Security Groups Insights

What is Security Groups?

Security Groups act as a virtual firewall for controlling inbound and outbound traffic to network interfaces (like virtual machines) within a network. They use rules to filter traffic based on protocols, ports, and source/destination IP addresses or CIDR blocks. They are commonly used to restrict access to applications and services, enhance network security, and isolate network segments.
