virtual private networks or vpns for short are used today for many reasons
but all of them fall under the same general umbrella securely connecting an
individual client off in a PC to a larger server or provider now in the
past these types of connections were mostly used in business settings when a
large employer wishes to allow employees access to a secured internal network
over the Internet while working from home or in the field but it's becoming
more and more common now to see them used by even small businesses or even
individuals who for a range of reasons wish to keep their activities online
secure and private reasons that range from the completely understandable to
the legally Andor morally gray to the downright paranoid and delusional now
the first step of the security process for a VPN involves creating a tunnel
protocol which acts as well a tunnel or
conduit for the information packets being transferred to pass through it
creates a security layer which instantly terminates the connection whenever it
detects an intrusion and then reconnects the client back to the server using a
different route avoiding the compromised Point points or the entire previous
route alt together the next time around some Services even utilize highly
specified Roots which they consider to be lower risk than other ones usually
based on some sort of internally established metrics or a working
partnership with the operator now inside this protective hard chocolate tunnel is
where the gooey caramel and nougat Center or data can be found this data is
also encrypted as one might expect but on top of this further efforts are made
to ensure that the contents of one's email don't become public Sony anyone
Beyond standard encryption nonlinear transfer methods such as utilizing
multiple routes for the traffic or the introduction of dummy code into the
information packet prevents prying eyes from seeing anything but a small garbled
slice of the overall Pi so to summarize
the way a VPN security works I'll turn this into a classic analogy it's like a
taco inside a taco within a Taco Bell that's inside a KFC within a mall that's
inside your brain Okay then lonus if
data transfers happen in basically the same way that all other internet traffic
does while offering a tremendously higher level of personal protection and
the ability to access secure networks from abroad then there's no downside
right let's just use them all the time well actually basically yeah VP are
super cool but come on man these videos are pretty much a formula at this point
you know the other shoe was going to drop although some VPN companies have
made utilizing their service as easy as double clicking the correct icon and
beginning to Surf and they're getting more affordable than ever some pages and
services might not work correctly over a VPN and content loading performance can
be affected as well since encryption efforts coupled with what can be
considered less direct routes can lead to a slower overall experience in many
cases though this can be solved quite easily by keeping another stock web
browser installed on your computer for non-mission critical use and it's also
worth noting that many VPN users actually report faster speeds on certain
popular sites such as YouTube at peak times presumably because their traffic
is avoiding some of the congestion seen along the other traditional routes there
are some other less easily addressed problems too though in buildings with
shoddy wiring packet loss can look like the network is compromised causing the
connection to be continually dropped and reestablished and another is the widely
reported one where the NSA in the United States has actually been known to flag
accounts for using keywords related to accessing these Services meaning that
seeking out extra security could potentially open one up to intrusion
speaking of intrusion Dollar Shave Club you know the guys that walk past you
while you poop kick the door open to your stall while you poop and bother you
