If, then connecting a terminal for sending to certain local port on this port, action carries out the reception of message;
If action is for being saved in local storage medium, then can carry out checking of original message by directly reading or downloading;
If action is that message is delivered on the far-end server, then need on server, move corresponding receiving software, original message is recombinated and extracted.
In addition, detecting and monitor issuing of rule and action, can be to be finished alone by the network equipment, also can be finished by the network equipment and the combination of other equipment.As the network equipment can with the virus detection server combination, exist when sending viral that message propagates when server detects on the network, can preserve the association message of this viroid by informing network equipment, so that analyze viral source and distribution thereof.
Below by a concrete example technical solution of the present invention is done the example explanation.
For example: the P of enterprise that the network equipment R by the T of operator inserts certain network worm virus at present spreads unchecked, in order to prevent that this virus spread is to whole carrier network, according to this viral feature (TCP message destination slogan is 4444), the network maintenance staff of T is provided with ACL (Access-list on equipment R, Access Control List (ACL)), this type of message with device forwards all abandons.
This moment, the P of enterprise currently infected viral terminal in order to find those, so that take certain treatment measures at these terminals.According to this enterprise IP address characteristic distributions (using network segment X.Y.0.0/16), on equipment R, be provided with as follows:
1) rule:
Abandon type: ACL
+ IP message source address belongs to network segment X.Y.0.0/16
+ IP message protocol number=TCP
+ TCP destination slogan=4444
2) action:
Slave unit R port N sends
Under port N, connect a PC then, carry out message by the software on the PC and grasp, can be easy to analyze current those terminals and infect virus.
