Why are wireless LAN networks more vulnerable than wired Ethernet networks?

Wireless networks use the CSMA/CA access method, which is less secure than CSMA/CD.**Edit** The above information is not relevent to how secure a network is. It is however relevant to certain topologies in the infastructure of a network**The correct answer is… Wireless networks transmit data over the open space.The above answer is correct.However, if properly secured a wireless network is much much stronger than one might think.I am a no0b here so if I did anythingincorrect in revising or adding to this post I apologize and encourage an Admin to message me and set me straight.
