river's lake, overlook global, become instant communication market empire. By April 30, 2003, QQ registered users has been more than 1.7 million, online user is supreme 33.9 million, everyday independent online number more than 16 million.
Instant communication can say is the E-mail, WWW after, the Internet of the most lethal applications. Aeryn consultation, a survey of 2003 China instant communication software the highest online number has reached the end of 2004 5.5 million people, hopefully exceeding 7.4 million, 2006 will breakthrough 12 million people.
Instant communication from ICQ. Four youths in Israel cadastral July 1996 established Mirabilis company, and in in November launched the world the first instant communication software ICQ (currently ICQ has to AOL underneath all, meaning \Seek You\
Compared with the traditional telephone, E-mail and other communications way, instant communication not only save costs and higher efficiency. For example enterprise of instant communication systems can always check departments online personnel, communication branches, real-time transmission documents, video conference, remote indiscriminately SMS, etc. Therefore, instant communication is likely to become the security software, ERP software after another enterprise an essential tool, the potential market should not be ignored.
Similarly, in the consumption field, more individual users in steering instant communication applications, some experts think that, in a sense, business instant communication software enterprise is developing into a virtual telecommunications operator. Therefore, instant communication has become the existing telecommunications operators must be involved in the field.
Due to the rise of instant communication software, can real-time communication \is rapidly by voice overall expansion to images and text, data, etc, but \mobile phone and fixed phone etc multiple platform for communications is instant communication future value. A the personage inside course of study thinks, instant communication has already crossed over the original narrowly, \concept, positive more generalized the direction of development, the future of the instant communication software can at any time anywhere and anybody any way of communication, is not only a

voice, including images, information, data and so on, not only on the computer, still can be in mobile, fixed telephone calls and such any terminal.
But, should see that with other Internet application is same, instant communication is originally computer player pets, once rose to business level, its development are faced with the problem will become increasingly obvious, including safety and interworking is the current development of the soft rib of instant communication.
For service providers for different view interworking's position is not consistent. Stronger service most is not willing to realize and other service provider of software compatible, and relative strength of weak service provider, is hoping the real-time communication software compatibility, namely the inter-communication to expand their instant communication software product user groups. In fact, instant communication between software to realize the inter-communication will mainly involves technology and interests two aspects.
Technically, instant communication software between the inter-communication technical operation difficulty is not high, software, realize between interoperate interworking can be done completely. Last September, American Reuters, AOL just signed a cooperative agreement in order to realize the two companies of the instant communication service software the each other between open. So, Reuters instant communication software users will be able to \and write to each other with them.
At present the inter-communication difficult, there is the interworking between enterprises interests distribution. Because most instant communication software users, hope to search through instant communication software realization network communication net friend, would certainly first choose to use already have considerable users of instant communication software.
As for security, whether individual users, or enterprise users, are facing a new threat. For individual users, through instant communication software spread of viruses like hidden bombs, once the outbreak, light is material loss, heavy then computers, have more very person, can cause instant communication between users of misunderstanding.

But for enterprise-level users, an important problem is most instant communication systems is open, which means that the user just know another user instant communication address, he can be directly to send information, which for employees to the external leaks enterprise of commercial secrets of very convenient. And the main characteristics of instant communication is between two end can be directly communicate by any third party, without server transshipment. This makes Internet supervision of instant communication of the user data exchange can monitor the difficulty increases, this lets managers of enterprises greatly headaches. IDC company data show that the global more than 2000 million business people are using instant communication tools, and this number will be in 2005 before gone up 300 million people. The widespread use of instant communication and its lack of safety function characteristics of itself, in order to add encryption, filing and log function products created great demand.
However, as long as have a large user groups, and can have realistic commercial interests, the above two problem will be solved. Recently, AOL, Microsoft and yahoo are mutual cooperation make their instant messaging service realize enterprise environment within the interchange, this also is the industry leader in order to make three different system of computer users to communicate the first major cooperation and breakthrough. Three giant will announce to break their network between \the business world gain wider application of the partnership. In order to use this new system, the enterprises must first obtain Microsoft network software license, the software will act as connection AOL, yahoo and MSN Microsoft, the respective operation system network center.
In terms of security, enterprise application requests obviously higher. Instant communication software in order to adapt to the needs of users, and constantly improve the system of communication ability, namely through the firewall capacity, which could bring negative effect for safety. It requires enterprises to comprehensive consideration of the firewall, anti-virus, intrusion detection, safety evaluation, VPN, many products, according to the specific application of network topology and the specific demand, formulate overall solutions and security strategy. Expert proposal, the enterprise may establish the enterprise internal enclosed real-time information system. So-called closed-end real-time information system in the enterprise is established within their instant messaging servers, in each stage the

personal computer installed on specific real-time information program that can is enterprise self development, also can be the universal, such as BQQ, MSN, etc. Real-time information system fully operational in enterprise Intranet environment does not have any contact with the outside world. Its advantage is can provide enterprises with more secure and reliable audio documents and information transmission services, and network management personnel but also on the enterprise internal real-time information for more effective management. In addition, in the enterprise set up inside real-time information gateway is an efficient way, every employee can use real-time information procedures convenient, quick, but im must pass through the company's internal real-time information gateways, through real-time information gateway for information filtering method and management, any and all information must leave instant communication recording (log files), when necessary information management personnel may, according to the records trace backwards and forwards.
Microsoft security program manager Stephen will present instant messaging threat in the mid 1990s compared to the email virus. He thinks, to avoid to make instant messaging threat to like E-mail threats that flood degree, the influence of education to clients than to instant messaging take technical security measures.
Find most of the instant communication threats are not new threats, similar threats in E-mail had appeared, just changed a kind of new media.
Antivirus designed technology expert Simon says, to attack instant messaging software, hackers without using a new method, now of instant messaging software still to Trojan opened a door.
Because im service software agreement very open, easy to use, hacker thus can easily use them to attack.
AOL said it is developing new security technology, but it also pointed out that the user aware of the dangers facing to alleviate the problem of influence has greater influence. AOL's spokesman Andrew said, in some cases, can take technical measures to protect the user, such as filtering malicious links.
But think the best way is to users instill good behavior habits, even links from friends seem to be friends again, also want to verify it.

Currently, all found of instant messaging threats are in instant messaging software above the Trojan horse running code, rather than using software defect of worms spread, but some experts believe that such a worm virus is just a question of time. History has proved that all software defect, there is always a hackers using these defects.
