What did the alien and sedition acts represent

The Alien and Sedition Acts were imposed in 1798, the acts of which made it more difficult for immigrants to become citizens in America, as they were seen as potential threats to National Security. Difficulties such as prolonging the years of residency required for citizenship, deportation and imprisonment, and lack of freedom of speech were all part of the acts that intended to enfeeble the Democratic-Republican party, but rather strengthened the party in the upcoming election in 1800 due to antithetical feedback it received. 

The acts represent the importance of National Security by the Federalists, due to the fact that they were imposed by a Federalist controlled Congress.
