Tcp type

Tcp type

The tcp type is used for TCP communications.

Basic settings tab

Setting	Description
Name	Required setting. Unique name of the resource. Must contain 1 to 128 Unicode characters.
Tenant	Required setting. The name of the tenant that owns the resource.
Disabled switch	Used when events must not be sent to the destination. By default, sending events is enabled.
Type	Required setting. Destination type, tcp.
URL	Required setting. URL that you want to connect to. Available formats: `<host>:<port>`, `<IPv4>:<port>`, `:<port>`. IPv6 addresses are also supported. When using IPv6 addresses, you must also specify the interface in the `[address%interface]:port` format. For example, `[fe80::5054:ff:fe4d:ba0c%eth0]:4222`).
Description	Resource description: up to 4,000 Unicode characters.

Advanced settings tab

Setting	Description
Compression	You can use Snappy compression. By default, compression is disabled.
Buffer size	Sets the size of the buffer. The default value is 1 KB, and the maximum value is 64 MB.
Timeout	The time (in seconds) to wait for a response from another service or component. The default value is `30`.
Disk buffer size limit	Size of the disk buffer in bytes. The default value is 10 GB.
TLS mode	TLS encryption mode using certificates in pem x509 format. Available values: Disabled means TLS encryption is not used. The default value. Enabled means encryption is used, but certificates are not verified. With verification means encryption is used with verification that the certificate was signed with the KUMA root certificate. The root certificate and key of KUMA are created automatically during program installation and are stored on the KUMA Core server in the folder /opt/kaspersky/kuma/core/certificates/. When using TLS, it is impossible to specify an IP address as a URL.
Delimiter	In the drop-down list, you can select the character to mark the boundary between events. By default, `\n` is used.
Buffer flush interval	Time (in seconds) between sending batches of data to the destination. The default value is `1 second`.
Workers	This field is used to set the number of services processing the queue. By default, this value is equal to the number of vCPUs of the KUMA Core server.
Debug	A drop-down list in which you can specify whether resource logging must be enabled. The default value is Disabled.
Disk buffer disabled	Drop-down list that lets you enable or disable the disk buffer. By default, the disk buffer is enabled. The disk buffer is used if the collector cannot send normalized events to the destination. The amount of allocated disk space is limited by the value of the Disk buffer size limit setting. If the disk space allocated for the disk buffer is exhausted, events are rotated as follows: new events replace the oldest events written to the buffer.
Filter	In this section, you can specify the criteria for identifying events that must be processed by the resource. You can select an existing filter from the drop-down list or create a new filter. Creating a filter in resources In the Filter drop-down list, select Create new. If you want to keep the filter as a separate resource, select the Save filter check box. In this case, you will be able to use the created filter in various services. This check box is cleared by default. If you selected the Save filter check box, enter a name for the created filter resource in the Name field. The name must contain 1 to 128 Unicode characters. In the Conditions settings block, specify the conditions that the events must meet: Click the Add condition button. In the Left operand and Right operand drop-down lists, specify the search parameters. Depending on the data source selected in the Right operand field, you may see fields of additional parameters that you need to use to define the value that will be passed to the filter. For example, when choosing active list you will need to specify the name of the active list, the entry key, and the entry key field. In the operator drop-down list, select the relevant operator. Filter operators =—the left operand equals the right operand. <—the left operand is less than the right operand. <=—the left operand is less than or equal to the right operand. >—the left operand is greater than the right operand. >=—the left operand is greater than or equal to the right operand. inSubnet—the left operand (IP address) is in the subnet of the right operand (subnet). contains—the left operand contains values of the right operand. startsWith—the left operand starts with one of the values of the right operand. endsWith—the left operand ends with one of the values of the right operand. match—the left operand matches the regular expression of the right operand. The RE2 regular expressions are used. hasBit—checks whether the left operand (string or number) contains bits whose positions are listed in the right operand (in a constant or in a list). The value to be checked is converted to binary and processed right to left. Chars are checked whose index is specified as a constant or a list. If the value being checked is a string, then an attempt is made to convert it to integer and process it in the way described above. If the string cannot be converted to a number, the filter returns False. hasVulnerability—checks whether the left operand contains an asset with the vulnerability and vulnerability severity specified in the right operand. If you do not specify the ID and severity of the vulnerability, the filter is triggered if the asset in the event being checked has any vulnerability. inActiveList—this operator has only one operand. Its values are selected in the Key fields field and are compared with the entries in the active list selected from the Active List drop-down list. inContextTable checks whether or not an entry exists in the context table. This operator has only one operand. Its values are selected in the Key fields field and are compared with the values of entries in the context table selected from the drop-down list of context tables. inDictionary—checks whether the specified dictionary contains an entry defined by the key composed with the concatenated values of the selected event fields. inCategory—the asset in the left operand is assigned at least one of the asset categories of the right operand. inActiveDirectoryGroup—the Active Directory account in the left operand belongs to one of the Active Directory groups in the right operand. TIDetect—this operator is used to find events using CyberTrace Threat Intelligence (TI) data. This operator can be used only on events that have completed enrichment with data from CyberTrace Threat Intelligence. In other words, it can only be used in collectors at the destination selection stage and in correlators. If necessary, select the do not match case check box. When this check box is selected, the operator ignores the case of the values. The selection of this check box does not apply to the InSubnet, InActiveList, InCategory or InActiveDirectoryGroup operators. This check box is cleared by default. If you want to add a negative condition, select If not from the If drop-down list. You can add multiple conditions or a group of conditions. If you have added multiple conditions or groups of conditions, choose a search condition (and, or, not) by clicking the AND button. If you want to add existing filters that are selected from the Select filter drop-down list, click the Add filter button. You can view the nested filter settings by clicking the button.
