Is DHCP snooping required for this skill?

DHCP snooping is specifically required if you intend to implement the Dynamic ARP Inspection (DAI) portions of the workflow on your network switches.

Does this require specific hardware?

Hardware-level protection like Dynamic ARP Inspection (DAI) requires managed switches from vendors such as Cisco, Aruba, or Juniper that support DHCP snooping.

What is ARP poisoning?

ARP poisoning is a technique where an attacker sends falsified ARP messages to associate their MAC address with a legitimate IP, enabling them to intercept or modify network traffic.

Can I use this for real-time network monitoring?

Yes, the skill includes a custom Python monitoring script that uses Scapy or tcpdump to provide live alerts on network anomalies and potential spoofing attempts.

How does this Claude Code skill help with detection?

The skill provides automated scripts and configurations for tools like ARPWatch and Wireshark to flag anomalies such as duplicate IP addresses or rapid MAC mapping changes.

セキュリティとテスト

Detects and prevents ARP spoofing attacks using automated monitoring tools and network security configurations to protect against man-in-the-middle interceptions.

This skill provides comprehensive guidance for identifying and mitigating ARP poisoning (ARP spoofing) within Layer 2 network environments. It enables security professionals to deploy multi-layered detection strategies including real-time monitoring with ARPWatch, hardware-level protection via Dynamic ARP Inspection (DAI), and forensic analysis using specialized Wireshark filters. The skill includes a custom Python-based monitoring script to alert on critical anomalies like MAC flip-flopping, gateway impersonation, and ARP floods, making it an essential resource for SOC analysts and network security engineers during incident response and threat hunting operations.
