Learn More About Threat Signatures using Threat IDs

The firewall Threat logs record all threats the firewall detects based on threat signatures and the ACC displays an overview of the top threats on your network. Each event the firewall records includes an ID that identifies the associated threat signature.
Now that all threat IDs are unique, you can use the threat ID found with a Threat log or ACC entry to:
  • Easily check if a threat signature is configured as an exception to your security policy.
What is a threat exception?
Palo Alto Networks defines a default action (such as block or alert) for threat signatures; unless otherwise specified, the firewall enforces threat signatures based on the default action. However, you can create a threat exception to either exclude a threat signature from enforcement or to modify how the firewall enforces that specific signature. Learn more about and create threat exceptions.
  • Find the latest Threat Vault information about a specific threat. Because the Threat Vault is now integrated with the firewall, you can view threat details directly in the firewall context or launch a Threat Vault search in a new browser window for a threat the firewall logged.
  1. Confirm the firewall is connected to the Threat Vault.
    The firewall is now enabled to access the Threat Vault by default in order to gather the latest information about detected threats. To confirm that threat vault access is enabled after upgrading to PAN-OS 8.0, select DeviceSetupManagement and edit the Logging and Reporting setting to Enable Threat Vault Access.
  2. Find the threat ID for threats the firewall detects:
    • To see each threat event the firewall detects based on threat signatures, select MonitorLogsThreat. You can find the ID for a threat entry listed in the ID column, or select the log entry to view log details, including the Threat ID.
    • To see an overview of top threats on the network, select ACCThreat Activity and take a look at the Threat Activity widget. The ID column displays the threat ID for each threat displayed.
    • To see details for threats that you can configure as threat exceptions (meaning, the firewall enforces the threat differently than the default action defined for the threat signature), select ObjectsSecurity ProfilesAnti-Spyware/Vulnerability Protection. Add or modify a profile and click the Exceptions tab to view configured exceptions. If no exceptions are configured, you can filter for threat signatures or select Show all signatures.
  3. Hover over a Threat Name or the threat ID and click Exception to review both the threat details and how the firewall is configured to enforce the threat.
    For example, find out more about a top threat charted on the ACC:

  4. Review the latest Threat Details for the threat and launch a Threat Vault search based on the threat ID:
    • Threat details displayed include the latest Threat Vault information for the threat, resources you can use to learn more about the threat, and CVEs associated with the threat.
    • Select View in Threat Vault to open a Threat Vault search in a new window and look up the latest information the Palo Alto Networks threat database has for this threat signature.
  5. Check if a threat signature is configured as an exception to your security policy:
    • If the Used in current security rule column is clear, the firewall is enforcing the threat based on the recommended default signature action (for example, block or alert).
    • A checkmark anywhere in the Used in current security rule column indicates that a security policy rule is configured to enforce a non-default action for the threat (for example, allow), based on the associated Exempt Profiles settings.
    The Used in security rule column does not indicate if the security rule is enabled, only if the security policy rule is configured with the threat exception. Select PoliciesSecurity to check if an indicated security policy rule is enabled.
  6. Add an IP address on which to filter the threat exception or view existing Exempt IP Addresses. Configure an exempt IP address to enforce a threat exception only when the associated session has either a matching source or destination IP address; for all other sessions, the threat is enforced based on the default signature action.
