One of the main policies was HUAC (House of Un-American Activities Committee) which investigated alleged communists.

Another is the Loyalty Review Board, which investigated government officials accused of being communist spies or moles.

Dennis vs. United States in Supreme Court set the standard to send alleged communists to prison for speaking out against the government.

Then you have the traditional Containment Doctrine and Truman Doctrine.
