Cisco FTD

Collect logs from Cisco FTD with Elastic Agent.

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 is for Cisco Firepower Threat Defence (FTD) device's logs. The package processes syslog messages from Cisco Firepower devices

It includes the following datasets for receiving logs over syslog or read from a file:

  • log dataset: supports Cisco Firepower Threat Defense (FTD) logs.

Configuration

Cisco provides a range of Firepower devices, which may have different configuration steps. We recommend users navigate to the device specific configuration page, and search for/go to the "FTD Logging" or "Configure Logging on FTD" page for the specific device.

Logs

FTD

The log dataset collects the Cisco Firepower Threat Defense (FTD) logs.

An example event for log looks as following:

match_only_text
dns.question.name
The name being queried. If the name field contains non-printable characters (below 32 or above 126), those characters should be represented as escaped base 10 integers (\DDD). Back slashes and quotes should be escaped. Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively.
keyword
dns.question.registered_domain
The highest registered 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
dns.question.subdomain
The subdomain is all of the labels under the registered_domain. 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
dns.question.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
dns.question.type
The type of record being queried.
keyword
dns.response_code
The DNS response code.
keyword
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.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.dataset
Event dataset
constant_keyword
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 coming in at a regular interval or not.
keyword
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.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.reason
Reason why this event happened, according to the source. This describes the why of a particular action or outcome captured in the event. Where event.action captures the action from the event, event.reason describes why that action was taken. For example, a web proxy with an event.action which denied the request may also populate event.reason with the reason why (e.g. blocked site).
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.hash.sha256
SHA256 hash.
keyword
file.name
Name of the file including the extension, without the directory.
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
file.size

long
host.architecture
Operating system architecture.
keyword
host.containerized
If the host is a container.
boolean
host.domain
Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider.
keyword
host.hostname
Hostname of the host. It normally contains what the hostname command returns on the host machine.
keyword
host.id
Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name.
keyword
host.ip
Host ip addresses.
ip
host.mac
Host mac addresses.
keyword
host.name
Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use.
keyword

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
Offset of the entry in the log file.
long
log.source.address
Source address from which the log event was read / sent from.
keyword
log.syslog.facility.code
The Syslog numeric facility of the log event, if available. According to RFCs 5424 and 3164, this value should be an integer between 0 and 23.
long
log.syslog.priority
Syslog numeric priority of the event, if available. According to RFCs 5424 and 3164, the priority is 8 * facility + severity. This number is therefore expected to contain a value between 0 and 191.
long
log.syslog.severity.code
The Syslog numeric severity of the log event, if available. If the event source publishing via Syslog provides a different numeric severity value (e.g. firewall, IDS), your source's numeric severity should go to event.severity. If the event source does not specify a distinct severity, you can optionally copy the Syslog severity to event.severity.
long
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.application
When a specific application or service is identified from network connection details (source/dest IPs, ports, certificates, or wire format), this field captures the application's or service's name. For example, the original event identifies the network connection being from a specific web service in a https network connection, like facebook or twitter. The field value must be normalized to lowercase for querying.
keyword
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
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

keyword
related.hosts
All hostnames or other host identifiers seen on your event. Example identifiers include FQDNs, domain names, workstation names, or aliases.
keyword
related.ip
All of the IPs seen on your event.
ip
related.user
All the user names or other user identifiers seen on 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.

long
server.user.name
Short name or login of the user.
keyword
server.user.name.text

match_only_text
service.id
Unique identifier of the running service. If the service is comprised of many nodes, the service.id should be the same for all nodes. This id should uniquely identify the service. This makes it possible to correlate logs and metrics for one specific service, no matter which particular node emitted the event. Note that if you need to see the events from one specific host of the service, you should filter on that host.name or host.id instead.
keyword
source.address

tags
List of keywords used to tag each event.
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

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".

user.email
User email address.
keyword
user.id
Unique identifier of the user.
keyword
user.name
