网络安全技术发展至今仍限于被动应用的境地,在防范黑客、病毒等网络威胁方面,传统的网络安全技术只能由单一设备完成。但是,当网络中出现受病毒感染或黑客入侵的傀儡电脑时,这样的设备很难有效阻挡危害的大规模扩散。针对此种情况,D-Link推出区域联防机制,并将其应用在DFL-210 The development of network security technology is still limited to the passive application. To prevent the network threats such as hacking and viruses, the traditional network security technology can only be accomplished by a single device. However, it is difficult for such devices to effectively stop the massive spread of hazards when there are puppets in the network that are infected by viruses or hackers. In this case, D-Link introduced a regional defense mechanism and applied it to the DFL-210
