kdai(Kernel Dynamic ARP Inspection) is a linux kernel module to defend against arp cache poisoning

This is a comprehensive network security lab, including dhcp snooping, port security and dynamic arp inspection | GNS3

The Holistic Cyber Defence Network Model project designs a secure enterprise network with advanced topology, key protocols, access control, threat mitigation, and monitoring. It offers configuration guidelines and a scalable, tested cybersecurity solution.

Layer 2 attack & defense lab in PNetLab: launch ARP poisoning/MITM, DHCP starvation + rogue DHCP, MAC flooding, and a SYN flood DoS from Kali, then stop each with the matching control (DAI, DHCP snooping, port security, ACL/SYN-flood mitigation) — with before/after proof.
