Wi-Fi is not the only wireless technology.
Wireless has a long history behind it.
The first develop technology was the analog network known as CD EPD this cordless data transmission
method is practically discarded today.
The successor of CPD to press is on the other hand still employed in a variety of applications.
It is now mostly used in mobile web browsing services.
The technology is still so used by the protocol and other wireless technology that is extremely popular
today is Bluetooth but even given this notoriety it is virtually unsecured.
All laptops and smart phones today have a built in Bluetooth connectivity this technology is freely
available and the technologies that make possible the interception of data sent over this channel are
equally available.
The slide above shows pictures of three such tools to secure your transmissions.
You can only force the encryption of exchange data.
Other than that the natural security is provided by the short maximum range of Bluetooth or a distance
of 10 meters.
We assumed that in the 10 meter radius there are no attackers who'd want to capture the data exchange
between the smartphone and the laptop.
For example during the synchronization of an address book
RFID is another wireless technology is spread over the world.
It can be encountered mostly in supermarkets and other shops.
The standard is used to tag products reading tags discloses the information contained in RFID is practically
unsecured.
The only protection involved assumes that a person who scans an RFID code is authorized to do it.
This doesn't always have to be the case.
Mentioned that if a thief of an RFID reader takes it to walk around a supermarket car park coming closer
to the cars he's able to view the bought items that are inside RFID is wide popularity does not ensure
it is safe.
You should remember that there are risks and threats connected to this technology that might be exploited
by attackers The same is true of near-field communication NFC.
It's usually used in an active passive communication mode.
This means that a near-field communication plan doesn't have the power source of its own NFC.
Clients include for example the increasingly popular proximity cards.
