hostPair resource type

  • Artikkeli

Namespace: microsoft.graph.security

Note

The Microsoft Graph API for Microsoft Defender Threat Intelligence requires an active Defender Threat Intelligence Portal license and API add-on license for the tenant.

Represents a pair of parent-child hosts in which the child host is able to be reached via the parent host. For example, if contoso.com redirects to microsoft.com, then contoso.com represents the parent host and microsoft.com the child host.

Host pair relationships shared at an earlier point, or currently share a connection observed from a Microsoft crawl. A parent host leads to the child host perhaps through a simple top-level redirect (HTTP 302), or something more complex like an iframe or script source reference. In other instances, a web crawl may reveal odd behaviors such as host pair relationships between IP addresses and domains/hosts that go against DNS standards.

The linkKind property notes the reason to identify the hosts as a parent-child pair. An example of this may be redirect.

For more information about host pairs, see the Microsoft Defender Threat Intelligence documentation for data sets.
