Access Control for ECS

IAM Identity Authentication

IAM provides fine-grained permissions management, user identity authentication, and resource access control.

You can use your account to create IAM users, and assign permissions to the IAM users to control their access to specific resources. IAM permissions define which actions on your cloud resources are allowed or denied.

Access Control

• VPC

  Virtual Private Cloud (VPC) allows you to create customized virtual networks in your logically isolated AZ. Such networks are dedicated zones that are logically isolated, providing secure network environments for your ECSs. You can define security groups, virtual private networks (VPNs), IP address segments, and bandwidth for a VPC. This facilitates internal network configuration and management and allows you to change your network in a secure and convenient network manner. You can also customize the ECS access rules within a security group and between security groups to improve ECS security.

• Security Group

  A security group is a collection of access control rules for ECSs that have the same security protection requirements and that are mutually trusted. By adding an ECS to a security group, you apply all the rules defined for this security group to this ECS.

For details about how to configure a VPC and security group, see Step 2: Configure Network.
