AP Denial of Service

A DoS attack or distributed denial-of-service attack is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out a DoS attack may vary, it generally consists of concerted efforts to prevent an Internet site or service from functioning efficiently.

One common method involves saturating the target's machine with external communications requests, so it cannot respond to legitimate traffic or responds so slowly as to be rendered effectively unavailable. DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consume its resources so it can't provide its intended service.

The DoS screen displays the types of attack, number of times it occurred and the time of last occurrence.

To view an access point's DoS attack configuration:

1. Select the Statistics menu from the Web UI.
2. Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
3. Expand an RF Domain node, and select one of it's connected access points. The access point's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
4. Expand the Firewall menu.
5. Select Denial of Service.
   The Statistics > AP > Firewall > Denial of Service screen displays in the right-hand pane.

   

   
   This screen displays the following:

   Attack Type	Displays the DoS attack type.
   Count	Displays the number of times the access point‘s firewall has detected each listed DoS attack.
   Last Occurrence	Displays when the attack event was last detected by the access point firewall.

6. Select Clear All to revert the statistics counters to zero and begin a new data collection.
7. Select the Refresh button to update the screen's statistics counters to their latest values.
