Description

Policy Rule

 

 

Threshold

Notification

 

 

 

 

Unauthenticated

Attack. Multiple unauthenticated association requests (5 or

5

Trap

association

more) that use spoofed MAC addresses of legitimate clients are

 

 

 

sent to the wireless access point.

 

 

 

Result. The client association table overflows, causing

 

 

 

authentication requests from legitimate clients to be denied.

 

 

 

Solution. The oldest clients that are stuck in the authentication

 

 

 

phase are removed from the table.

 

 

 

 

 

 

Association table

Attack. Multiple clients (5 or more) that use spoofed MAC

5

Trap

overflow

addresses of legitimate clients attempt to connect to the

 

 

 

wireless access point.

 

 

 

Result. The client association table overflows, causing

 

 

 

association requests from legitimate clients to be denied.

 

 

 

Solution. The oldest associations are removed from the table.

 

 

 

 

 

 

Authentication

Attack. Multiple invalid authentication requests (5 or more) that

5

Trap

failure attack

use the spoofed MAC address of a legitimate client are sent to

 

 

 

the wireless access point.

 

 

 

Result. The client is disconnected from the wireless access

 

 

 

point.

 

 

 

Solution. The wireless access point determines if the legitimate

 

 

 

client is already connected before processing an authentication

 

 

 

request.

 

 

 

 

 

 

Deauthentication

Attack. Multiple deauthentication frames (5 or more) that use

5

Trap

broadcast attack

the spoofed MAC address of the wireless access point are sent

 

 

 

to legitimate clients.

 

 

 

Result. Clients are disconnected from the wireless access

 

 

 

point.

 

 

 

Note: The IDS detects this attack, but the IPS does not take action

 

 

 

against this attack.

 

 

 

 

 

 

Disassociation flood

Attack. Multiple disassociation frames (5 or more) that use the

5

Trap

 

spoofed MAC address of the wireless access point are sent to a

 

 

 

legitimate client.

 

 

 

Result. The client is disconnected from the wireless access

 

 

 

point.

 

 

 

Note: The IDS detects this attack, but the IPS does not take action

 

 

 

against this attack.

 

 

 

 

 

 

Malformed 802.11

Detection. Multiple malformed packets (5 or more) are sent to

5

Trap

packets detected

the wireless access point.

 

 

 

Result. Clients behave unexpectedly or crash.

 

 

 

Solution. The wireless access point drops the malformed

 

 

 

packets.
