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.

Exported fields
Field | Description | Type |
---|---|---|
@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 | Always "0" | long |
barracuda_cloudgen_firewall.log.user_type | User type of web log. 1 if "user" is a username or 0 if "user" is an IP address. | keyword |
data_stream.dataset | Data stream dataset. | constant_keyword |
data_stream.namespace | Data stream namespace. | constant_keyword |
data_stream.type | Data stream type. | constant_keyword |
destination.address | Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain , depending on which one it is. | 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 |
destination.geo.location | Longitude and latitude. | geo_point |
destination.geo.name | 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 | Port of the destination. | 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 |
http.response.status_code | HTTP response status code. | long |
http.version | HTTP version. | keyword |
input.type | Type of Filebeat input. | keyword |
labels | Custom key/value pairs. Can be used to add meta information to events. Should not contain nested objects. All values are stored as keyword. Example: docker and k8s labels. | object |
labels.origin_address | Remote address where the log originated. | 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 |
network.community_id | A hash of source and destination IPs and ports, as well as the protocol used in a communication. This is a tool-agnostic standard to identify flows. Learn more at https://github.com/corelight/community-id-spec. | keyword |
network.iana_number | IANA Protocol Number (https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml). Standardized list of protocols. This aligns well with NetFlow and sFlow related logs which use the IANA Protocol Number. | keyword |
network.transport | Same as network.iana_number, but instead using the Keyword name of the transport layer (udp, tcp, ipv6-icmp, etc.) The field value must be normalized to lowercase for querying. | keyword |
network.type | In the OSI Model this would be the Network Layer. ipv4, ipv6, ipsec, pim, etc The field value must be normalized to lowercase for querying. | keyword |
observer.egress.interface.name | Interface name as reported by the system. | keyword |
observer.hostname | Hostname of the observer. | keyword |

In this case, the IP address would go to the domain field. If the URL contains a literal IPv6 address enclosed by [ and ] (IETF RFC 2732), the [ and ] characters should also be captured in the domain field. | keyword |
url.extension | The field contains the file extension from the original request url, excluding the leading dot. The file extension is only set if it exists, as not every url has a file extension. The leading period must not be included. For example, the value must be "png", not ".png". Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz"). | keyword |
