Also, if there was a security emergency too serious for the reuglar security force to handle, it would be far more practical to give any available officer and crewman a phaser and have them help fighting the enemy. After all, combat training is presumably part of Starfleet basic.
Emergency Force fields would take care of nearly all security problems on board the ship.
