Guide engineers through configuring firewalls across host-based (iptables, nftables, UFW), cloud-based (AWS Security Groups, NACLs), and container-based (Kubernetes NetworkPolicies) environments with practical rule examples and safety patterns to prevent lockouts and security misconfigurations.
Apply: sudo nft -f /etc/nftables.conf Enable on boot: sudo systemctl enable nftables
For advanced patterns (sets, maps), see references/nftables-patterns.md
Configura firewall basati su host (iptables, nftables, UFW) e gruppi di sicurezza cloud (AWS, GCP, Azure) con regole pratiche per scenari comuni come server Web, database e host bastion. Da utilizzare quando si espongono servizi, si rafforzano i server o si implementa la segmentazione della rete con strategie di difesa approfondite. Fonte: ancoleman/ai-design-components.
