# Performing ARP Spoofing Attack Simulation ## When to Use - Testing whether network switches and infrastructure properly implement Dynamic ARP Inspection (DAI) - Demonstrating man-in-the-middle attack risks to stakeholders during authorized security assessments - Validating that network monitoring tools (IDS/IPS, SIEM) detect ARP cache poisoning attempts - Assessing the effectiveness of port security, 802.1X, and VLAN segmentation controls - Training SOC analysts to recognize ARP spoofing indicators in network traffic **Do not use** on production networks without explicit written authorization and a rollback plan, against networks carrying critical or life-safety traffic, or as a denial-of-service attack vector. ## Prerequisites - Written authorization specifying in-scope network segments for ARP spoofing simulation - Kali Linux or similar penetration testing distribution with arpspoof, Ettercap, and Scapy installed - Direct Layer 2 access to the target network segment (same VLAN as target hosts) - IP forwarding knowledge and ability to enable/disable packet forwarding on the attacker machine - Wireshark or tcpdump for capturing traffic to verify interception - Isolated lab environment or approved production test window > **Legal Notice:** This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws. ## Workflow ### Step 1...
