Inside Network 2

Inside Network

Inside networks are also referred to as the internal or private networks. The inside area is made up of the corporate network(s), including all workstations and, typically, any servers not shared with the outside world. These devices are considered trusted and can be accessed freely by other inside hosts. These trusted devices need to be protected from the outside world and even from attackers that might have compromised the DMZ area(s). The inside area is under one administrative authority and operates under a common security plan.

The inside area is often connected to one of the firewall interfaces, the inside interface. Additional firewalls might be used within the inside area to offer secure separation between two or more subnets. The company security policy might specify a firewall between the accounting/finance departments and the other operating units.
