Glossary of Terms
DMZ (Demilitarized Zone) –
From the military term for an area between two opponents where fighting is prevented. DMZ Ethernets connect networks and
computers controlled by different bodies. They may be external or internal. External DMZ Ethernets link regional networks with
routers.
Firewall –
A device that protects and controls the connection of one network to another, for traffic both entering and leaving. Firewalls are used
by companies that want to protect any network-connected server from damage (intentional or otherwise) by those who log in to it.
This could be a dedicated computer equipped with security measures or it could be a software-based protection.
NAT (Network Address Translation) –
By the network address translation skill, we can transfer the internal network private address of DFL-900 to the public address for
the Internet usage. By this method, we can use a large amount of private addresses in the enterprise.
