1
00:00:00,120 --> 00:00:07,040
virtual private networks or vpns for short are used today for many reasons

2
00:00:05,040 --> 00:00:12,799
but all of them fall under the same general umbrella securely connecting an

3
00:00:10,440 --> 00:00:16,680
individual client off in a PC to a larger server or provider now in the

4
00:00:15,160 --> 00:00:21,359
past these types of connections were mostly used in business settings when a

5
00:00:19,160 --> 00:00:26,000
large employer wishes to allow employees access to a secured internal network

6
00:00:23,800 --> 00:00:30,439
over the Internet while working from home or in the field but it's becoming

7
00:00:28,400 --> 00:00:35,600
more and more common now to see them used by even small businesses or even

8
00:00:32,759 --> 00:00:40,200
individuals who for a range of reasons wish to keep their activities online

9
00:00:37,360 --> 00:00:44,360
secure and private reasons that range from the completely understandable to

10
00:00:41,960 --> 00:00:48,879
the legally Andor morally gray to the downright paranoid and delusional now

11
00:00:46,879 --> 00:00:54,520
the first step of the security process for a VPN involves creating a tunnel

12
00:00:51,360 --> 00:00:56,559
protocol which acts as well a tunnel or

13
00:00:54,520 --> 00:01:01,000
conduit for the information packets being transferred to pass through it

14
00:00:58,320 --> 00:01:05,000
creates a security layer which instantly terminates the connection whenever it

15
00:01:02,559 --> 00:01:09,560
detects an intrusion and then reconnects the client back to the server using a

16
00:01:07,520 --> 00:01:14,360
different route avoiding the compromised Point points or the entire previous

17
00:01:11,680 --> 00:01:18,960
route alt together the next time around some Services even utilize highly

18
00:01:16,960 --> 00:01:23,079
specified Roots which they consider to be lower risk than other ones usually

19
00:01:21,600 --> 00:01:27,439
based on some sort of internally established metrics or a working

20
00:01:24,920 --> 00:01:32,200
partnership with the operator now inside this protective hard chocolate tunnel is

21
00:01:30,200 --> 00:01:37,320
where the gooey caramel and nougat Center or data can be found this data is

22
00:01:35,520 --> 00:01:41,840
also encrypted as one might expect but on top of this further efforts are made

23
00:01:39,680 --> 00:01:47,799
to ensure that the contents of one's email don't become public Sony anyone

24
00:01:45,640 --> 00:01:52,240
Beyond standard encryption nonlinear transfer methods such as utilizing

25
00:01:49,799 --> 00:01:56,240
multiple routes for the traffic or the introduction of dummy code into the

26
00:01:53,880 --> 00:02:02,039
information packet prevents prying eyes from seeing anything but a small garbled

27
00:01:59,039 --> 00:02:04,159
slice of the overall Pi so to summarize

28
00:02:02,039 --> 00:02:08,879
the way a VPN security works I'll turn this into a classic analogy it's like a

29
00:02:06,119 --> 00:02:13,840
taco inside a taco within a Taco Bell that's inside a KFC within a mall that's

30
00:02:10,759 --> 00:02:15,640
inside your brain Okay then lonus if

31
00:02:13,840 --> 00:02:19,560
data transfers happen in basically the same way that all other internet traffic

32
00:02:17,480 --> 00:02:23,400
does while offering a tremendously higher level of personal protection and

33
00:02:21,440 --> 00:02:27,840
the ability to access secure networks from abroad then there's no downside

34
00:02:25,480 --> 00:02:32,920
right let's just use them all the time well actually basically yeah VP are

35
00:02:30,400 --> 00:02:36,319
super cool but come on man these videos are pretty much a formula at this point

36
00:02:34,680 --> 00:02:41,000
you know the other shoe was going to drop although some VPN companies have

37
00:02:38,920 --> 00:02:44,000
made utilizing their service as easy as double clicking the correct icon and

38
00:02:42,519 --> 00:02:48,680
beginning to Surf and they're getting more affordable than ever some pages and

39
00:02:46,440 --> 00:02:53,080
services might not work correctly over a VPN and content loading performance can

40
00:02:51,040 --> 00:02:56,519
be affected as well since encryption efforts coupled with what can be

41
00:02:54,640 --> 00:03:01,200
considered less direct routes can lead to a slower overall experience in many

42
00:02:59,280 --> 00:03:04,640
cases though this can be solved quite easily by keeping another stock web

43
00:03:03,040 --> 00:03:09,159
browser installed on your computer for non-mission critical use and it's also

44
00:03:07,200 --> 00:03:13,959
worth noting that many VPN users actually report faster speeds on certain

45
00:03:12,040 --> 00:03:18,200
popular sites such as YouTube at peak times presumably because their traffic

46
00:03:16,440 --> 00:03:22,159
is avoiding some of the congestion seen along the other traditional routes there

47
00:03:20,280 --> 00:03:26,319
are some other less easily addressed problems too though in buildings with

48
00:03:23,920 --> 00:03:30,799
shoddy wiring packet loss can look like the network is compromised causing the

49
00:03:28,439 --> 00:03:35,840
connection to be continually dropped and reestablished and another is the widely

50
00:03:33,760 --> 00:03:40,120
reported one where the NSA in the United States has actually been known to flag

51
00:03:37,680 --> 00:03:44,200
accounts for using keywords related to accessing these Services meaning that

52
00:03:42,120 --> 00:03:49,879
seeking out extra security could potentially open one up to intrusion

53
00:03:47,319 --> 00:03:53,239
speaking of intrusion Dollar Shave Club you know the guys that walk past you
