Internet security This article provides tips on how to make sure you can be safe on the Internet and how to keep computer viruses, malware, and other unwanted software off your computer. Gas Motorcycle Routers Network Address Translation (NAT) typically has the effect of preventing connections from being established inbound into a computer, whilst permitting connections out. Getting a router in your home improves the security of a home LAN; some people consider that they don't need a firewall if they have a router. However, for a small home network, software NAT can be used on the computer with the internet connection, providing similar behaviour to a router, and similar levels of security but for a lower cost and lower complexity . A firewall blocks all traffic except through authorized ports
on your computer, thus restricting unfettered access. A stateful firewall is a
more secure form of firewall, and system administrators often combine a proxy
firewall with a packet-filtering firewall to create a highly secure system; this
would be overkill for a home system, but is more common in business. Most home
users would use a software firewall, while some high risk servers and computers
might need a
hardware firewall. |
