Use Auto-Tagging to Automate Security Actions
Configure the firewall or Panorama to automatically tag
policy objects and automate security actions.
Auto-tagging allows the firewall or Panorama
to tag a policy object when it receives a log that matches specific
criteria and establish IP address-to-tag or user-to-tag mapping.
For example, when the firewall generates a threat log, you can configure
the firewall to tag the source IP address or source user in the
threat log with a specific tag name. You can then use these tags
to automatically populate policy objects such as dynamic user groups
or dynamic address groups, which can then be used to automate security
actions in security, authentication, or decryption policies. For
example, when you create a filter for the URL logs for yes in
the Credential Detected column, you can apply
a tag to the user that enforces an authentication policy that requires
user to authenticate using multi-factor authentication (MFA).
Dynamic
user groups do not support auto-tagging from HIP Match logs.
Redistribute
the mappings across your network by registering the IP address-to-tag
and user-to-tag mappings to a PAN-OS integrated User-ID agent on the
firewall or Panorama or to a remote User-ID agent using an HTTP
server profile. The firewall can automatically remove (unregister)
a tag associated with an IP address or user when you configure a
timeout as part of a built-in action for a log forwarding profile
or as part of log forwarding settings. For example, if the firewall detects
a user has potentially compromised credentials, you could configure
the firewall to require MFA authentication for that user for a given
period of time, then configure a timeout to remove the user from
the MFA requirement group.
- Depending on the type of log you want to use for tagging,
create a log forwarding profile or
configure the log settings to define
how you want the firewall or Panorama to handle logs.
- For Authentication, Data, Threat, Traffic, Tunnel Inspection, URL, and WildFire logs, create a log forwarding profile.
- For User-ID, GlobalProtect, and IP-Tag logs, configure the log settings.
- Define the match list criteria that determine when the
firewall or Panorama adds the tag to the policy object. For example, you can use a filter to configure a threshold or define a value (such as user eq “unknown” to identify users that the firewall has not yet mapped); when the firewall reaches that threshold or finds that value, the firewall adds the tag.
- To create a log forwarding profile, Add it and select the Log Type you want to monitor for match list criteria ().
- To configure log settings, Add the log settings for the type of log you want to monitor for match list criteria ().
- Copy and paste a Filter value or use the Filter Builder to define the match criteria for the tag.
- (Remote User-ID only) Configure an HTTP server
profile to forward logs to a remote User-ID agent.
- Select .
- Add a profile and specify a Name for the server profile.
- (Virtual systems only) Select the Location. The profile can be Shared across all virtual systems or can belong to a specific virtual system.
- Select Tag Registration to enable the firewall to register the IP address and tag mapping with the User-ID agent on a remote firewall. With tag registration enabled, you cannot specify the payload format.
- Add the server connection details
to access the remote User-ID agent and click OK.
- Select the log forwarding profile you created then select this server profile as the HTTP server profile for your Remote User-ID tag Registration.
- Define the policy objects to which you want to apply
the tags.
- Create or select one of the following policy objects: dynamic address groups, Use Dynamic User Groups in Policy, addresses, address groups, zones, policy rules, services, or service groups.
- Enter the tags you want to apply to the object as
the Match criteria. Confirm that the tag is identical to the tag in Step 4.
- Add the tagged policy objects to your policy. This workflow uses a Security policy as an example, but you can also use tagged policy objects in Authentication policy.
- Select .
- Click Add and enter a Name and optionally a Description for the policy.
- Add the Source Zone where the traffic originates.
- Add the Destination Zone where the traffic terminates.
- Select the Source object you created in Step 5.1.
- Select whether the rule will Allow or Deny the traffic.
- If you configured a log forwarding profile, assign it
to your Security policy. You can assign one log forwarding profile for each policy but you can assign multiple methods and actions per profile. For an example, refer to Use Dynamic Address Groups in Policy.
- Commit your changes.
- (Optional) Configure a timeout to remove the tag from
the policy object after the specified time has elapsed. Specify the amount of time (in minutes) that passes before the firewall removes the tag from the policy object. The range is from 0 to 43,200. If you set the timeout to zero, the IP address-to-tag mapping does not timeout and must be removed with an explicit action. If you set the timeout to the maximum of 43,200 minutes, the firewall removes the tag after 30 days.You cannot configure a Timeout with a Remove Tag action.
- Select the log forwarding profile.
- Add or edit one of the Built-in Actions.
- Specify the Timeout (in minutes). When
the specified time has elapsed, the firewall or Panorama removes
the tag. Set the IP-tag timeout to the same amount of time as the DHCP lease timeout for that IP address. This allows the IP address-to-tag mapping to expire at the same time as the DHCP lease so that you do not unintentionally apply policy when the IP address is reassigned.
- Click OK and Commit your changes.
