GCP firewall ingress flow architecture for Malwee organization consolidating 30+ fragmented rules across Ansible automation, vulnerability scanning, monitoring, and PAM access. Traffic flows from external sources (Internet, partners, Google Cloud Console IAP, Cloudflare CDN) through a core ingress rule layer distributing allow-rules to multiple GCP projects including Compute Engine, SAP endpoints, ADFS, and Databricks clusters. The design demonstrates least-privilege segmentation with protocol-specific rules for SSH/RDP/WinRM to Ansible servers, Nessus scanners, Zabbix monitors, and PAM hosts across production and development environments. Security architects can fork this diagram to audit rule consolidation opportunities, validate source IP ranges, and implement the proposed Shared VPC Host consolidation reducing complexity from 30+ rules to 5 function-based rules.
