Firewalls and Routers

For your protection, Mintel supplies a firewall/router inside the modem. The

real issue is how to make your computer secure when it is connected. Not

having protection is like leaving your car running with the doors unlocked and

the keys in it which a thief might interpret as "please steal me”. Locking a car,

using a "club" or installing a security system makes stealing a car more

difficult, as is having your computer behind a Firewall or a Router makes it

harder to hack into.

What is a Firewall?

A system designed to prevent unauthorized access to or from a private

network. Firewalls can be implemented in both hardware and software, or a

combination of both. Firewalls are frequently used to prevent unauthorized

Internet users from accessing private networks connected to the Internet,

especially intranets. All messages entering or leaving the intranet pass-through

the firewall, which examines each message and blocks those that do not meet

the specified security criteria.

For connecting two or more computers to the Internet, you should use a

hardware router with firewall features along with your personal firewall

software.

What is a Router?

It is a device that forwards data packets along networks. A router is connected

to at least two networks, commonly two LANs or WANs or a LAN and its

ISP’s network. Routers are located at gateways, the places where two or more

networks connect. Routers use headers and forwarding tables to determine the

best path for forwarding the packets, and they use protocols such as ICMP to

communicate with each other and configure the best route between any two

hosts.

supplied by Mintel.
