Understanding Firewall Rules

Administrators consider firewall rules for Google Cloud Platform (GCP) as a means of protecting their virtual machines (VMs). They decide which traffic can be allowed to the enter or exit your virtual machine instances based on established requirements. By imposing firewall rules that control who may use your virtual machines (VMs) and the kinds of data that can travel through them, users can prevent malicious attempts and unauthorized access to your applications....

Types of Firewall Rules

Predefined Rules: These are the basic firewall rules for the GCP, supporting common use cases such as allowing HTTP and HTTPS traffic. They are functional and provide your virtual machines (VMs) with some simple protection rules. Custom Rules: Users can make these user-defined firewall rules to satisfy the particular needs that are not addressed by existing regulations. You may generate them based on protocols, ports, IP ranges, and other factors to control traffic flow more precisely. Ingress vs. Egress Rules: Users can design these user-defined firewall rules to meet specific needs not addressed by the rules as they stand. You can build them based on protocols, ports, IP ranges, and other parameters to accurately regulate traffic flow....
