Door knocks are when an adversary comes knocking where you live to intimidate you or get information. Door knocks aim to intimidate or create paranoia, to see who is willing to talk and possibly be recruited as an informant, and to gather information from the people who do talk.
By logging who you call or visit immediately after they come knocking, the adversary can achieve network mapping.
In many countries, it is easier for the State to carry out door knocks than house raids because door knocks do not require a warrant or legal authorization.
