        Default Security Groups and Security Group Rules

        -
        The system creates a default security group for each account. By default, the default security group rules:
        • Allow all outbound packets: Instances in the default security group can send requests to and receive responses from instances in other security groups.
        • Deny all inbound packets: Requests from instances in other security groups will be denied by the default security group.
        +

        Default Security Group and Its Rules

        +
        If you have not created any security group, the system automatically creates a default security group for you and associates it with the instance (such as an ECS) when you create it. A default security group has the following rules:
        • Inbound rules control incoming traffic to instances in a security group. Only instances in the same security group can communicate with each other, and all inbound requests are denied.
        • Outbound rules allow all outbound traffic and response traffic to the outbound requests.
        Figure 1 Default security group
        -
        • You cannot delete the default security group, but you can modify the rules for the default security group.
        • If two ECSs are in the same security group but in different VPCs, the ECSs cannot communicate with each other. To enable communications between the ECSs, use a VPC peering connection to connect the two VPCs.
        +
        • You cannot delete the default security group, but you can modify existing rules or add rules to the group.
        • The default security group is automatically created to simplify the process of creating an instance for the first time. The default security group denies all external requests. To log in to an instance, add a security group rule by referring to Remotely Logging In to an ECS from a Local Server.

        Table 1 describes the default rules for the default security group.

        Adding Instances to and Removing Them from a Security Group

        Scenarios

        After a security group is created, you can add instances to the security group to protect the instances. You can also remove them from the security group as required.

        Adding an Instance to or Removing an Instance from a Security Group

        +

        Scenarios

        When you create an instance, the system automatically adds the instance to a security group for protection.
        • If one security group cannot meet your requirements, you can add an instance to multiple security groups.
        • An instance must be added to at least one security group. If you want to change the security group for an instance, you can add the instance to a new security group and then remove the instance from the original security group.

        Firewall Overview

        A firewall is an optional layer of security for your subnets. After you associate one or more subnets with a firewall, you can control traffic in and out of the subnets.

        Figure 1 shows how a firewall works.

        Figure 1 Security groups and firewalls

        Similar to security groups, firewalls control access to subnets and add an additional layer of defense to your subnets. Security groups only have the "allow" rules, but firewalls have both "allow" and "deny" rules. You can use firewalls together with security groups to implement comprehensive and fine-grained access control.

        Differences Between Security Groups and Firewalls summarizes the basic differences between security groups and firewalls.

        Firewall Basics

        • Your VPC does not come with a firewall, but you can create a firewall and associate it with a VPC subnet if required. By default, each firewall denies all inbound traffic to and outbound traffic from the associated subnet until you add rules.
        • You can associate a firewall with multiple subnets. However, a subnet can only be associated with one firewall at a time.
        • Each newly created firewall is in the Inactive state until you associate subnets with it.

        Default Firewall Rules

        By default, each firewall has preset rules that allow the following packets:
