Security Group

Introduction​

By default, network access is turned off to a ECS instance. You can specify rules in a security group that allows access from an IP address range, port, or ECS security group.

You must specify port numbers (for TCP):

  • SSH: 22
  • HTTP: 80
  • HTTPS: 443
  • Ftp: 21, 20000-30000
