    • A system and method is provided that enables older legacy guest operating systems like Windows NT 4.0 and Windows95® to take advantage of newly developed NDIS Intermediate (IM) drivers that support firewalls, quality of service, IP security, intrusion detection, and other functionality for monitoring/filtering incoming and outgoing network traffic in contemporary host operating systems such as Windows XP operating in a virtual machine (VM) environment. The invention thus makes such older legacy operating systems less susceptible to Internet viruses, and worms, network denial of service (DOS) attacks, and the like. For each Virtual Network Interface Card (VNIC) in a guest VM, a corresponding VNIC is created on the host OS, and a point to point connection is established between the guest and host VNICs. The NDIS IM drivers bind themselves on top of the host VNIC and effectively place themselves as a filter on the point to point connection.
    • 提供了一种系统和方法,可以使较旧的旧版客户机操作系统(如Windows NT 4.0和Windows95®)利用新开发的支持防火墙,服务质量,IP安全性,入侵检测和其他功能的NDIS中级(IM)驱动程序 监视/过滤当前主机操作系统中的进出网络流量,例如在虚拟机(VM)环境中运行的Windows XP。 因此,本发明使得这种较旧的旧式操作系统不易受到Internet病毒,蠕虫,网络拒绝服务(DOS)攻击等的影响。 对于来宾虚拟机中的每个虚拟网络接口卡(VNIC),在主机OS上创建相应的VNIC,并且在客户端和主机VNIC之间建立点对点连接。 NDIS IM驱动程序将自身绑定在主机VNIC之上,并将其自身作为点对点连接的过滤器。
