1
00:00:02,730 --> 00:00:05,910
Wi-Fi is not the only wireless technology.

2
00:00:05,910 --> 00:00:07,980
Wireless has a long history behind it.

3
00:00:09,620 --> 00:00:16,500
The first develop technology was the analog network known as CD EPD this cordless data transmission

4
00:00:16,500 --> 00:00:20,320
method is practically discarded today.

5
00:00:20,480 --> 00:00:28,470
The successor of CPD to press is on the other hand still employed in a variety of applications.

6
00:00:28,520 --> 00:00:32,560
It is now mostly used in mobile web browsing services.

7
00:00:32,570 --> 00:00:40,840
The technology is still so used by the protocol and other wireless technology that is extremely popular

8
00:00:40,840 --> 00:00:47,010
today is Bluetooth but even given this notoriety it is virtually unsecured.

9
00:00:48,900 --> 00:00:55,700
All laptops and smart phones today have a built in Bluetooth connectivity this technology is freely

10
00:00:55,700 --> 00:01:02,160
available and the technologies that make possible the interception of data sent over this channel are

11
00:01:02,190 --> 00:01:03,320
equally available.

12
00:01:05,130 --> 00:01:09,790
The slide above shows pictures of three such tools to secure your transmissions.

13
00:01:09,810 --> 00:01:14,450
You can only force the encryption of exchange data.

14
00:01:14,580 --> 00:01:20,190
Other than that the natural security is provided by the short maximum range of Bluetooth or a distance

15
00:01:20,190 --> 00:01:23,520
of 10 meters.

16
00:01:23,520 --> 00:01:28,380
We assumed that in the 10 meter radius there are no attackers who'd want to capture the data exchange

17
00:01:28,380 --> 00:01:31,330
between the smartphone and the laptop.

18
00:01:31,510 --> 00:01:34,210
For example during the synchronization of an address book

19
00:01:37,020 --> 00:01:40,690
RFID is another wireless technology is spread over the world.

20
00:01:42,520 --> 00:01:46,100
It can be encountered mostly in supermarkets and other shops.

21
00:01:46,120 --> 00:01:54,870
The standard is used to tag products reading tags discloses the information contained in RFID is practically

22
00:01:54,870 --> 00:01:57,780
unsecured.

23
00:01:57,820 --> 00:02:03,360
The only protection involved assumes that a person who scans an RFID code is authorized to do it.

24
00:02:05,890 --> 00:02:07,930
This doesn't always have to be the case.

25
00:02:08,780 --> 00:02:15,900
Mentioned that if a thief of an RFID reader takes it to walk around a supermarket car park coming closer

26
00:02:15,900 --> 00:02:23,360
to the cars he's able to view the bought items that are inside RFID is wide popularity does not ensure

27
00:02:23,360 --> 00:02:24,250
it is safe.

28
00:02:26,350 --> 00:02:30,820
You should remember that there are risks and threats connected to this technology that might be exploited

29
00:02:30,820 --> 00:02:38,580
by attackers The same is true of near-field communication NFC.

30
00:02:38,640 --> 00:02:41,980
It's usually used in an active passive communication mode.

31
00:02:42,830 --> 00:02:48,400
This means that a near-field communication plan doesn't have the power source of its own NFC.

32
00:02:48,410 --> 00:02:52,310
Clients include for example the increasingly popular proximity cards.
