Security Groups vs. Network ACLs: Choosing Your AWS VPC Firewall
Navigate the complexities of AWS VPC security by mastering the differences between Security Groups (SGs) and Network ACLs (NACLs). This expert guide explains the scope, statefulness, and rule evaluation of both controls. Learn why SGs are ideal for fine-grained, stateful instance protection, while NACLs are essential for broad, stateless subnet segmentation and explicit denial policies. Implement a robust, multi-layered firewall strategy for your cloud infrastructure.
