hostReputation resource type

Namespace: microsoft.graph.security

[!INCLUDE threatintelligence-api-disclaimer]

Represents the reputation of a host based on a series of rules. This score helps users quickly understand any detected ties to malicious or suspicious infrastructure when validating the reputation of a known or unknown entity. The platform provides quick information about the activity of these entities (such as first and last seen timestamps or autonomous system details) and a list of rules that affect the reputation score when applicable.

Reputation data is important to understanding the trustworthiness of an attack surface and is also useful when assessing unknown hostnames or IP addresses that appear in investigations. These scores uncover any prior malicious or suspicious activity that affected the entity, or other known indicators of compromise to consider.
