The ARP attack is usual in LAN. I know ESS can detect the ARP attack as there is a option in the advance setting of Firewall. My question is, can ESS really defend against ARP attack and prevent the network communication from been break off,or ESS only "detect" ARP attack? I remember someone ask this question before,but no clear answer is obtained. Is there any guys from ESET can give us a indubitable answer? Thanks in advance!
