CreateSecurityGroup
The CreateSecurityGroup operation creates a
new security group.
Every instance is launched in a security group. If none is specified as part of the launch request then instances are launched in the default security group. Instances within the same security group have unrestricted network access to one another. Instances will reject network access attempts from other instances in a different security group. As the owner of instances you may grant or revoke specific permissions using the AuthorizeSecurityGroupIngress and RevokeSecurityGroupIngress operations.
