Deleting a WAF profile

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 delete a Yandex Smart Web Security WAF profile created with Terraform:

1. Open the Terraform configuration file and delete the section describing the WAF profile.

   Example of a WAF profile description in the Terraform configuration

    # In the basic set, rules of this paranoia level and below will be enabled
    locals {
      waf_paranoia_level = 1
    }
   
    # OWASP Core Rule Set data source
    data "yandex_sws_waf_rule_set_descriptor" "owasp4" {
      name    = "OWASP Core Ruleset"
      version = "4.0.0"
    }
   
    # WAF profile
    resource "yandex_sws_waf_profile" "default" {
      name = "<WAF_profile_name>"
   
      # Basic rule set
      core_rule_set {
        inbound_anomaly_score = 2
        paranoia_level        = local.waf_paranoia_level
        rule_set {
          name    = "OWASP Core Ruleset"
          version = "4.0.0"
        }
      }
   
      # Enabling rules from the basic set if their paranoia level is not higher than the value defined in the waf_paranoia_level variable
      dynamic "rule" {
        for_each = [
          for rule in data.yandex_sws_waf_rule_set_descriptor.owasp4.rules : rule
          if rule.paranoia_level <= local.waf_paranoia_level
        ]
        content {
          rule_id     = rule.value.id
          is_enabled  = true
          is_blocking = false
        }
      }
   
      analyze_request_body {
        is_enabled        = true
        size_limit        = 8
        size_limit_action = "IGNORE"
      }
    }
   

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 deletion of the resources in the management console.

Use the delete REST API method for the WafProfile resource or the WafProfile/Delete gRPC API call.
