DOS attacks

DOS type attacks at layer 1 as well as layer 2 are easily executed in a wireless network.  Emitting  a  very  strong  RF  interference  on  the  channel  in  which  the wireless network is operating on will increase the noise on that channel and thus causing interference to  all  wireless  networks that  are  operating  at /  near that channel.

Layer  2  type  DOS  attacks  come  in  the  form  of  packet  injection,  where  the attacker  will  flood  wireless  clients  who  are  already  attached  to  the  wirelessnetworks with disassociate or deauthenticate packets. Example of such a tool is Void11.
