  Networking 101

Cloud computing fundamentally requires a network. To understand the basics of network and infrastructure security, you will need to understand IP (Internet Protocol) networking. If you don't know what means, you may need to review some IP networking.

  1. IPv4 and IPv6 addresses
  2. Public and private address ranges
  3. Subnetting and CIDR
  4. Port numbers
  5. What does a firewall do
  6. What is NAT

A basic introduction to some of these can be found in this video. If you feel unsure about your knowledge level, consider reviewing the video, even though it does not cover all of the topics above. It is less than 10 minutes. Please put additional questions in the discussion session. We are here to help you.
