Viewing Denial of Service Statistics
Firewall
A denial-of-service attack (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 a concerted effort to prevent an Internet site or service
from functioning efficiently.
One common attack involves saturating the target’s (victim’s) machine with external
communications requests, such that 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 consuming its resources so that it can no longer provide its
intended service.
The Denial of Service screen displays attack type, number of occurrences, and time of last
occurrence.
To view the denial of service statistics:
1. Select the Statistics menu from the Web UI.
2. Select a Wireless Controller node from the left navigation pane.
3. Expand the Firewall menu from the left-hand side of the UI.
4. Select Denial of Service.
