Request to add an exclusion to a network isolation rule

To add an exclusion to a previously created network isolation rule, you must create a request to add an exclusion. To create the request, the HTTP POST method is used.

Command settings are passed in the body of the request in JSON format.

Command syntax

curl -k --cert <path to TLS certificate file> --key <path to private key file> -X POST "<URL of Central Node server>:<port, 443 by default>/kata/response_api/v1/<external_system_id>/settings?sensor_id=<sensor_id>&settings_type=network_isolation" -H 'Content-Type: application/json' -d '

{
"settings":
{"excludedRules": [
{
"direction": "<outbound, inbound, or both>",
"protocol": <number of the IP protocol>,
"remoteIpv4Address": "<IP address of the host with the Endpoint Agent component whose traffic must not be blocked>",
"localPortRange":
{
"fromPort": <port number>,
"toPort": <port number>
}
}
,
{
"direction": "<outbound, inbound, or both>",
"protocol": <number of the IP protocol>,
"remoteIpv4Address": "<IP address of the host with the Endpoint Agent component whose traffic must not be blocked>",
"remotePortRange":
{
"fromPort": <port number>,
"toPort": <port number>
}
}
,
{
"direction": "<outbound, inbound, or both>",
"protocol": <number of the IP protocol>,
"remoteIpv4Address": "<IP address of the host with the Endpoint Agent component whose traffic must not be blocked>"
}
]
,
"autoTurnoffTimeoutInSec": <network isolation duration>
}
}
'

If the request is processed successfully, the exclusion from the network isolation rule is added.

Parameter

Type

Description

external_system_id

UUID

Unique ID of the external system used for authorization in Kaspersky Anti Targeted Attack Platform.

sensor_id

UUID

Unique ID of the host with the Endpoint Agent component

direction.

array

Direction of network traffic that must not be blocked. Possible values:

  • inbound
  • outbound
  • both

If you do not specify a value for this parameter, the default value is 'both', which means the application transmits traffic in both directions.

protocol

integer

IP protocol number assigned by the Internet Assigned Numbers Authority (IANA).

If you do not specify a value for this parameter, by default, network isolation is applied to all protocols.

remoteIpv4Address

string

IP address of the host with the Endpoint Agent component whose traffic must not be blocked

remotePortRange

string

Destination port.

You can specify a destination port only if you have selected an inbound or outbound direction of network traffic. Port ranges cannot be specified for bidirectional traffic.

localPortRange

string

Port from which the connection is initiated.

You can specify a destination port only if you have selected an inbound or outbound direction of network traffic. Port ranges cannot be specified for bidirectional traffic.

autoTurnoffTimeoutInSec

integer

Period of time during which the network isolation will be active.

Allowed range - 1 to 9,999 hours. Network isolation time period is specified in seconds. For example, if you want to enable network isolation of a host for two hours, you must specify 7,200 seconds.
