About

The Firewalls mind map template provides a technical architecture for network security professionals, covering 29 distinct nodes across essential security layers. This Firewalls cheat sheet serves as a structured reference for configuring cloud and local network environments, specifically detailing how 'Firewall rules are stateful' and the logic behind 'Action on match'. It outlines the critical hierarchy where the 'Lowest priority number is the highest priority', ensuring administrators understand rule precedence. By utilizing this Firewalls template, IT teams can visualize the relationship between 'Network Tags' and 'Compute Engine instances', facilitating a more secure VPC network setup. The content is fact-dense, covering specific protocol restrictions such as the blocking of 'GRE traffic' and the default allowance of 'DHCP, DNS, and NTP' services.

Frequently asked questions

This template includes a comprehensive breakdown of firewall rules, protocols, components, and network tags. It covers specific behaviors like stateful enforcement, priority numbering, and default protocol permissions for TCP, UDP, and ICMP traffic.

Use this template to audit your current security posture by comparing your active rules against the 'Protocols' and 'Components' branches. It helps in mapping out 'Ingress' and 'Egress' traffic flows to ensure no unauthorized ports are open.

Yes, this template is fully editable. You can add custom nodes for specific IP ranges, modify the 'Action on match' logic for your organization, or include specific 'Network Tags' relevant to your cloud infrastructure.

The 'Network Tags' structure is used to define how text attributes are applied to Compute Engine instances. It illustrates how these tags facilitate the routing of firewall rules to specific instances within a VPC network.
