VPC Security-Related

    How Do I Ensure the Security of CVMs in VPC Instances?

    The VPC itself is a logically isolated network environment, and traffic can be controlled by configuring security groups and network ACLs:

    • Security group: provides network traffic control for CVMs at the instance level. Traffic that is disallowed to flow in or out of the instance is automatically rejected.
    • Network ACL: provides subnet-level network traffic control.
