In the previous article (man-in-the-middle attack ARP poisoning), we discussed dangerous hacker attacks and practical ARP poisoning principles. In this article, I will first discuss how to detect and prevent ARP poisoning (or ARP spoofing) attacks, and then I will review other man-in-the-middle attacks-DNS spoofing.ARP cache attacks are very dangerous. It is important to create security awareness and analyze effective tools and policies among users. I
