Para crear un grupo de seguridad para EC2 -Classic

En este ejemplo, se crea un grupo de seguridad denominado MySecurityGroup.

Comando:

aws ec2 create-security-group --group-name MySecurityGroup --description "My security group"

Salida:

{
    "GroupId": "sg-903004f8"
}

Para crear un grupo de seguridad para - EC2 VPC

En este ejemplo, se crea un grupo de seguridad con el nombre MySecurityGroup especificadoVPC.

Comando:

aws ec2 create-security-group --group-name MySecurityGroup --description "My security group" --vpc-id vpc-1a2b3c4d

Salida:

{
    "GroupId": "sg-903004f8"
}
