10. A system, comprising: a database configured to store domain hierarchies; and a hierarchical domain search engine, configured to: analyze the domain hierarchies in the database to determine a reputability score for a domain associated with a domain assessment request; determine whether a first domain level in at least one of the domain hierarchies matches the domain associated with the domain assessment request; use a first reputability value associated with the first domain level for determining the reputability score when the first domain level matches the domain; determine whether a second sub-domain level of the first domain level matches the domain associated with the domain assessment request; and use a second reputability value associated with the second sub-domain level associated with a higher reputability than the first reputability value for determining the reputability score when the second sub-domain level matches the domain associated with the domain assessment request.

The system of claim 10 , wherein the hierarchical domain search engine is configured to adjust the reputability score according to traceability and association information associated with the domain.
