Source port utilized by the session.
Session ID (sessionid)
An internal numerical identifier applied to each session.
Destination address (dst_ip)

  • alert—threat or URL detected but not blocked
  • allow— flood detection alert
  • deny—flood detection mechanism activated and deny traffic based on configuration
  • drop— threat detected and associated session was dropped
  • reset-client —threat detected and a TCP RST is sent to the client
  • reset-server —threat detected and a TCP RST is sent to the server
  • reset-both —threat detected and a TCP RST is sent to both the client and the server
  • block-url —URL request was blocked because it matched a URL category that was set to be blocked
  • block-ip—threat detected and client IP is blocked
  • random-drop—flood detected and packet was randomly dropped
  • sinkhole—DNS sinkhole activated
  • syncookie-sent—syncookie alert
  • block-continue (URL subtype only)—a HTTP request is blocked and redirected to a Continue page with a button for confirmation to proceed
  • continue (URL subtype only)—response to a block-continue URL continue page indicating a block-continue request was allowed to proceed
  • block-override (URL subtype only)—a HTTP request is blocked and redirected to an Admin override page that requires a pass code from the firewall administrator to continue
  • override-lockout (URL subtype only)—too many failed admin override pass code attempts from the source IP. IP is now blocked from the block-override redirect page
  • override (URL subtype only)—response to a block-override page where a correct pass code is provided and the request is allowed
  • block (Wildfire only)—file was blocked by the firewall and uploaded to Wildfire
Threat Category (threat_category)
Describes threat categories used to classify different types of threat signatures.
Threat/Content Type (threat_content_type)
Subtype of threat log. Values include the following:
  • data—Data pattern matching a Data Filtering profile.
  • file—File type matching a File Blocking profile.
  • flood—Flood detected via a Zone Protection profile.
  • packet—Packet-based attack protection triggered by a Zone Protection profile.
  • scan—Scan detected via a Zone Protection profile.
  • spyware —Spyware detected via an Anti-Spyware profile.
  • url—URL filtering log.
  • ml-virus—Virus detected by WildFire Inline ML via an Antivirus profile.
  • virus—Virus detected via an Antivirus profile.
  • vulnerability —Vulnerability exploit detected via a Vulnerability Protection profile.
  • wildfire —A WildFire verdict generated when the firewall submits a file to WildFire per a WildFire Analysis profile and a verdict (malware, phishing, grayware, or benign, depending on what you are logging) is logged in the WildFire Submissions log.
  • wildfire-virus—Virus detected via an Antivirus profile.
Threat/Content Name (threat_content_name)
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:
  • 8000 – 8099— scan detection
  • 8500 – 8599— flood detection
  • 9999— URL filtering log
  • 10000 – 19999 —spyware phone home detection
  • 20000 – 29999 —spyware download detection
  • 30000 – 44999 —vulnerability exploit detection
  • 52000 – 52999— filetype detection
  • 60000 – 69999 —data filtering detection
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.
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 or server-to-client:
  • 0—direction of the threat is client to server
  • 1—direction of the threat is server to client
Repeat Count (repeatcnt)
Number of sessions with same Source IP, Destination IP, Application, and Content/Threat Type seen within 5 seconds.
Reason (data_filter_reason)
Reason for Data Filtering action.
XFF Address (xff_ip)
The IP address of the user who requested the web page or the IP address of the next to last device that the request traversed. If the request goes through one or more proxies, load balancers, or other upstream devices, the firewall displays the IP address of the most recent device.
Content Version (contentver)
Applications and Threats version on your firewall when the log was generated.
