To reduce the risk of inadvertent access, you should define the network boundaries of your system. In this course you'll learn how to uniformly secure access to your entire cluster according to the following traffic pattern table:

Traffic Pattern	Allowed Before	Allowed After

ALB -> APP1 on ports 8000 or 8001

Internet -> ALB on any port
Internet -> APP1 on any port
Internet -> APP2 on any port
