to each session. |
Repeat Count (repeatcnt) | Number of sessions with same Source IP,
Destination IP, Application, and Content/Threat Type seen within
5 seconds. |
Source Port (sport) | Source port utilized by the session. |
Destination Port (dport) | Destination port utilized by the session. |
NAT Source Port (natsport) | Post-NAT source port. |
NAT Destination Port (natdport) | Post-NAT destination port. |
Flags (flags) | 32-bit field that provides details on session;
this field can be decoded by AND-ing the values with the logged
value:
|
IP Protocol (proto) | IP protocol associated with the session. |
Action (action) | Action taken for the session; values are
alert, allow, deny, drop, drop-all-packets, reset-client, reset-server,
reset-both, block-url.
|
URL/Filename (misc) | Field with variable length. A Filename has
a maximum of 63 characters. File name when the subtype is
dlp |
Threat/Content Name (threatid) | Palo Alto Networks identifier for known
and custom threats. It is a description string followed by a 64-bit
numerical identifier in parentheses for some Subtypes:
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:
|
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:
|
Virtual System Name (vsys_name) | The name of the virtual system associated
with the session; only valid on firewalls enabled for multiple virtual
systems. |
Device Name (device_name) | The hostname of the firewall on which the
session was logged. |
Source VM UUID (src_uuid) | Identifies the source universal unique identifier
for a guest virtual machine in the VMware NSX environment. |
Destination VM UUID (dst_uuid) | Identifies the destination universal unique
identifier for a guest virtual machine in the VMware NSX environment. |
HTTP Method (http_method) | Only in URL filtering logs. Describes the
HTTP Method used in the web request. Only the following methods
are logged: Connect, Delete, Get, Head, Options, Post, Put. |
Tunnel ID/IMSI (tunnel_id/imsi) | International Mobile Subscriber
Identity (IMSI) is a unique number allocated to each mobile subscriber
in the GSM/UMTS/EPS system. IMSI shall consist of decimal digits
(0 through 9) only and maximum number of digits allowed are 15. |
Monitor Tag/IMEI (monitortag/imei) | International Mobile Equipment
Identity (IMEI) is a unique 15 or 16 digit number allocated to each
mobile station equipment. |
Parent Session ID (parent_session_id) | ID of the session in which this session
is tunneled. Applies to inner tunnel (if two levels of tunneling)
or inside content (if one level of tunneling) only. |
Parent Session Start Time (parent_start_time) | Year/month/day hours:minutes:seconds that
the parent tunnel session began. |
Tunnel Type (tunnel) | Type of tunnel, such as GRE or IPSec. |
Threat Category (thr_category) | Describes threat categories used to classify
different types of threat signatures. If a domain external dynamic list generated
the log, domain-edl populates this
field. |
Content Version (contentver) | Applications and Threats version
on your firewall when the log was generated. |
SCTP Association ID (assoc_id) | Number that identifies all connections for
an association between two SCTP endpoints. |
Payload Protocol ID (ppid) | ID of the protocol for the payload in the
data portion of the data chunk. |
HTTP Headers (http_headers) | Indicates the inserted HTTP header in the
URL log entries on the firewall. |
URL Category List (url_category_list) | Lists the URL Filtering categories that
the firewall used to enforce policy. |
Rule UUID (rule_uuid) | The UUID that permanently identifies the
rule. |
(http2_connection) | Identifies if traffic used an HTTP/2 connection
by displaying one of the following values:
|
Dynamic User Group Name (dynusergroup_name) | The name of the dynamic user group that
contains the user who initiated the session. |
