Network monitoring technique is an important and sensitive technique in the field of network safety. Hackers usually make use of TCP/IP protocol＇s flows to spoof their target. With the combination of network monitoring , hacker can intercept and tamper his target＇s communication data, which is a significant threat to today＇s network security.This paper gives an analysis on the network monitoring theory in switeh Ethernet and puts forward several countermeasures.
