和传统的安全需求相比,WLAN.GPRS.3G 等也需要采用防火墙.VPN、入侵检测、病毒扫描等安全产品。无线和有线在安全需求上没有差别。据预测,到今年年底全球手机上网数量将超过个人电脑。这将产生两个问题:基于无线网络的安全威胁日益突出;我们还没有做好充分准备来迎接这种新威胁的挑战。随着 PDA 操作系统,例如Symbian OS.Palm 和 PocketPC 由单个终端移植到智能电话和无线 PDA 中,这些终端与其他设备的连通能力得到了极大的加强,成为有特色的、灵活的、能够无线下载和运行第三方功能的平台,但同时受攻击的几率也大大增加了。
And traditional security needs, WLAN.GPRS.3G also need to use the firewall.VPN, intrusion detection, virus scanning and other security products. There is no difference in security requirements between wireless and wired. It is predicted that by the end of this year, the number of global handsets will surpass that of personal computers. This creates two problems: security threats based on wireless networks are becoming increasingly prominent; we are not yet fully prepared to meet the challenge of this new threat. As PDA operating systems, such as Symbian OS. Palm and Pocket PC, are ported from a single terminal to smart phones and wireless PDAs, these terminals are greatly enhanced in their ability to communicate with other devices as a feature-rich, flexible, Download and run third-party features platform, but also greatly increased the chances of attack.
