1.1 Perimeter
In IT security, the perimeter is the area over which an entity has physical and logical access control.
a company's office network connected to the Internet can constitute a perimeter, even if this network is deployed on several distinct geographical sites and in several countries.
A perimeter is often made up of several "sub-perimeters", as the level of risk varies according to the different networks making up the company. For example, as illustrated in figure 1, a demilitarized zone, the office network, the accounting department network and the R&D department network make up the company perimeter.
