Wireless

Sorry newbie question, can wireless networks be detected from a regular
wired 'grounded' network machine?...or does the machine your using have to
be on a wireless network in order to detect other wireless networks? Thanks
in advance.

You need a wireless adapter to detect wireless networks. Whether you are
connected to a network, wired or wireless, is not relevant.

Wireless = radio. You need a radio receiver (and a transmitter) to
interact with a wireless network.

Thanks for the info Lem, appreciate it. Another newb question, can wireless
network monitoring software then track one's wireless activity when say
browsing the internet and sending/receiving personal emails from their own
cell phone device with one's own cell phone carrier?

"Wireless" is a very broad term. Without context, all it means is the
transfer of information without wires.

In the context of computer networking, "wireless" usually means
communication that complies with IEEE standard 802.11
(http://en.wikipedia.org/wiki/802.11). This uses relatively short-range
low-power radios. The term "WiFi" is a trademark of an alliance of
manufacturers of equipment used for home wireless networks that comply
with various parts of IEEE 802.11.

Cell phones use a different radio technology. Newer cell phones (e.g.,
the iPhone) may incorporate both cell phone and WiFi connectivity in a
single device.

Any radio communication, including WiFi network traffic and cell phone
calls, can be detected and intercepted by someone with the proper radio
receiver. For this reason, both cell phone and WiFi network
transmissions may be encrypted for security. In the case of digital cell
phones, the encryption (and other security technology) is configured by
the cell phone manufacturer and/or the carrier. That is, the user isn't
involved. In the case of WiFi networks, the default is to leave the
transmission unencrypted (and thus easily intercepted and monitored).
Whether to use encryption, and if so, what level of encryption, is left
to the owner of each wireless network.

As you might guess, there are lots of individuals who try to break the
encryption protections of various wireless traffic. The first technology
used for home wireless networks, WEP, is now all but useless for
security. If you set up a wireless network today, you should use WPA2
encryption.

Similarly, cell phone encryption has reportedly been cracked:

Totally apart from eavesdropping on wireless transmissions, email sent
over the Internet is not secure. An email does not go directly from
point A to point B. Rather, it travels through a series of intermediate
servers, any one of which can view its content. For this reason, people
who are concerned about the security of their email often use some form
of encryption to secure their messages.

Hi
Any Wireless signal can be intercepted while it is in the Air.
If the information that is in the signal is Not encrypted it can be easily
used by others.
Wireless Telephones encrypted the signal by default.
Wireless computers have to be set to encrypt the signal.
In general.
From the weakest to the strongest, Wireless security capacity is.
No Security
Switching Off SSID (same has No Security. SSID can be easily sniffed even if
it is Off)
MAC Filtering______(Band Aid if nothing else is available, MAC number can be
easily Spoofed).
WEP64____(Easy, to "Break" by knowledgeable people).
WEP128___(A little Harder, but "Hackable" too).
-------------------
The three above are Not considered safe.
Safe Starts here at WPA.
-------------------
WPA-PSK__(Very Hard to Break).
WPA-AES__(Not functionally Breakable)
WPA2____ (Not functionally Breakable).
Note 1: WPA-AES the the current entry level rendition of WPA2.
Note 2: If you use WinXP bellow SP3 and did not updated it, you would have
to download the WPA2 patch from Microsoft.
http://support.microsoft.com/kb/893357
The documentation of your Wireless devices (Wireless Router, and Wireless
Computer's Card) should state the type of security that is available with
your Wireless hardware.
All devices MUST be set to the same security level using the same pass
phrase.
Therefore the security must be set according what ever is the best possible
of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the
max. with WPA2, but one device is only capable to be configured to max . of
WEP, to whole system must be configured to WEP.
If you need more good security and one device (like a Wireless card that can
do WEP only) is holding better security for the whole Network, replace the
device with a better one.

So when using a Windows Mobile 6.1 device is used as 'tethering' a single pc
with a cell phone carrier's service then assuming the obvious that the
signal can be detected when monitored by a wireless software detection tool
(from a different machine on a different network within it's proximity)
would it be up to the cell phone carrier if it's encrypted or is there a
setting on the cell phone device that lists it? Thanks to both, very
interesting.

Thanks also Miguel. Would tethering or use the 'phone as modem' feature on
the cell phone device on machine 'A' be detected from another different
machine 'B' wireless software monitor and be considered a rogue access point
even though machine 'A' like mentioned is using it's own cell phone
service's network plan only and not trying to enter the other machine 'B's
network?

You cell phone can pick up two types of wireless :

1. The type that connects to cell phone towers (I think its GSM but
that's not my field). There are tools that just became available to
hack the sugnal which has been around since the 80's and is in need of
update. So, phone calls and data can be intercepted.

2. Wireless Frequency like B+G which you use to log into hotspots, or
home wireless routers also have encryption algorithms that can be
hacked. Also, many phone loke BB and IPhone have radios that can use
these types of wireless signals. If you, for example, log into you
local neighborhood's unsecured wireless, you take the risk that that
person has a sniffer and is listening in and looking at your plain
text data (ouch!). The same can happen at work, if the IT manager has
a gateway device that logs usage (like an IP filter) he can usually
track traffic back to your phone. But that all depends on the
equipment that is in place.

Hi
When a telephone is used as a Modem the Tel. transmission to the Cell tower
is Encrypted.
However once it is fed to a regular computer what ever is going on between
the computers is not any more Tel. activity it is regular WIFI, and thus as
to be dealt with as mentioned in my previous post.
