Making facilities 
robust and controlling 
access 
Locating facilities and installations requiring protection 
such that accessing them requires a certain distance to 
be covered and takes a certain time is a key aspect in 
preventing terrorist attacks and sabotage. Barriers and 
obstacles can hinder or prevent access to sensitive areas 
(access zones, access controls, plant security, gates, 
fencing, patrols, bollards, concrete elements, elevations).
Concealed areas can be monitored with electronic 
security systems (video surveillance, motion detectors, 
noise sensors, thermal imaging cameras, night vision 
devices).
The importance of gates to security generally extends 
beyond controlling access. In this context, the question 
as to security for the gates themselves arises. If, for 
example, the main gate is the sole point for receiving 
alarm and fault messages (frequently after the normal 
service hours of the operating area concerned), it must 
not be possible to prevent the relay of these messages to 
support centres by interfering with the communication 
facilities or threatening the security staff at the gate. This

is to be ensured via appropriate protection measures. It is 
also of central importance that the gate / security centre 
be continuously manned.
An understanding of security considerations for the 
operating area is to be instilled in the personnel, who are 
also to be involved in security processes through team 
training, seminars, etc.

In most cases, the measures to secure the site as a whole 
serve to provide basic protection; they provide an initial 
barrier to ward off unauthorised persons. Special individual 
protection is additionally required for all points of danger. 
“Classical” measures to secure facilities and installations play 
a major role here.
