Abstract
Method for securing communication in a local area network switch (AN) comprising a user interface (UI) and a network interface (NI), comprises the steps of extracting a source address (MACi) from each packet received by said Local area network switch (AN) and storing said address (MACi) together with associated information into a address forwarding table (FT) comprised in said Local area network switch (AN) is characterised in that a distinction is made between source addresses received from the user interface (UI) and the network interface (NI), such that upon detecting that a source address (MACi) contained within a newly received packet at the user interface (UI) was already stored as a source address received at the network interface (NI), said newly received packet will be discarded and its source address contained therein will not be stored within said address forwarding table (FT).
