AWS Network Firewall

This integration is used to fetch logs and metrics from AWS Network Firewall—a network protections service for Amazon VPCs.

Use the AWS Network Firewall integration to monitor the traffic entering and passing through your AWS Network Firewall. Then visualize that data in Kibana, create alerts to notify you if something goes wrong, and reference logs and metrics when troubleshooting an issue.

For example, you could use this integration to view and track when firewall rules are triggered, the top firewall source and destination countries, and the total number of events by firewall.

IMPORTANT: Extra AWS charges on AWS API requests will be generated by this integration. Please refer to the AWS integration for more details.

Data streams

The AWS Network Firewall integration collects two types of data: logs and metrics.

Logs help you keep a record of events happening in AWS Network Firewall. Logs collected by the AWS Network Firewall integration include the observer name, source and destination IP, port, country, event type, and more. See more details in the Logs reference.

Metrics give you insight into the state of Network Firewall. Metrics collected by the AWS Network Firewall integration include the number of packets received, passed, and blocked by the AWS Network Firewall, and more. See more details in the Metrics reference.

Requirements

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.

Before using any AWS integration you will need:

  • AWS Credentials to connect with your AWS account.
  • AWS Permissions to make sure the user you're using to connect has permission to share the relevant data.

For more details about these requirements, please take a look at the AWS integration documentation.

Setup

Use this integration if you only need to collect data from the AWS Network Firewall service.

If you want to collect data from two or more AWS services, consider using the AWS integration. When you configure the AWS integration, you can collect data from as many AWS services as you'd like.

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

Advanced options

CloudWatch

The CloudWatch logs input has several advanced options to fit specific use cases.

Latency

AWS CloudWatch Logs sometimes takes extra time to make the latest logs available to clients like the Agent.

The CloudWatch integration offers the latency setting to address this scenario. Latency translates the query's time range to consider the CloudWatch Logs latency. For example, a 5m latency means the integration will query CloudWatch for logs available 5 minutes ago.

Number of workers

If you are collecting log events from multiple log groups using log_group_name_prefix, you should review the value of the number_of_workers.

The number_of_workers setting defines the number of workers assigned to reading from log groups. Each log group matching the log_group_name_prefix requires a worker to keep log ingestion as close to real-time as possible. For example, if log_group_name_prefix matches five log groups, then number_of_workers should be set to 5. The default value is 1.

Logs reference

The firewall_logs dataset collects AWS Network Firewall logs. Users can use these logs to monitor network activity.

An example event for firewall looks as following:

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.region_name Region name. keyword
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.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.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.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.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.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.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
group.id Unique identifier for the group on the system/platform. keyword
group.name Name of the group. 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. 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
host.name Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. keyword
host.os.build OS build information. keyword
host.os.codename OS codename, if any. keyword
host.os.family OS family (such as redhat, debian, freebsd, windows). keyword
host.os.kernel Operating system kernel version as a raw string. keyword
host.os.name Operating system name, without the version. keyword
host.os.name.text Multi-field of host.os.name. match_only_text
host.os.platform Operating system platform (such centos, ubuntu, windows). keyword
host.os.version Operating system version as a raw string. keyword
host.type Type of host. For Cloud providers this can be the machine type like t2.medium. If vm, this could be the container, for example, or other information meaningful in your environment. 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.version HTTP version. 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.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.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
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
rule.category A categorization value keyword used by the entity using the rule for detection of this event. keyword
rule.id A rule ID that is unique within the scope of an agent, observer, or other entity using the rule for detection of this event. keyword
rule.name The name of the rule or signature generating the event. keyword
source.address Some event source 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
source.as.number Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet. long
source.as.organization.name Organization name. keyword
source.as.organization.name.text Multi-field of source.as.organization.name. match_only_text
source.geo.city_name City name. keyword
source.geo.continent_name Name of the continent. keyword

source.geo.region_iso_code Region ISO code. keyword
source.geo.region_name Region name. keyword
source.ip IP address of the source (IPv4 or IPv6). ip
source.port Port of the source. long
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.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.path Path of the request, such as "/search". wildcard
url.scheme Scheme of the request, such as "https". Note: The : is not part of the scheme. keyword
