```

```
Output:

                            "GroupId": "sg-903004f8"
                        }

                {
                    "PrefixListIds": [],
                    "FromPort": 22,
                    "IpRanges": [
                        {
                            "Description": "Access from NY office",
                            "CidrIp": "203.0.113.0/24"
                        }

                    "ToPort": 22,
                    "IpProtocol": "tcp",
                    "UserIdGroupPairs": []
                    }
            ],
            "GroupName": "MySecurityGroup",
            "VpcId": "vpc-1a2b3c4d",
            "OwnerId": "123456789012",
            "GroupId": "sg-903004f8",
        }
    ]
}
```
**Contoh 2: Untuk menjelaskan grup keamanan yang memiliki aturan khusus**  
`describe-security-groups`Contoh berikut menggunakan filter untuk lingkup hasil untuk kelompok keamanan yang memiliki aturan yang memungkinkan lalu lintas SSH (port 22) dan aturan yang memungkinkan lalu lintas dari semua alamat (`0.0.0.0/0`). Contoh tersebut menggunakan parameter `--query` untuk hanya menampilkan nama grup keamanan. Grup keamanan harus cocok dengan semua filter yang akan dikembalikan dalam hasil; namun, satu aturan tidak harus cocok dengan semua filter. Misalnya, output mengembalikan grup keamanan dengan aturan yang memungkinkan lalu lintas SSH dari alamat IP tertentu dan aturan lain yang memungkinkan lalu lintas HTTP dari semua alamat.  

```
aws ec2 describe-security-groups \
    --filters Name=ip-permission.from-port,Values=22 Name=ip-permission.to-port,Values=22 Name=ip-permission.cidr,Values='0.0.0.0/0' \
    --query "SecurityGroups[*].[GroupName]" \
    --output text
```
Output:  

```
default
my-security-group
web-servers
launch-wizard-1
```
**Contoh 3: Untuk menjelaskan grup keamanan berdasarkan tanda**  
Contoh `describe-security-groups` berikut menggunakan filter guna mencakup hasil untuk grup keamanan yang menyertakan `test` dalam nama grup keamanan dan yang memiliki tanda `Test=To-delete`. Contoh menggunakan `--query` parameter untuk menampilkan hanya nama dan IDs kelompok keamanan.  

```
aws ec2 describe-security-groups \
    --filters Name=group-name,Values=*test* Name=tag:Test,Values=To-delete \
    --query "SecurityGroups[*].{Name:GroupName,ID:GroupId}"
```
Output:  

```
[
    {
        "Name": "testfornewinstance",
        "ID": "sg-33bb22aa"
    },
    {
        "Name": "newgrouptest",
        "ID": "sg-1a2b3c4d"
    }
]
```
