Deleting a WAF exclusion 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 documentation on the Terraform website or mirror website.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

1. Open the Terraform configuration file and delete the exclusion_rule section with the WAF exclusion rule from the description of the yandex_sws_waf_profile security profile.

   Below is an example of an exclusion rule description in the Terraform configuration

   # WAF profile
   resource "yandex_sws_waf_profile" "default" {
     name = "waf-profile-default"
     core_rule_set {
       inbound_anomaly_score = 2
       paranoia_level        = local.waf_paranoia_level
       rule_set {
         name    = "OWASP Core Ruleset"
         version = "4.0.0"
       }
     }
   
     ...
   
     # Exclusion rule
     exclusion_rule {
       name = "<exclusion_rule_name>"
       exclude_rules {
         exclude_all = <true_or_false>
         rule_ids    = ["rule_1_ID","rule_2_ID"]
       }
     }
   }
   

   For more information about the sws_waf_profile resource parameters in Terraform, see the relevant provider documentation.

2. Apply the changes:

   1. In the terminal, change to the folder where you edited the configuration file.

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

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

You can check the deletion of the resources using the management console.
