ARP poisoning consists of an attacker sending a gratuitous ARP packet (an unsolicited ARP reply) to the target hosts, so that the target client and server both think that the attacker is the host at the other end of the conversation. Just a quick recap - Layer 2 MITM attacks are often based on ARP poisoning, and the mitigation against this is what we’ll be discussing today. We’ll be discussing mitigations that can be applied in most corporate settings (Private VLANs aren’t covered). Today's entry discusses network protections that provide mitigation for all services against such attacks (not just a specific protocol or vulnerability). We've also recently covered recent research in SSL Man in the Middle vulnerabilities and this month's issues concerning MITM attacks against TLS renegotiation. ![]() The article and video illustrate the just how easy it is to mount a man in the middle attack using ARP cache poisoning. Last month ( Day 9 of Cyber Security Awareness Month) we discussed a Man in the Middle (MITM) attack against RDP (Microsoft’s Remote Desktop Protocol), along with Man in the Middle protections for RDP services. ![]()
