Wired or Wireless which will you use? Or will you use both?
How much is your data worth?
is cheap, one has a higher security rating...
Wired? more secure, lower
maintenance and setup, initial cost is high.
Wireless? less secure, higher maintenance and setup, initial cost is lower
Physical Security -
Wired networks have the highest security because for someone to access your
network they have to have physical access to the network; they have to be
present in your premises to get access to the network. Very visible to you
and/or your employees.
Wireless networks work on a Radio Frequency, there for anyone with the knowledge
and some equipment (not really sophisticated spy type stuff either) can tap into
your network's radio frequency. Now connecting to your network is a deferent
problem, but they can see your network with a laptop and a wireless network
02/15/14 - In the USA the Supreme Court has judged that "There is no
expectation of privacy with a radio transmission." i.e.: Your cell phone
like your wireless network is a radio transmitter / receiver set there for all
transmissions are subject to interception by any other radio receiver. That is
why you would use any encryption available for your wireless network and
use the strongest possible!

Software Security -
There are different layers of security that software can provide for your
Local level security starts at the workstation.
- Setting up a local user id and password is one way, low security.
- Using a Secure Card for access to the local workstation, medium security.
- Having a local domain with the security that a domain controller provides
is the better security.
- Using both the Secure Card reader and domain log on is the highest security.
- There is only one step above this and that is to encrypt the workstation hard
Local level security for your network.
- Setting up a local network with a domain will provide you with medium to high
- To gain access to a local workstation a user must be authenticated by the
- Authentication is a user id created and maintained by the domain controller
and a password.
- To increase security on a domain various things can be done, such as
enforcing password complexity, encrypting the password, insuring the password
is changed with a given schedule, and lock out of the user id after a certain
number of attempts that have failed..
Wired or Wireless a scenario:
04/09/14 - When I used a netbook to setup my
VPN Server I ran into a small problem. Like a firewall / proxy server I
needed two dissimilar network cards. The netbook has one wired NIC and one
wireless NIC, but it only has two USB ports. Rather than buying a USB NIC I
decided to use the wireless connection for the WAN side of the VPN server and
the wired connection for my LAN. This is not the best solution but is is a
cheaper solution. The VPN server is only powered up when we travel. At
sometime in the future I will purchase a USB NIC for the WAN connection and
disable the wireless NIC to increase the security of the VPN Server.
