Have
you ever thought about using an encrypted web browsing environment or securing your server
environment to prevent spying and man-in-the-middle attacks? If yes, then you
must know about DNSCrypt,
a protocol for securing communications, which enables a user to establish
strong DNS security
layers and prevents spoofing. The DNScrypt-proxy tool helps a user to encrypt
everything that is being transferred between the client and a DNS resolver. The
tool can easily act as a DNS forwarder, enabling a configured network to
authenticate incoming/outgoing traffic requests and passing them to an upstream
server.
Undoubtedly,
setting up DNS and
managing its security isn’t an easy task, but it is required every time you
access a website, send an email or engage in IM conversations. In a world where
every Internet user is relying on OpenDNS, DNSCrypt provides world-class Internet security by
protecting the ‘last mile.’ The ‘last mile’ refers to the distance of your
Internet connection between your computer and your ISP. Tech experts claim that
the new protocol will soon be a part of world’s Internet connectivity,
preventing serious security concerns and helping users to connect different
Wi-Fi networks.
Why You Need the New DNS Protocol?
If
you’re using Internet for years, then there is no point in explaining about why
and how you should encrypt inward/outward traffic. DNS attacks may result in serious cyber
crimes, engaging malware authors and hackers stealing your private and
confidential information. As SSL turns unprotected HTTP web traffic into HTTPS
encrypted traffic, similarly this protocol turns normal DNS traffic into an
encrypted traffic channel.
The
entire encryption process helps a user in countering eavesdropping and man-in-the-middle
attacks, resulting in establishing a strong and secure internet connection. The
best thing about this web browsing encryption tool is that it will not make any
changes to domain names or its functionalities. All it will do is to secure an
encrypted communication network between the customers and DNS servers to avoid
any serious data loss or hacking.
Simple Steps to Install DNSCrypt in Ubuntu
1.
Open the terminal in Ubuntu and run these
commands to install DNSCrypt:
·
sudo add-apt-repository ppa:shnatsel/DNScrypt
·
sudo apt-get update
·
sudo apt-get install DNScrypt-proxy
2.
Once the utility gets installed, click the
‘Network icon’ to open the network manager and select ‘Edit connections’ option
from the context menu
3.
A ‘Network connections’ window will open, now pick
your network connection and click on the ‘Edit’ button
4.
You will see
an additional options window, and you’ll need to switch to the ‘IPv4 settings’
tab to proceed further
5.
Change the ‘Automatic DHCP’ option to ‘Automatic
DHCP addresses only’ and enter the DNS IP address as ‘127.0.0.2’
6.
Or if you’re using a ‘Manual' method, then there
is no need to change the options, you can proceed by entering the DNS address
7.
Click the ‘Save’ button to make and save the
changes
8.
Now, restart your network connection or your
Ubuntu machine to bring the changes in action and enjoy secured web browsing
experience.
Conclusion
Once
you’ve enabled this DNSsecurity protocol, all your DNS communications will automatically get
encrypted to deliver a safer online experience. Always remember that installing
and setting up DNS
protocol will ensure that all your DNS requests get authenticated and approved
before they reach your PC. It is a must download utility for people using VPN
services as they won’t encrypt your incoming/outgoing traffic and may give rise
to severe online attacks. If you are really concerned about your online
security and privacy, then encrypt DNS traffic in Ubuntu using DNSCrypt to avoid
man-in-the-middle attacks and DNS hijacking!
