Instant messaging software (IMS) provides a platform for the communication of information. It convenient for people to communicate, at the meantime enterprises and institutions, companies, families, local area network has security implications. Such as access to user’s personal information and the company’s trade secrets; dissemination of pornography, reactionary remarks; provide attack corridors for Trojans and worms. Therefore, study the detection and blocking techniques of instant messaging software to protect the security of local area network has great application value.

Through analyzing and summing up the network architecture and the communication protocol of IMS, a universal detection technology of IMS has been presented, which is detect communication protocols of IMS. When detecting the instant messaging software, dynamic link library of WinPcap systems in Windows systems should be used.
