This module has been developed against Snort v2.9 and v3, but is expected to work with other versions of Snort. This package is designed to read from the PFsense CSV output, the Alert Fast output either via reading a local logfile or receiving messages via syslog and the Snort 3 JSON log file.

Log

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.

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

Longitude and latitude.

geo_point

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.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

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.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.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.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.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.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

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

input.type

Input type

keyword

log.file.path

keyword

log.flags

Flags for the log file.

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.

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.
