Принцип работы: входящий/исходящий трафик и на основе заданных правил фильтруется контент. В результате информационные пакеты либо пропускаются, либо блокируются.
Брандмауэры бывают двух видов: программные и программно-аппаратные. В свою очередь программно-аппаратный вариант имеет две разновидности — в виде отдельного модуля в коммутаторе или маршрутизаторе и в виде специализированного устройства.
