Join Brandon Rich for an in-depth discussion in this video Understand AWS security groups, part of Amazon Web Services: Deploying and Provisioning.
- [Narrator] Let's take a look at how Amazon Web Services…handles the important topic of network security,…using AWS Security Groups.…First, a look at a traditional firewall setup.…Imagine this is our data center.…We have a few web servers, maybe a public API host.…We also have some private hosts, things like databases…that we want locked down and secure.…In our simplified data center, we've divided…our space into subnets.…Public on the left, private on the right.…And because we're good system architects,…concerned about security, we have a firewall…around the whole thing.…
The firewall protects the whole data center at the border.…We define rules for what traffic goes in and out.…We let the good guys in, like our web users,…which we allow in on ports 80 and 443.…We lock everything else down, keeping the bad guys out.…We also configure the firewall to let servers talk…out to the world where appropriate,…like when we need to call an external API.…Of course, the firewall doesn't just protect the border,…it can also govern traffic inside the data center.…
