Join Brian Eiler for an in-depth discussion in this video NACLs and security groups, part of Amazon Web Services: Implementing and Troubleshooting IaaS Products.
- [Instructor] Now that you know how to set up the VPCs…and build the subnets and the CIDR blocks,…we're going to look at some of the security aspects.…First, we're going to look at something called NACLs,…which stands for network access control list.…The next topic will be security groups.…They're both software-defined firewalls, really,…but they have different functions…and they're applied in different areas.…Let's start off with NACLs.…As we said, they're network access control list…and they're going to operate a bit like a firewall.…
They control the traffic flow in…and out of your subnets.…They're not applied to individual instances…like your EC2 instance or load balancers.…These are controlling perimeter access,…so, what can come and go from a subnet.…The rules that are in these network access control list…are processed in numerical order, top, down,…which means the first rule that you put in,…if it matches the traffic that's seen,…we'll go ahead and execute upon that rule…and stop processing.…
This is in stark comparison to some other technologies…
- AWS global infrastructure
- VPC use cases
- EC2 instance types
- EC2 purchasing and troubleshooting
- Creating AMIs
- Using AWS storage solutions such as EBS, EFS, S3, and Glacier
- Versioning and cross-region replication on S3
