7. Good physical perimeter security

Effective physical security can create significant delays and in some instances even barriers to an attacker. A stalker who had vowed to kill a Georgia primary school teacher was arrested by police after he repeatedly and unsuccessfully tried to defeat the school’s perimeter security. School district police officers recovered a loaded .32 caliber semi-automatic pistol from the man’s waistband. In addition to preventing some attacks, good physical perimeter security can make it more difficult for a potential attacker to surveil a campus to plan an attack.
