Intrusion Prevention Level
You can select the following prevention levels:
 Block: A single sensor can block unwanted communication on any one channel in the 802.11b/g band and any
one channel in the 802.11a band.
 Disrupt: A single sensor can disrupt unwanted communication on any two channels in the 802.11b/g band and
any two channels in the 802.11a band.
 Interrupt: A single sensor can interrupt unwanted communication on any three channels in the 802.11b/g band
and any three channels in the 802.11a band.
 Degrade: A single sensor can degrade the performance of unwanted communication on any four channels in
802.11b/g band and any four channels in the 802.11a band.
Block is the most powerful prevention level, that is, it can severely block almost all popular Internet applications
including ping, SSH, Telnet, FTP, HTTP, and the like. However, at this level, a single sensor can simultaneously
prevent unwanted communication on only one channel in the 802.11b/g band and one channel in the 802.11a band. If
you want the sensor to prevent unwanted communication on multiple channels simultaneously in the 802.11 b/g
and/or the 802.11a band, you must select other prevention levels.
Note: Prevention Type determines the blocking strength to prevent communication from unwanted APs and Clients.
The system can prevent multiple APs and Clients on each channel. Prevention Type is not applicable for Denial of
Service (DoS) attacks or ad hoc networks. You must select a lower blocking level to prevent devices on more channels.
Choosing a lower blocking level means that some packets from the blocked device may go through.
