Pharming is a dangerous attack that includes MITM (Man in The Middle), DNS poisoning and others, which is difficult to detect. In recent years, it has become more and more prevalent, affecting a growing number of organizations around the world. By implementing the VERSAFE Anti-Pharming online mechanism, which detects different types of Pharming attacks, it is possible to identify servers that execute MITM attacks, and also to identify the users targeted by these attacks, in real time. The use of these protective components allows preventing connection from a public network in which Pharming attacks are carried out, including ARP poisoning, DNS poisoning and others.
