Understanding Security Groups and Network Access Control Lists (NACLs) in AWS

2024-08-26T09:31:42+00:00

Security within cloud environments is a critical consideration, and AWS offers robust tools to ensure that your cloud infrastructure remains secure. Two critical components in AWS for managing security are Security Groups and Network Access Control Lists (NACLs). These tools act as virtual firewalls, controlling the traffic that enters and exits your Virtual Private Cloud (VPC). While they serve similar purposes, they operate differently and are used in distinct scenarios to provide layered security. Security Groups: Instance-Level Security Security Groups in AWS are designed to control inbound and outbound traffic at the instance level. They are stateful, meaning that if [...]

Don’t Learn AWS Until You Know These Things

2023-05-24T11:39:31+00:00

Learning AWS is like trying to drink from a firehose. At least, that's how I remember it felt when I jumped into AWS years ago as a non-IT guy. I often bounced around between different articles and Youtube videos, struggling to make sense of all the concepts. One moment, I'd be focusing on an EC2 tutorial but then realize I needed to understand VPCs first, so I'd click over to a video about networking. Each time I tried to grasp a new concept, it would lead to another until I found myself lost in a maze of information. It was [...]
