A security guard is a person employed by a government or private party to protect the employing party's assets from a variety of hazards by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking for signs of crime or other hazards, taking action to minimize damage, and reporting any incidents to their clients and emergency services, as appropriate.
