00:00:00,470 --> 00:00:03,250

<v ->We all use wireless devices these days.</v>



2

00:00:03,250 --> 00:00:06,640

Whether it's your laptop, your tablet, or your smartphone,



3

00:00:06,640 --> 00:00:09,980

all of these have the ability to communicate wirelessly.



4

00:00:09,980 --> 00:00:12,370

How can we best secure these devices?



5

00:00:12,370 --> 00:00:14,660

Well, there's two main things we have to think about when



6

00:00:14,660 --> 00:00:17,010

we talk about wireless with these devices:



7

00:00:17,010 --> 00:00:19,340

Wi-Fi and Bluetooth.



8

00:00:19,340 --> 00:00:22,260

First, Wi-Fi, is there Internet connectivity?



9

00:00:22,260 --> 00:00:25,760

If we're using Wi-Fi, we want to make sure the Wi-Fi is set



10

00:00:25,760 --> 00:00:28,090

to be protected at the highest levels.



11

00:00:28,090 --> 00:00:31,350

Currently, that's WPA2, or Wi-Fi Protected



12

00:00:31,350 --> 00:00:33,070

Access Version Two.



13

00:00:33,070 --> 00:00:35,420

This relies on the advanced encryption standard



14

00:00:35,420 --> 00:00:38,173

for its encryption algorithm, also known as AES.



15

00:00:39,260 --> 00:00:42,320

In addition to securing our Wi-Fi, we also have to consider



16

00:00:42,320 --> 00:00:45,020

the peripherals that connect to these devices.



17

00:00:45,020 --> 00:00:47,420

For example, if you have a smartphone and it connects



18

00:00:47,420 --> 00:00:51,210

to a Bluetooth to your car, how is that link being secured?



19

00:00:51,210 --> 00:00:54,830

Well, by default, Bluetooth requires you to pair the device



20

00:00:54,830 --> 00:00:57,160

and when you pair the device, the two devices will



21

00:00:57,160 --> 00:01:00,180

communicate via that shared link in giving each other



22

00:01:00,180 --> 00:01:01,630

a shared link key.



23

00:01:01,630 --> 00:01:04,300

They use that key to encrypt their data.



24

00:01:04,300 --> 00:01:07,470

Unfortunately, some of these devices use weaker encryption



25

00:01:07,470 --> 00:01:09,670

than others, so if you're really worried about



26

00:01:09,670 --> 00:01:12,490

your confidentiality, you should always try to avoid



27

00:01:12,490 --> 00:01:14,470

wireless devices, when possible.



28

00:01:14,470 --> 00:01:17,280

If you have to use a wireless device like headphones



29

00:01:17,280 --> 00:01:19,650

or connecting to your car, you should look



30

00:01:19,650 --> 00:01:22,830

at the manufacturer specifications to determine what type



31

00:01:22,830 --> 00:01:26,110

of encryption is being used and if they're not using AES



32

00:01:26,110 --> 00:01:28,900

with a strong key, you might want to pass on using that



33

00:01:28,900 --> 00:01:31,317

device and buy a replacement.
