Updated at July 29, 2025

You can edit ARL rules only in an ARL profile. Basic rules, as well as Smart Protection and WAF rules, are edited in a security profile.

  1. In the management console, select the folder with the ARL profile.
  2. In the list of services, select Smart Web Security.
  3. In the left-hand panel, select ARL profiles.
  4. Select the profile where you want to edit a rule.
  5. Next to the rule in question, click and select Edit. In the window that opens:

    1. Edit the basic rule settings:

      • Name.
      • Description.
      • Rule priority. The smaller the value, the higher is the rule priority.
      • Dry run (logging without request blocking) settings.

    2. Under Conditions for traffic, specify the traffic the rule will apply to:

      • All traffic: Rule will apply to all traffic.

      • On condition: Rule will apply to the traffic defined in the Conditions field:

        • IP: IP address, IP address range, IP address region, or address list.
        • HTTP header: HTTP header string.
        • Request URI: Request path.
        • Host: Domain receiving the request.
        • HTTP method: Request method.
        • Cookie: Cookie header string.

        You can set multiple conditions by selecting all the condition types you need in the Conditions field.

        You can also set multiple conditions of the same type by clicking and or or in the section with the condition you need.

        To delete a condition, click .

    3. Change the request counting method and grouping properties:

      • No grouping: To count each request individually.

      • Grouping by property: To count request groups sharing one or more common properties.

        • Select a grouping property:

          Automatic grouping Grouping by key
          Request path: Request path. HTTP cookie: Cookie header string.
          HTTP method: Request method. HTTP header: HTTP header string.
          IP address: Source IP address of the request. Query params: String in the request parameters.
          Region: IP address region of the requests.
          Host: Domain receiving the request.

          To group by key, specify the key value.

        • Optionally, enable Case-sensitive to put properties with the same values in different cases into different groups.

      Specify a request limit or request limit per group, as well as a time interval (1 second to 60 minutes) for the limit. All requests above the limit will get blocked.

    4. Click Save rule.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To edit a rule in an ARL profile:

  1. Open the Terraform configuration file and edit the advanced_rate_limiter_rule section in the yandex_sws_advanced_rate_limiter_profile description.

    # ARL profile

resource "yandex_sws_advanced_rate_limiter_profile" "arl-profile" {
  name        = "<profile_name>"
  description = "<profile_description>"


  # Rule 1

  advanced_rate_limiter_rule {
    name        = "<new_rule_name>"
    priority    = <new_rule_priority>
    description = "<new_rule_description>"
    dry_run     = true

    static_quota {
      action = "DENY"
      limit  = <new_rule_limit>
      period = <new_rule_period>
      condition {
        request_uri {
          path {
            exact_match = "/api"
          }
        }
      }
    }
  }

  # Rule 2

  advanced_rate_limiter_rule {
    name        = "<rule_name>"
    priority    = <rule_priority>
    description = "<rule_description>"
    dry_run     = true

    static_quota {
      action = "DENY"
      limit  = <rule_limit>
      period = <rule_period>
      condition {
        source_ip {
          geo_ip_match {
            locations = ["ru", "kz"]
          }
        }
      }
    }
  }
}

    For more information about the yandex_sws_advanced_rate_limiter_profile properties, see this Terraform provider article.

  2. Apply the changes:

    1. In the terminal, go to the directory where you edited the configuration file.

    2. Make sure the configuration file is correct using this command:

      terraform validate

      If the configuration is correct, you will get this message:

      Success! The configuration is valid.

    3. Run this command:

      terraform plan

      You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.

    4. Apply the changes:

      terraform apply

    5. Type yes and press Enter to confirm the changes.

    You can check the resource updates in the management console.

Use the update REST API method for the AdvancedRateLimiterProfile resource or the AdvancedRateLimiterProfile/Update gRPC API call.
