Discover the definition of the term Man-In-The-Middle Attack presented by Les Assises de la Cybersécurité.


Computer attack where the attacker secretly seeks to insert himself into the communication flow between two victims in order to observe or alter it. In such a scenario, each party unknowingly communicates only with the attacker, who then takes charge of relaying the messages from one side to the other. This type of attack is very common, especially on public networks (WiFi in train stations, hotels, etc.). It is possible to protect yourself against it by establishing a virtual private network (VPN).

France invented the concept of Man-in-the-Middle at the end of the 19th century with the appearance of Vaudevilles.
