Technical preview
This functionality may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but technical preview features are not subject to the support service level agreement of official generally available features.
What is an Elastic integration?

This integration is powered by Elastic Agent. Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to our documentation for a detailed comparison between Beats and Elastic Agent.

Prefer to use Beats for this use case? See Filebeat modules for logs or Metricbeat modules for metrics.

This integration ingests and parses logs from Barracuda CloudGen Firewalls.

Barracuda CloudGen Firewall allows you to stream event logs from Firewall Insights to Elastic Agent. This provides information on firewall activity, threat logs, and information related to network, version, and location of managed firewall units. Data is sent to Elastic Agent over a TCP connection using CloudGen Firewall's built-in generic Logstash output.

Setup

For a detailed walk-through of the setup steps the see How to Enable Filebeat Stream to a Logstash Pipeline. These steps were written with a Logstash server as the intended destination, and where it references the "Hostname" use the address and port of the Elastic Agent that is running this integration. Logstash is not used as part of this integration.

Logs

Exported fields

FieldDescriptionType
@timestamp
Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events.
date
barracuda_cloudgen_firewall.log.app_rule
application rule name (e.g. "<App>:ALL-APPS")
keyword
barracuda_cloudgen_firewall.log.fw_info
Detailed information about the action performed by the firewall. More information can be found here
long
barracuda_cloudgen_firewall.log.traffic_type

constant_keyword
data_stream.namespace
Data stream namespace.
constant_keyword
data_stream.type
Data stream type.
constant_keyword
destination.address

keyword
destination.as.number
Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet.
long
destination.as.organization.name
Organization name.
keyword
destination.as.organization.name.text
Multi-field of destination.as.organization.name.
match_only_text
destination.bytes
Bytes sent from the destination to the source.
long
destination.domain
The domain name of the destination system. This value may be a host name, a fully qualified domain name, or another host naming format. The value may derive from the original event or be added from enrichment.
keyword
destination.geo.city_name
City name.
keyword
destination.geo.continent_name
Name of the continent.
keyword
destination.geo.country_iso_code
Country ISO code.
keyword
destination.geo.country_name
Country name.
keyword

User-defined description of a location, at the level of granularity they care about. Could be the name of their data centers, the floor number, if this describes a local physical entity, city names. Not typically used in automated geolocation.
keyword
destination.geo.region_iso_code
Region ISO code.
keyword
destination.geo.region_name
Region name.
keyword
destination.ip
IP address of the destination (IPv4 or IPv6).
ip
destination.mac
MAC address of the destination. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen.
keyword
destination.nat.ip
Translated ip of destination based NAT sessions (e.g. internet to private DMZ) Typically used with load balancers, firewalls, or routers.
ip
destination.packets
Packets sent from the destination to the source.
long
destination.port

long
ecs.version
ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events.
keyword
error.message
Error message.
match_only_text
event.action
The action captured by the event. This describes the information in the event. It is more specific than event.category. Examples are group-add, process-started, file-created. The value is normally defined by the implementer.
keyword
event.code
Identification code for this event, if one exists. Some event sources use event codes to identify messages unambiguously, regardless of message language or wording adjustments over time. An example of this is the Windows Event ID.
keyword
event.dataset
Event dataset
constant_keyword
event.ingested
Timestamp when an event arrived in the central data store. This is different from @timestamp, which is when the event originally occurred. It's also different from event.created, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested.
date
event.module
Event module
constant_keyword
event.original
Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source. If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference.
keyword
event.outcome
This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info, or any events for which an outcome does not make logical sense.
keyword
event.timezone
This field should be populated when the event's timestamp does not include timezone information already (e.g. default Syslog timestamps). It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00").
keyword
http.request.body.bytes
Size in bytes of the request body.
long
http.request.bytes
Total size in bytes of the request (body and headers).
long
http.request.method
HTTP request method. The value should retain its casing from the original event. For example, GET, get, and GeT are all considered valid values for this field.
keyword
http.request.mime_type
Mime type of the body of the request. This value must only be populated based on the content of the request body, not on the Content-Type header. Comparing the mime type of a request with the request's Content-Type header can be helpful in detecting threats or misconfigured clients.
keyword
http.request.referrer
Referrer for this HTTP request.
keyword
http.response.body.bytes
Size in bytes of the response body.
long
http.response.bytes
Total size in bytes of the response (body and headers).
long

keyword
labels.origin_client_subject
Distinguished name of subject of the x.509 certificate presented by the origin client when mutual TLS is enabled.
keyword
log.level
Original log level of the log event. If the source of the event provides a log level or textual severity, this is the one that goes in log.level. If your source doesn't specify one, you may put your event transport's severity here (e.g. Syslog severity). Some examples are warn, err, i, informational.
keyword
message
For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event. If multiple messages exist, they can be combined into one message.
match_only_text
