ADSL - The faster way to the net.
As published in Industrial Focus Magazine.
The popularity of the Internet has undoubtedly taken the world
by storm; the only drawback has always been cost and speed. Only
the larger companies could afford leased lines for permanent and
hi-speed Internet connection as these start from around £3,500 for
a 64k line. For this reason leased lines did not offer a sensible
solution for the smaller company, leaving you with the choice of
either ISDN or 56K analogue dial-up connections. This only provided
you with slow, and depending on time spent online, expensive connection
costs and frustrated users.
With the introduction of ADSL enabled exchanges around the country
this has all changed. If someone said to you 12 months ago you can
have permanent, hi-speed Internet connection for a low fixed monthly
cost, starting from under £100.00 per month, you would not have
believed them, but now you can.
So what are the benefits of ADSL for your company?
|
|
Fixed low monthly cost |
|
|
Up to 10 times quicker than your standard 56k
connection |
|
|
24:7, "always on" connection |
|
|
E-commerce enabled web-site |
|
|
Wide Area Network (WAN) - the ability to connect
satellite offices into one network |
|
|
Virtual Private Network (VPN) - the ability to
give authorised access to mobile users. |
All this is possible with ADSL and some additional hardware and
configuration.
With all this good news you are understandably waiting for the
bad news, well technically there is no bad news but we can offer
a few words of warning. You will have to address certain security
issues when installing ADSL and configuring the network for Internet
access. Lets use an analogy to highlight the seriousness of this
potential problem. Would you leave your house with the door wide
open and give people the address as you walk along the street? Whilst
doing so, explaining that the door is open and there is no security
in the house to prevent unauthorised access.
Of course not, that would be foolish, but so is installing ADSL
without the added protection of a firewall. With ADSL you are given
a static IP, a permanent address on the Internet. Without a firewall
you are effectively leaving the door wide open and anyone can find
your home. So now we all understand the seriousness of the "potential"
problem, we can confront it. When considering security you should
always presume the worst and prepare for it. A correctly installed
and configured firewall will give you the ability to ensure the
safety of your company information whilst connecting satellite offices
and mobile users.
So lets briefly look at a firewall and its capabilities, a firewall
forms part of a layer of defence on your network. It may work alone
or with other firewalls on your system forming a barrier of inspection
points which analyse the data packets that make up your network
traffic. This traffic is either rejected or allowed to pass through
to the internal network, or commonly referred to as the Intranet.
Only authorised traffic will have the ability to pass safely through
and carry on its journey.
So who or what exactly are we trying to keep out? Unfortunately
there are many reasons that you may have an attack, some of the
more common reasons are.
|
|
Industrial espionage - more common than you would
believe |
|
|
Theft of information |
|
|
Joy riders, hackers and vandals |
These types of intrusion may be to gain access to your valuable
data, financial records, customer lists or marketing strategies.
The more damaging of unauthorised access is by the hackers that
only wish to cause damage and bring down your system.
RW Communications understand that their responsibility does not
end at installing ADSL, but ensure the safety of the network and
push the current technology to the limits. With forward thinking
and the right motivation you can have the same advantages as your
larger competitors but at a fraction of the cost, whilst ensuring
the safety of your network.
