Strong and Weak Host Models | |
|
||
| Time: 04:31 EST/09:31 GMT | News Source: Microsoft | Posted By: Kenneth van Surksum | ||

An increasingly common configuration for network hosts is to be multihomed with multiple network interfaces. A multihomed host provides enhanced connectivity because it can be simultaneously connected to multiple networks, such as an intranet or the Internet. Because they can be connected to both an intranet and the Internet, however, services running on multihomed hosts can be vulnerable to attack. In order to help prevent attack, and to get an idea of how IP traffic is processed for a multihomed host, I'm going to take a look at the weak and strong host models of multihomed hosts and then describe how these models are supported in Windows.receives packets and impacts the vulnerability of the services running on the host. Although RFC 1122 defines these models for IPv4, they also apply to IPv6. An example of a multihomed host for IPv6 is a computer using both IPv4 and IPv6 that has a network adapter that is connected to an intranet and an IPv6 tunneling interface. | ||
