Warning

You cannot delete security group created by default in the network.

To delete a security group:

Management console

API

In the management console, go to the folder where you need to delete the security group.
In the list of services, select Virtual Private Cloud.
In the left-hand panel, select Security groups.
Click in the line of the group to delete.
In the menu that opens, click Delete.
In the window that opens, click Delete.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

See the description of the CLI command for deleting security groups:
```
yc vpc security-group delete --help
```

Get a list of all security groups in the default folder:

yc vpc security-group list

Select the ID or NAME of the network you need.

yc vpc security-group delete test-sg-cli

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

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

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

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

To delete a security group created with Terraform:

Open the Terraform configuration file and delete the fragment with the security group description.

Example security group description in a Terraform configuration

...
resource "yandex_vpc_security_group" "test-sg" {
  name        = "Test security group"
  description = "Description for security group"
  network_id  = "${yandex_vpc_network.lab-net.id}"

  ingress {
    protocol       = "TCP"
    description    = "Rule description 1"
    v4_cidr_blocks = ["10.0.1.0/24", "10.0.2.0/24"]
    port           = 8080
  }

  egress {
    protocol       = "ANY"
    description    = "Rule description 2"
    v4_cidr_blocks = ["10.0.1.0/24", "10.0.2.0/24"]
    from_port      = 8090
    to_port        = 8099
  }
}
...

In the command line, go to the directory with the Terraform configuration file.
Check the configuration using this command:
```
terraform validate
```
If the configuration is correct, you will get this message:
```
Success! The configuration is valid.
```
Run this command:
```
terraform plan
```
The terminal will display a list of resources with parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.
Apply the configuration changes:
```
terraform apply
```
Confirm the changes: type yes into the terminal and press Enter.

You can check the update using the management console or this CLI command:
```
yc vpc security-group list
```

Use the delete REST API method for the SecurityGroup resource or the SecurityGroupService/Delete gRPC API call, and provide the ID of the security group you want to to delete in the securityGroupId request parameter.

To get the security group ID, use the list REST API method for the SecurityGroup resource or the SecurityGroup/List gRPC API call and provide the folder ID in the folderId request parameter.

To learn how to find out the folder ID, see Getting the folder ID.
