sorry, i'm not asking wmi event lead to a denial of service attack....my query is..if denial of service happen in some system..then how can i notify (by sending events) to my server..that "dos" is happen in host on this port.... there is any wmi or non-wmi mechanism available...
As cloud255 said you need to get some 3rd party security software...for your server ....or at the very basic check if your server is bombarded with requests, then block the IPs from which the attack is originating... though dos recognizing and response ( action such as notifying admin n shuttin down server temporarily)is in itself a very large area...
It will be diffcult to do it in a restricted time frame and limited resources .. Look for security software...specific to DOS..
"any wmi or non-wmi mechanism available"
As far as i know there is no wmi mechanish available for this...
