00:00:00,320 --> 00:00:07,439
in a perfect world a browser cookie would be something sweet and delicious

2
00:00:04,880 --> 00:00:11,400
that Chrome Firefox or Edge would shoot out of the screen so that you could

3
00:00:09,240 --> 00:00:15,839
enjoy filling up on empty calories while you watch Techquickie but tragically we

4
00:00:13,880 --> 00:00:21,400
don't live in a perfect world and in a Computing context the term Cookie

5
00:00:18,119 --> 00:00:24,240
doesn't refer to free desserts instead

6
00:00:21,400 --> 00:00:28,439
cookies are actually small files stored in your browser cache that can do a

7
00:00:26,160 --> 00:00:33,719
number of useful things but have also been scrutinized for potentially

8
00:00:30,720 --> 00:00:38,160
compromising user privacy so how exactly do these things work and why the heck

9
00:00:35,719 --> 00:00:43,039
are they even called cookies the name actually comes from Magic Cookie which

10
00:00:40,879 --> 00:00:48,039
was an early term for a small piece of data passed between computers usually

11
00:00:45,440 --> 00:00:53,120
for identification purposes modern browser cookies also identify your

12
00:00:50,520 --> 00:01:00,079
computer but they serve the additional purpose of tracking your activity which

13
00:00:56,719 --> 00:01:02,760
actually isn't always as nefarious as it

14
00:01:00,079 --> 00:01:07,240
sounds the way it works is that when you visit a cookie enabled site for the

15
00:01:04,760 --> 00:01:13,040
first time let's say Amazon the site will put a cookie on your computer that

16
00:01:09,119 --> 00:01:15,680
contains a unique ID Amazon uses this ID

17
00:01:13,040 --> 00:01:20,200
to keep track of your session so that the site knows which shopping cart is

18
00:01:18,159 --> 00:01:24,640
yours and what you've looked at so it can suggest stuff like toilet paper to

19
00:01:22,799 --> 00:01:29,960
you if you were browsing for industrial siiz packs of microwave burritos session

20
00:01:27,759 --> 00:01:34,000
management with cookies has many more applications though than just virtual

21
00:01:31,840 --> 00:01:38,320
shopping carts the identifier in a cookie can allow a server to keep track

22
00:01:36,320 --> 00:01:42,000
of your login so you don't have to keep punching in your password every time you

23
00:01:39,960 --> 00:01:46,960
visit a site and it can remember how you've customized the layout or

24
00:01:44,200 --> 00:01:51,840
appearance of a page previously cookies also allow sites to figure out how many

25
00:01:49,280 --> 00:01:56,200
unique visitors they get since each unique visitor has their own ID

26
00:01:54,360 --> 00:02:00,759
contained within a cookie which is important for web Masters who need

27
00:01:58,280 --> 00:02:05,320
analytics data for business development okay lonus I get that

28
00:02:02,880 --> 00:02:10,200
cookies make things more convenient but I heard they can also make me fat I mean

29
00:02:07,399 --> 00:02:14,680
spy on me what's the deal with that well one of the most common ways that your

30
00:02:12,080 --> 00:02:19,760
browser can compromise your privacy is by allowing third party cookies which

31
00:02:17,440 --> 00:02:24,959
are sent from sites other than the one that you're visiting for instance banner

32
00:02:22,280 --> 00:02:29,160
ads are often hosted on a different domain than the one that you're actually

33
00:02:26,959 --> 00:02:35,319
browsing and can plant cookies on your computer that track you across multiple

34
00:02:33,239 --> 00:02:41,200
sites which many people find intrusive and downright creepy but even worse is

35
00:02:38,560 --> 00:02:46,120
the potential for cookie theft which is exactly what it sounds like usually

36
00:02:43,720 --> 00:02:51,599
super sensitive things like website passwords aren't stored in cookies but

37
00:02:48,519 --> 00:02:55,120
the identifier in the cookie can be used

38
00:02:51,599 --> 00:02:57,040
to essentially steal a logged in session

39
00:02:55,120 --> 00:03:02,000
meaning that an attacker could access your shopping cart bank account or even

40
00:02:59,360 --> 00:03:06,799
Medical records without even knowing your password and get this browsers

41
00:03:04,680 --> 00:03:11,959
usually just store your cookies in plain text without any encryption making them

42
00:03:09,400 --> 00:03:17,239
a vulnerable Target though using websites that transmit cookie data over

43
00:03:14,080 --> 00:03:19,200
a secure connection can help somewhat so

44
00:03:17,239 --> 00:03:24,440
what can you do then to mitigate these privacy risks well first of all most

45
00:03:21,840 --> 00:03:29,000
browsers will allow you to disable third-party cookies with a simple option

46
00:03:27,000 --> 00:03:32,920
so you'll only get cookies directly from the site that you're visiting and if you

47
00:03:31,280 --> 00:03:37,280
want to take it a step further you can disable cookies entirely if you don't

48
00:03:35,400 --> 00:03:42,879
mind missing out on the features that they offer number two is if you've got

49
00:03:40,319 --> 00:03:47,599
cookies on or even just in general be careful about what you click on and what

50
00:03:45,159 --> 00:03:52,319
sites you're browsing if you're only navigating to trusted sites that are

51
00:03:49,519 --> 00:03:56,480
going to not spy on you then no one will be spying on you although it's not

52
00:03:54,400 --> 00:04:02,120
always easy to tell who to trust these days and finally keeping the hard drive

53
00:03:59,319 --> 00:04:06,239
on your computer encrypted is actually a pretty key one because if someone walks

54
00:04:04,239 --> 00:04:11,400
off with your entire computer and all the cookies on it it's an easy way to

55
00:04:08,959 --> 00:04:17,000
have the bad guys putting their hands in your cookie jar so to speak and on the

56
00:04:14,720 --> 00:04:21,280
