Threat ID ranges for virus detection, WildFire signature feed, and DNS C2 signatures used in previous releases have been replaced with permanent, globally unique IDs. Refer to the Threat/Content Type (subtype) and Threat Category (thr_category) field names to create updated reports, filter threat logs, and ACC activity.
Category (category)
For URL Subtype, it is the URL Category; For WildFire subtype, it is the verdict on the file and is either ‘malware’, ‘phishing’, ‘grayware’, or ‘benign’; For other subtypes, the value is ‘any’.
Severity (severity)
Severity associated with the threat; values are informational, low, medium, high, critical.
Direction (direction)
Indicates the direction of the attack:
  • client-to-server
  • server-to-client
Sequence Number (seqno)
A 64-bit log entry identifier incremented sequentially. Each log type has a unique number space.
Action Flags (actionflags)
A bit field indicating if the log was forwarded to Panorama.
Source Country (srcloc)
Source country or Internal region for private addresses. Maximum length is 32 bytes.
Destination Country (dstloc)
Destination country or Internal region for private addresses. Maximum length is 32 bytes.
Content Type (contenttype)
Applicable only when Subtype is URL.
Content type of the HTTP response data. Maximum length 32 bytes.
PCAP ID (pcap_id)
The packet capture (pcap) ID is a 64 bit unsigned integral denoting an ID to correlate threat pcap files with extended pcaps taken as a part of that flow. All threat logs will contain either a pcap_id of 0 (no associated pcap), or an ID referencing the extended pcap file.
File Digest (filedigest)
Only for WildFire subtype; all other types do not use this field
The filedigest string shows the binary hash of the file sent to be analyzed by the WildFire service.
Cloud (cloud)
Only for WildFire subtype; all other types do not use this field.
The cloud string displays the FQDN of either the WildFire appliance (private) or the WildFire cloud (public) from where the file was uploaded for analysis.
URL Index (url_idx)
Used in URL Filtering and WildFire subtypes.
When an application uses TCP keepalives to keep a connection open for a length of time, all the log entries for that session have a single session ID. In such cases, when you have a single threat log (and session ID) that includes multiple URL entries, the url_idx is a counter that allows you to correlate the order of each log entry within the single session.
For example, to learn the URL of a file that the firewall forwarded to WildFire for analysis, locate the session ID and the url_idx from the WildFire Submissions log and search for the same session ID and url_idx in your URL filtering logs. The log entry that matches the session ID and url_idx will contain the URL of the file that was forwarded to WildFire.
User Agent (user_agent)
Only for the URL Filtering subtype; all other types do not use this field.
The User Agent field specifies the web browser that the user used to access the URL, for example Internet Explorer. This information is sent in the HTTP request to the server.
File Type (filetype)
Specifies the type of file that the firewall forwarded for analysis.
X-Forwarded-For (xff)
Only for the URL Filtering subtype; all other types do not use this field.
The X-Forwarded-For field in the HTTP header contains the IP address of the user who requested the web page. It allows you to identify the IP address of the user, which is useful particularly if you have a proxy server on your network that replaces the user IP address with its own address in the source IP address field of the packet header.
Referer (referer)
Only for the URL Filtering subtype; all other types do not use this field.
The Referer field in the HTTP header contains the URL of the web page that linked the user to another web page; it is the source that redirected (referred) the user to the web page that is being requested.
Sender (sender)
Specifies the name of the sender of an email.
Subject (subject)
Specifies the subject of an email.
Recipient (recipient)
Specifies the name of the receiver of an email.
Report ID (reportid)
Identifies the analysis request on the firewall, WildFire cloud, or the WildFire appliance.
Device Group Hierarchy (dg_hier_level_1 to dg_hier_level_4)
A sequence of identification numbers that indicate the device group’s location within a device group hierarchy. The firewall (or virtual system) generating the log includes the identification number of each ancestor in its device group hierarchy. The shared device group (level 0) is not included in this structure.
If the log values are 12, 34, 45, 0, it means that the log was generated by a firewall (or virtual system) that belongs to device group 45, and its ancestors are 34, and 12. To view the device group names that correspond to the value 12, 34 or 45, use one of the following methods:
API query:
/api/?type=op&cmd=<show><dg-hierarchy></dg-hierarchy></show>
