The Elastic integration for DNS Server logs is designed to facilitate the collection, aggregation, and analysis of DNS logs from both Audit and Analytical categories. By capturing detailed DNS event data, this integration enables organizations to enhance their visibility into DNS transactions, detect potential security threats, and optimize their network performance. Leveraging the powerful capabilities of Elastic Stack, this integration provides real-time insights and analytics, empowering IT and security teams to quickly respond to incidents and maintain robust network infrastructure integrity.

Data streams

edit

The Microsoft DNS Server integration collects two type of data: audit and analytical.

Analytical events represent the bulk of DNS events, an analytic event is logged each time the server sends or receives DNS information.

Audit events enable change tracking on the DNS server. An audit event is logged each time server, zone, or resource record settings are changed. This includes operational events such as dynamic updates, zone transfers, and DNSSEC zone signing and unsigning.

Requirements

edit

Elastic Agent must be installed.
You can install only one Elastic Agent per host.

Installing and managing an Elastic Agent:

edit

You have a few options for installing and managing an Elastic Agent:

Install a Fleet-managed Elastic Agent (recommended):

edit

With this approach, you install Elastic Agent and use Fleet in Kibana to define, configure, and manage your agents in a central location. We recommend using Fleet management because it makes the management and upgrade of your agents considerably easier.

Install Elastic Agent in standalone mode (advanced users):

edit

With this approach, you install Elastic Agent and manually configure the agent locally on the system where it’s installed. You are responsible for managing and upgrading the agents. This approach is reserved for advanced users only.

Install Elastic Agent in a containerized environment:

edit

You can run Elastic Agent inside a container, either with Fleet Server or standalone. Docker images for all versions of Elastic Agent are available from the Elastic Docker registry, and we provide deployment manifests for running on Kubernetes.

There are some minimum requirements for running Elastic Agent and for more information, refer to the link here.

This integration is supported in every Windows versions supported by Filebeat, starting from Windows 10 and Windows Server 2016.

The minimum kibana.version required is 8.13.0.

Configuration

edit

DNS analytical events are not enabled by default. To enable it, you can follow the guide to enable DNS diagnostics logging of Microsoft’s documentation.

DNS logging and diagnostics feature in Windows is designed to have a very low impact on performance. However, according to the Audit and analytic event logging section of the docs, typically will only affect DNS server performance at very high DNS query rates. For example, a DNS server running on modern hardware that is receiving 100,000 queries per second (QPS) can experience a performance degradation of 5% when analytic logs are enabled.

Usage

edit

DNS Analytical events are collected through Event Tracing for Windows (ETW), a mechanism that allows real-time logging and capturing of Windows system events. This collection can be done either by initiating a new ETW session to gather logs directly from the DNS Server provider or by reading pre-existing logs from a .etl (Event Trace Log) file.

This integration provides a native filtering mechanism called Match All Keyword. This filter uses a 64-bit bitmask to specify which events to capture based on their defined keywords. Each keyword corresponds to a specific type of event detailed in the DNS Server provider’s manifest.

To view these keywords and understand what types of events can be traced, you can run the following command in a command prompt: logman query providers "Microsoft-Windows-DNSServer". Here is an example of the output:

PS> logman query providers "Microsoft-Windows-DNSServer"

The command completed successfully.

The output lists various event types with corresponding keywords, allowing you to select which events to monitor. For example, if you want to track recursive queries, you would look for keywords like RECURSE_QUERY_OUT, RECURSE_RESPONSE_IN, and RECURSE_QUERY_DROP. To set up filtering for these specific events, you would calculate the sum of their bitmask values. The result for this particular case would be 0x8000000000000070 (notice that it includes 0x8000000000000000 to match Analytical events as well).

On the other hand, Audit events are exposed through Microsoft-Windows-DNS-Server/Audit event log channel.

destination.port	Port of the destination.	long
dns.header_flags	Array of 2 letter DNS header flags.	keyword
dns.id	The DNS packet identifier assigned by the program that generated the query. The identifier is copied to the response.	keyword
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.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
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.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.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.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
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`.	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
input.type	Input type.	keyword
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
microsoft_dnsserver.analytical.additional_info	Any additional information relevant to the event.	keyword
microsoft_dnsserver.analytical.bytes_sent	The number of bytes sent in the DNS response.	long

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.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

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.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
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
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
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`.	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
input.type	Input type.	keyword
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
