Until now we have seen how an address IP can be a very dangerous track
to leave when browsing the web; any server in this world is able
to log and store a visitor's IP address and associate it with any actions he performs.
Hide an IP Address (in computer jargon, spoof an IP) is not enough to cover up
the activities of an Internet user in the network: just think that any request not
encrypted can be monitored not only by governments but also by the ISP (Internet Service
Providers, or the network providers), but also by other services and malicious
of any type.
We have just introduced the HTTPS protocol, the new way in which computers are starting
to communicate within the web. encryption Data is having an increasingly important role
IT ecosystem and protocols sure they are replacing the weaker ones
(SSH -> Telnet, SFTP -> FTP, HTTPS -> HTTP and so on). So, unless the program
we use or proxy to which we are doing reliance are not specifically encrypted,
all our operations within Internet are easily monitored.
A note pertaining to navigation WWW: if privacy and anonymity are your priorities
forget forever Google and related and point to the search engines that there
monitor as StartPage or DuckDuckGo. Because?
Take for example Youtube. Youtube is a service purchased and operated by Google
and Google, we know, track anything. Youtube takes note of what your IP and
which video you are viewing, then throws down a user profile called fingerprint and knows
already know what you like to see next or maybe buy while you visit websites with Google
Adwords. A vicious circle.
We have seen how the proxies are tools votes but due to a series of problems
they can not guarantee us the right balance between safety and speed. I'll tell you more:
navigate with an open proxy is now virtually impossible, as well as insecure! Rates of
incredible latency and sudden down make it unusable for longer operations
of 5 minutes! Many believe that the VPN Proxies are the future. Is it true? Let's go
to find out.
VPN (short for Virtual Private Networks) are the "tunnel" encrypted that, exactly
as proxies, perform a liaison between clients and servers; This means that all traffic
Internet goes through this encrypted tunnel, preventing anyone to monitor the connection.
VPNs are originally designed to create a computer connected via LAN
Internet, just like a physical network, but did not address all of the costs involved
(Localization of the devices, connections physical etc ...) and with all the precautions
Safety of the case as Firewall, Proxy and so on. Using a VPN we will not
nor worry of finding working lists or to find specific types of protocols:
all traffic that travels over a VPN is transmitted and encrypted with quality standards
normally guaranteed to at least 128 bits.
The main advantage compared to a proxy is the high reactivity that the VPN often
guarantees; the architecture of such infrastructure and the geolocation server allows
to optimize the requests to the Internet network; also you do not need to reconfigure browser
and tools to be anonymous as tunneling - Generally - it is carried out throughout
the system.
In the VPN market we can define at least three types of VPN: VPN Trusted, Secure VPN and
Hybrid VPN. In this chapter we will discuss the
Secure VPN as the Trusted require Special contracts with ISPs and are not
easily applicable in public reality: the latter are in fact almost think
exclusively for corporate networks where It must ensure that the information arrives
always to the recipient.
The Hybrid are the union of the Trusted and Secure, and since we will not talk of
first, also we will exclude the latter. it that actually determines the quality of
security of a VPN - besides of course the policy and the stability of services that we will see
at the end of chapter - are both the types of protocols provided, both the safety of the covered keys.
Often not enough to speak of VPN to be sure: for example, until a few years ago
known VPN Ipredator providers only offered connectivity via PPTP: This
protocol type was already under suspicion of not 100% sure as decommissioned
from Microsoft (who invented and patented) and we are almost sure that espionage
government is already able to crackarlo in a short time. This is one of many examples
we have highlighted but we see the protocols one by one and pull the money on their characteristics
and quality.
PPTP (acronym for Point-to-Point Tunneling Protocol) was developed by
Microsoft for creating VPN corporate networks via the telephone dial-up connection.
It is a protocol designed exclusively for VPN and generally relies on MS-CHAP
for handling authentication. being It was for years a very popular tool
today is easily installed (or even pre-installed) at any device on
market and is also very rapid because It requires few resources for its operation.
PPTP, which can only support based 128-bit keys, began to yield
the vulnerability shots enough to force in 2012 Microsoft to declare it unsafe,
although the latter had released dozens of patches to ensure the situation.
This protocol is now considered insecure and surely already it violated the NSA but
useful for low-latency activities like gaming online, torrent, streaming etc ...
L2TP (short for Layer 2 Tunnel Protocol) It is a type of VPN protocol that basic does not
It provides no data security; this is why it is often accompanied
from a suite called IPsec. L2TP / IPsec It is then a mix of tunneling protocol
and already implemented in encryption systems Operating the latest generation, allowing
so easy configuration via clients and good overall speed.
Currently no known vulnerabilities relatively severe for this protocol
so I can recommend it to you if you want to keep a good level of privacy and security, however,
research conducted by two experts implies that the NSA is working diligently to
violate it.
Although this has not yet been tried, some sources confirm that IPsec is one
the main targets of the NSA and that theoretically an attack would be possible.
However, L2TP / IPsec provides encapsulation of the data in two steps with encryption keys
to 256 bits, making it technically facts slower than PPTP but thanks to the support
implemented in the kernel multi-threading latest generation allows you to encrypt and decrypt
exploiting the architecture of calculation of multi-core processors.
The only slight flaw in this protocol resides in the fact that the default L2TP
traveling on UDP port 500: the latter It is often blocked by the firewall business
and forces to carry out port-forwarding of routers and access points more sophisticated
(Raising questions about the browsing species in open networks).
With OpenVPN means a opensource software specifically designed to create encrypted tunnels
between two computer systems and that exploits cryptographic protocols based on SSL / TLS
and the OpenSSL library. The fact of being totally open warrant to this system
proper transparency to regard it as the most reliable and secure solution; currently,
there are very few risks that a spy agency government manages to violate it.
Its open nature makes it a product extremely configurable allowing us
to use it on any door without making port-forwarding (using eg
Also TCP port 443 to meet demands an HTTP over SSL) on the device
for your network. The library that uses (OpenSSL) can make use of different ciphers (such as Blowfish,
AES, DES, etc ...) however most of VPN providers make almost exclusive use
cipher AES or Blowfish. The latter, based 128 bits, is the cipher default
present in OpenVPN.
AES cipher is instead a relatively new and it is currently used by several governments
world to protect their data: being able to handle 128-bit blocks can
manipulate large information up to 1GB, unlike Blowfish that being based
64-bit it can only handle half. Compared to the IPsec protocol it turns out to be
much less fast and this can be deleterious species in those devices that do not
They have a lot of computing power: the cause of this slowness is the absence of a
native support for multi-threading then It does not allow to exploit the CPU of the new
generation on the market. Although it is not a de-facto standard as
previous PPTP and L2TP / IPsec, the market VPN provider has received with joy OpenVPN
and the developer community has released the client for all major Operating Systems,
including mobile devices.
(SSTP stands for Secure Socket Tunneling Protocol) is a tunneling protocol introduced
by Microsoft and native to all versions Windows from Vista onwards, while it is provided
but not pre-installed in Linux-based systems and BSD. At the moment there are no plans
reliable for the mobile world as well as for the more famous (except router firmware
Router-OS, currently the only system Operational for router that supports it).
As with OpenVPN makes use of cryptography based SSLv3 thus allowing the use of
encrypted tunnel even behind secure networks firewall; SSTP can be
used in conjunction with the authentication Winlogon or smartcard. He is currently the
security protocol used in the cloud Microsoft called Windows Azure. Unlike
OpenVPN is however a closed protocol and the PRISM scandal that has seen together
Microsoft and NSA is certainly no sleep quiet.
Well at this point we pull the money: what kind of VPN does for you? Well personally I
I feel to recommend a OpenVPN as it gathers all the features
we look for in a VPN, namely the best compromise between speed, security
and transparency of development. The only small problem will result in greater difficulty
respect to the installation and use other (as it is not present a function
built-in in almost any Operating System) However, every society in most
cases provides sufficient documentation to solve all the problems in the setup and
in the days to come. L2TP / IPsec is also very popular and unless you live in
more complete paranoia, ensures excellent speed and good overall safety.
Honestly I would advise against PPTP and SSTP: the first is definitely outdated and
risk doing more harm than good, the second It is better suited to the corporate world that does not
anonymity.
Arrived at this point it would be appropriate make yet another list of best online VPN.
But, as we have already done for the proxy, we'll just give directions on what
VPN is the right one for you based on the characteristics We are looking for, then kick you down a list
the most popular VPN with an overall summary.
Maybe you'll be asked: VPNs are free or paid? The answer is both, however,
I want to clarify that from here on out I will discuss only VPN paid. Because?
Some of the best VPN services as HideMyAss, NordVPN ExpressVPN offer or something like
more than 1000 servers located throughout the world. And think, these cost servers! Coast
keep them, replacing them costs when they break, manage costs. And unless you do not believe
which in this world is full of benefactors that they spend hundreds of thousands of dollars
per month to keep them do not trust the VPN Free!
But how do you earn a VPN? Simply may sell your information. I'm not talking
usernames and passwords (even if it is not said!) but of real honeypot used for
making statistical and sell them to the highest bidders.
Once you're in the circuit you are part of the Virtual network, then automatically become
"Accomplice" of the network; this means not only your Internet goes slower
(This was obvious), but you can end up the "tail end" and be the
responsible for a practice to be incorrect other users.
This is a practice much in vogue in the world of free proxy as in that of the free vpn.
Adware present in the Free VPN can either be installed along with the client
be shown during navigation manipulating the source of the Web pages you're going to
display.
When you purchase a service protected by six a document that will automatically accept both
you that the selling company: This document is called Terms and Conditions of Use which,
together with the Privacy Policy, form the document legal that establishes the relationship between the two.
In the case of Free VPN these documents are often confused and being free you
think: oh well, who cares as long as it's free! In fact, as we will see shortly the ToS and
Privacy are of paramount importance for have a quality VPN that guarantees
efficiency and safety in navigation.
Now you understand that those spending € 9 per month (More Euros Euros less) can make a real
difference?
The logs are files that are generated for each activity carried out within
of a computer system: in the case of VPN, the log can store information
such as IP, data access, and other information that are not encrypted before the handshake
(Which will lead to tunneling real and then the total encryption).
If you're choosing a VPN logless not limit the advertising slogan, but controls the Privacy
Policy declared by the provider.
Imagine you are a business owner VPN provider, and in the middle of the night you
knocks on the FBI (or the CIA, the police or who I think) with a search warrant of
Data of your server. Are you to do the champion of justice and defend
a stranger on the other end of world has started playing with computers
a corporation? The answer, needless to say, it is of course not! there is no
VPN providers that would risk years in prison for you. There is no benefactor of this
Typically, therefore always remember that the provider always does its interests and with the right
pressures is willing to sell (as in If HideMyAss).
The key then is to understand that a provider VPN can not release information about you
that does not have, so they can not be prosecuted for not having cooperated by giving information
that - the facts - do not have. normally a VPN providers solicit personal information
to create accounts and process payments, then ask: name, email, payment information
and billing addresses.
Best VPN providers have lately realized that it is possible to allow for more
anonymity to its users by offering them payments with cryptomonete (which will be discussed
in there): this still allows, with precautions, to make the anonymous
purchase of service by lifting sellers weighing store billing information.
