Balancer

Specifies the address for connection to Balancer.

The value can be an IPv4 address, an IPv6 address, or a hostname.

The following parameters must be specified:

• matching_port—The port on which Balancer receives incoming events. The range of values for this parameter is from 1 to 65535. This parameter is mandatory.
• api_port—The port on which Balancer accepts API requests. The range of values for this parameter is from 1 to 65535. This parameter is mandatory.
• cybertrace_port—The port on which Balancer receives alert events from Kaspersky CyberTrace instances. The range of values for this parameter is from 1 to 65535. This parameter is mandatory.
• scanners_count—The maximum number of simultaneous connections. The range of values for this parameter is from 1 to 100. This parameter is mandatory.

This element is mandatory. The configuration file can contain only one Balancer element.

EventDelimiter

The regular expression that defines the delimiter for events.

This element is optional.

If an event contains newline characters (\n), such an event will be split by using both the value of this element and newline characters as event delimiters.

SSLCertificatePath

The path to the PEM-formatted certificate for HTTPS connections.

This element can contain an absolute or a relative path. If a relative path is specified, it is calculated relative to the Balancer binary file.

This parameter is optional. The default value is:

• On Windows systems:

  ..\httpsrv\kl_feed_service_cert.pem.

• On Linux systems:

  ../httpsrv/kl_feed_service_cert.pem.

Update the value of this element if Balancer is deployed on a computer without Kaspersky CyberTrace.

SSLPrivateKeyPath

The path to the PEM-formatted private key for HTTPS connections.

This element can contain an absolute or a relative path. If a relative path is specified, it is calculated relative to the Balancer binary file.

This parameter is optional. The default value is:

• On Windows systems:

  ..\httpsrv\kl_feed_service_private.pem.

• On Linux systems:

  ../httpsrv/kl_feed_service_private.pem.

Update the value of this element if Balancer is deployed on a computer without Kaspersky CyberTrace.

LicenseDirPath

The path to the directory with a license key file.

This element can contain an absolute or a relative path. If a relative path is specified, it is calculated relative to the Balancer binary file.

This parameter is optional. The default value is:

• On Windows systems:

  ..\httpsrv\lic.

• On Linux systems:

  ../httpsrv/lic.

Update the value of this element if Balancer is deployed on a computer without Kaspersky CyberTrace.

OutputSettings

Specifies the address for sending the results of incoming events matching.

The value can be an IPv4 address, an IPv6 address, or a hostname.

The following parameter can be specified:

• port—The port to which Balancer sends the results of incoming events matching. The range of values for this parameter is from 1 to 65535. This parameter is mandatory.

This element is mandatory.

Instances

The section that contains elements with parameters of Kaspersky CyberTrace instances.

The following parameters can be specified for the section:

• update_seconds—The time interval, in seconds, between attempts to connect to inaccessible instances of Kaspersky CyberTrace.

  This parameter is mandatory. The range of values for this parameter is from 1 to 3600.

• matching_timeout_seconds—The timeout, in seconds, for the response from an instance of Kaspersky CyberTrace with the result of incoming event matching.

  This parameter is mandatory. The range of values for this parameter is from 1 to 3600.

• api_timeout_seconds—The timeout, in seconds, for the response from an instance of Kaspersky CyberTrace to a REST API request.

  This parameter is mandatory. The range of values for this parameter is from 1 to 3600.

This element is mandatory.

Instances/Instance

An element with parameters for connection to an instance of Kaspersky CyberTrace.

The value can be an IPv4 or IPv6 address.

This element is mandatory.

The following parameters can be specified:

• enabled—Specifies the state of the Kaspersky CyberTrace instance.

  This parameter is mandatory.

  Use true or false as a value for this parameter.

• matching_port—The port on which the Kaspersky CyberTrace instance accepts incoming events.

  The value of this parameter must be similar to the value of the InputSettings > ConnectionString element in the configuration file of the Kaspersky CyberTrace instance.

  This parameter is mandatory.

  The range of values for this parameter is from 1 to 65535.

• api_port—The port on which the Kaspersky CyberTrace instance accepts REST API requests.

  The value of this parameter must be similar to the value of the HTTPServer > ConnectionString element in the configuration file of the Kaspersky CyberTrace instance.

  This parameter is mandatory.

  The range of values for this parameter is from 1 to 65535.

• scanners_count—The maximum number of simultaneous connections allowed for the Kaspersky CyberTrace instance.

  This parameter is mandatory. The range of values for this parameter is from 1 to 100.

  The value of the scanners_count parameter of a Kaspersky CyberTrace instance must not exceed the value, less 1, of the ScannersCount parameter specified in the configuration file of that Kaspersky CyberTrace instance.

This element is mandatory.

AllowedRequests

The section that contains elements with parameters of allowed REST API requests to Kaspersky CyberTrace instances.

This element is mandatory.

AllowedRequests/AllowedRequest

An element with parameters of an allowed REST API request to Kaspersky CyberTrace instances.

This element is optional.

This element can contain a string that is from 1 to 2048 characters long and contains only ASCII characters.

The value of this element can contain the '*' wildcard character, which stands for zero or any number of any characters.

The following parameter can be specified:

• method—The request method. Use GET, POST, PUT, or DELETE as a value for this parameter.

  This parameter is mandatory. The value of this parameter is not case-sensitive.

By default, kl_balancer.conf contains all necessary AllowedRequest elements for using the REST API of Kaspersky CyberTrace.
