the service object will be available only to the Virtual System selected in the Objects tab.
      • Every device group on Panorama. If you clear this selection, the service object will be available only to the Device Group selected in the Objects tab.
      Disable override (Panorama only)
      Select this option to prevent administrators from overriding the settings of this service object in device groups that inherit the object. This selection is cleared by default, which means administrators can override the settings for any device group that inherits the object.
      Protocol
      Select the protocol used by the service (TCP or UDP).
      Destination Port
      Enter the destination port number (0 to 65535) or range of port numbers (port1-port2) used by the service. Multiple ports or ranges must be separated by commas. The destination port is required.
      Source Port
      Enter the source port number (0 to 65535) or range of port numbers (port1-port2) used by the service. Multiple ports or ranges must be separated by commas. The source port is optional.

      This setting applies to:
      • The time period after the first FIN packet is received (indicates that one side of the connection is attempting to close the session) but before it receives the second FIN packet (indicates that the other side of the connection is closing the session).
      • The time period before receiving an RST packet (indicating an attempt to reset the connection).
      If the timer expires, the session closes.
