Secure Your Wireless Network
To secure your wireless computers within
your network, you need to proactively protect your data and
keep your systems safe. The first step in securing your
network is to use the standard built-in features found in
your gear. Most networking devices have built-in security
features to keep hackers at bay; but in most cases, it is
not enough security. Thankfully, most broadband routers have
Network Address Translation (NAT) security and Media Access
Control (MAC) address filtering, but make sure these
features are included. Routers with NAT hide internal
network IP addresses (which add a layer of network
security). MAC address filtering features allows you to
enter the MAC addresses you want to grant or deny access to
your network.
Typically, wireless-networking devices
are inclusive of WEP and WPA encryption features. Both of
these forms of encryption are beneficial in protecting your
network. But, keep in mind, the WPA is more secure than the
WEP feature. To use either one of these encryption features,
you need to enter an encryption key to all wireless devices
in your network. Product user manuals explain how to do
this. Even though most home office networks and small
businesses do not use authentication features for their
local computers, most large businesses choose to use it for
their office LANs (i.e. 802.1x or LEAP).
The second step is to get a hardware
firewall for your network. A hardware firewall works the
same way as a software firewall but there are certain other
advantages. Whereas a software firewall must be installed on
each computer in your network, a hardware firewall
centralizes the control of connections between your network
and the Internet. Hardware firewalls are more effective than
software firewalls in that they can make multiple computers
play by the same rules at the same time. In addition,
hardware firewalls use their own processors for port
filtering and encryption tasks, which means that there is
little or no resource drain on the computers in your
network, giving you better overall performance. Some
firewalls allow you to set-up VPN connections from the
Internet to your personal LAN, providing you with a secure
way to access your computers while you're on the road.
Because Cisco's PIX security appliances have multi-vector
attack protection services, they can effectively defend
businesses from many popular forms of attacks, such as:
denial-of-service (D0S) attacks, fragmented attacks, replay
attacks, and malformed packet attacks. The benefits deriving
from PIX firewalls are: improved productivity, lower
operational costs, and increased competitive advantage. If
