This integration is for Barracuda device's logs. It includes the following datasets for receiving logs over syslog or read from a file:

waf dataset: supports Barracuda Web Application Firewall logs.

Use the Barracuda WAF data stream to ingest log data. Then visualize that data in Kibana, create alerts to notify you if something goes wrong, and reference data_stream.dataset:barracuda.waf when troubleshooting an issue.

Upgrade

The Technical preview spamfirewall data stream has been deprecated and removed, as of v1.0 of this integration. As we work on a replacement for the Spam Firewall integration, you can continue to use the Spam Firewall filebeat module.

WAF

Barracuda Web Application Firewall protects applications, APIs, and mobile app backends against a variety of attacks including the OWASP Top 10, zero-day threats, data leakage, and application-layer denial of service (DoS) attacks. By combining signature-based policies and positive security with robust anomaly-detection capabilities, Barracuda Web Application Firewall can defeat today’s most sophisticated attacks targeting your web applications.

Requirements

This integration is built and tested against the Barracuda Web Application Firewall version 12.1. Earlier versions may work, but have not been tested.

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.

Setup

For step-by-step instructions on how to set up an integration, see the Getting started guide.

WAF Events

The barracuda.waf dataset provides events from the configured syslog server. All Barracuda WAF syslog specific fields are available in the barracuda.waf field group.

An example event for waf looks as following:

destination.ip	IP address of the destination (IPv4 or IPv6).	ip
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.category	This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories.	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.created	`event.created` contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from `@timestamp` in that `@timestamp` typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, `@timestamp` should be used.	date
event.duration	Duration of the event in nanoseconds. If `event.start` and `event.end` are known this value should be the difference between the end and start time.	long
event.end	`event.end` contains the date when the event ended or when the activity was last observed.	date
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.kind	This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not.	keyword
event.provider	Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing).	keyword
event.severity	The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`.	long
event.start	`event.start` contains the date when the event started or when the activity was first observed.	date
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
event.type	This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types.	keyword
file.path	Full path to the file, including the file name. It should include the drive letter, when appropriate.	keyword
file.path.text	Multi-field of `file.path`.	match_only_text
http.request.bytes	Total size in bytes of the request (body and headers).	long
http.request.id	A unique identifier for each HTTP request to correlate logs between clients and servers in transactions. The id may be contained in a non-standard HTTP header, such as `X-Request-ID` or `X-Correlation-ID`.	keyword
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.referrer	Referrer for this HTTP request.	keyword
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	Input type	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
log.file.path	Full path to the log file this event came from, including the file name. It should include the drive letter, when appropriate. If the event wasn't read from a log file, do not populate this field.	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
log.offset	Log offset	long
log.source.address	Source address from which the log event was read / sent from.	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.bytes	Total bytes transferred in both directions. If `source.bytes` and `destination.bytes` are known, `network.bytes` is their sum.	long
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.direction	Direction of the network traffic. When mapping events from a host-based monitoring context, populate this field from the host's point of view, using the values "ingress" or "egress". When mapping events from a network or perimeter-based monitoring context, populate this field from the point of view of the network perimeter, using the values "inbound", "outbound", "internal" or "external". Note that "internal" is not crossing perimeter boundaries, and is meant to describe communication between two hosts within the perimeter. Note also that "external" is meant to describe traffic between two hosts that are external to the perimeter. This could for example be useful for ISPs or VPN service providers.	keyword
network.forwarded_ip	Host IP address when the source IP address is the proxy.	ip
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.inner	Network.inner fields are added in addition to network.vlan fields to describe the innermost VLAN when q-in-q VLAN tagging is present. Allowed fields include vlan.id and vlan.name. Inner vlan fields are typically used when sending traffic with multiple 802.1q encapsulations to a network sensor (e.g. Zeek, Wireshark.)	group
network.inner.vlan.id	VLAN ID as reported by the observer.	keyword
network.inner.vlan.name	Optional VLAN name as reported by the observer.	keyword
network.protocol	In the OSI Model this would be the Application Layer protocol. For example, `http`, `dns`, or `ssh`. The field value must be normalized to lowercase for querying.	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.egress.zone	Network zone of outbound traffic as reported by the observer to categorize the destination area of egress traffic, e.g. Internal, External, DMZ, HR, Legal, etc.	keyword

observer.ingress.interface.name	Interface name as reported by the system.	keyword
observer.ingress.zone	Network zone of incoming traffic as reported by the observer to categorize the source area of ingress traffic. e.g. internal, External, DMZ, HR, Legal, etc.	keyword
observer.ip	IP addresses of the observer.	ip
observer.name	Custom name of the observer. This is a name that can be given to an observer. This can be helpful for example if multiple firewalls of the same model are used in an organization. If no custom name is needed, the field can be left empty.	keyword
observer.product	The product name of the observer.	keyword
observer.type	The type of the observer the data is coming from. There is no predefined list of observer types. Some examples are `forwarder`, `firewall`, `ids`, `ips`, `proxy`, `poller`, `sensor`, `APM server`.	keyword
observer.vendor	Vendor name of the observer.	keyword
observer.version	Observer version.	keyword

rule.description	The description of the rule generating the event.	keyword
rule.name	The name of the rule or signature generating the event.	keyword
server.address	Some event server 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
server.domain	The domain name of the server 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

url.domain	Domain of the url, such as "www.elastic.co". In some cases a URL may refer to an IP and/or port directly, without a domain name. 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
url.fragment	Portion of the url after the `#`, such as "top". The `#` is not part of the fragment.	keyword
url.full	If full URLs are important to your use case, they should be stored in `url.full`, whether this field is reconstructed or present in the event source.	wildcard
url.full.text	Multi-field of `url.full`.	match_only_text
url.original	Unmodified original url as seen in the event source. Note that in network monitoring, the observed URL may be a full URL, whereas in access logs, the URL is often just represented as a path. This field is meant to represent the URL as it was observed, complete or not.	wildcard
url.original.text	Multi-field of `url.original`.	match_only_text
url.password	Password of the request.	keyword
url.path	Path of the request, such as "/search".	wildcard
url.port	Port of the request, such as 443.	long
url.query	The query field describes the query string of the request, such as "q=elasticsearch". The `?` is excluded from the query string. If a URL contains no `?`, there is no query field. If there is a `?` but no query, the query field exists with an empty string. The `exists` query can be used to differentiate between the two cases.	keyword
url.registered_domain	The highest registered url domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk".	keyword
url.scheme	Scheme of the request, such as "https". Note: The `:` is not part of the scheme.	keyword
url.subdomain	The subdomain portion of a fully qualified domain name includes all of the names except the host name under the registered_domain. In a partially qualified domain, or if the the qualification level of the full name cannot be determined, subdomain contains all of the names below the registered domain. For example the subdomain portion of "www.east.mydomain.co.uk" is "east". If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period.	keyword
url.top_level_domain	The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk".	keyword
