视频会议系统作为多媒体通信系统之一,它的应用也越来越广泛,日趋成为各级政府部门、部队、石化、通讯和各种企业用户广泛应用的一种现代化办公手段。伴随着视频会议系统的广泛需求,其安全问题也随之而来。计算机网络具有联结形式多样性、终端分布不均匀性和网络的开放性、互联性等特征,致使网络轻易受黑客、恶意软件和其它不轨行为的攻击,威胁网络信息的安全。视频会议安全问题之所以重要,是因为如果视频会议系统在安全方面出现问题,有黑客或者是非授权用户非法加入到会议中,则意味着恶意攻击者可以轻易取得管理者的权限、窃取管理者的口令、控制会议、监听会议内容。视频会议系统的安全主要有以下几个方面:1.要能保证会议的唯一性,会议除了合法的与会者外,其他人是应该无法看到和了解的。2.要保证会议的真实性,保证会议的内容不被篡改。3.要确保非法的用户不能加入到会议里面。4.保证会议系统软硬件不会受到非法攻击。
As one of the multimedia communication systems, video conferencing system is also becoming more and more widely used. It has become a modern office widely used by government departments, military units, petrochemicals, telecommunications and various enterprise users at all levels. With the wide range of video conferencing systems, its security problems also follow. Computer networks are characterized by diversity in connection form, inhomogeneous terminal distribution and openness and interconnectivity of the network, which makes the network vulnerable to attack by hackers, malware and other misbehavior and threatens the security of network information. The reason why video conference security is important is that if a video conference system has a security problem and hackers or unauthorized users illegally join the conference, it means that a malicious attacker can easily obtain the rights of a manager and steal administrator’s Password, control conference, monitoring conference content. Video conferencing system security mainly in the following areas: 1. To be able to ensure the uniqueness of the meeting, the meeting in addition to legitimate participants, other people should not be able to see and understand. 2. To ensure the authenticity of the meeting, to ensure that the contents of the meeting have not been tampered with. 3. To ensure that illegal users can not join the meeting inside. 4. To ensure that conferencing hardware and software will not be unlawful attacks.
