Title: Blockchain in Cyber Security

Blockchain in Cyber Security

Cyber-security is one of the major concerns of
today's world. We can say no data is 100 safe in
the cyberworld. What we consider safe today may
not be helpful tomorrow. There are nearly 4.3
billion internet users today i.e. amounting to
nearly half of the population in the globe. And
it is predicted that there may be more of 6
billion users by 2022. More users more data
handling and security is needed. And most
companies and cybersecurity experts face a huge
risk in their path. It is anticipated that
cybercrime will cost the world of 6 trillion
every year by 2021, up from 3.6 trillion in
2016. Cyber attacks are increasing nowadays and
it is becoming more complex due to the
availability of more sophisticated malware,
creating a greater threat to many organizational
out their. Blockchain is considered as todays
security for the web world, still the critics are
into exploring its scalability, sustainability,
and security. However, the blockchains
capacities such as data confidentiality,
integrity, and availability surpasses all the
technologies already existing. Blockchain is now
considered as a viable technology when it comes
to data security and business transaction.
  • Here are some of the most prominent uses cases
    and solutions from blockchain to increase
  • Safe DNS
  • Domain Name System (DNS) is largely centralized.
    It makes easy for hackers to get into the system
    and make a connection through websites and IP
    address. By this they are able to crash the
    system, can steal data or redirect to scam
    websites. With this the attack it is also
    possible to pair DNS attacks with DDoS attacks
    and can lead to render an unusable website.
  • A blockchain system can create a security level
    to another level. As it is decentralized, it will
    make difficult for hackers to find an exact hack
    point. Every data and other domain information
    are stored in a distributed immutable ledger, and
    it is safeguarded by powerful smart contracts.
  • Decentralized Storage Solutions
  • Data security and the efficiency of data has been
    a serious problem for the organization and
    individuals around the world.

Storing the data is not a real issue but keeping
it in a secure manner is a great challenge.
Centralized storage are always vulnerable to
security breaches, makes it's unsuitable for
data security nowadays. Blockchain is an ideal
solution for the centralized storage solution. In
order to store the data, Blockchain uses
distributed ledger technology. It is very secure
since it uses modern cryptography hashing
algorithm to store data. Blockchain-based cloud
storage allows one to store data securely with
utmost efficiency and clear transparency on a
network. Blockchain solution provides full
control of data with utmost privacy and security
by using the latest data encryption methods. For
eg Friend an open-source community that is
powered by blockchain technology and is built to
provide much better solution for data security.
This platform provides digital freedom to
internet users. This cloud computing setup
provide much control and security than their
centralized server system
Security to Internet of Things(IoT) Devices IoT
security is one such area that is largely
concerned with safeguarding and it provides
network security to the connected devices on the
internet. IoT devices help hardware devices to
connect to the network and transfer data to
better performance of the device. Allowing
devices to connect to the internet will allow
them to connect to a more vulnerable system which
can lead to serious attacks if the device is
centralized and not properly maintained or
protected. DLT can be used to protect IoT from
attackers. IoT devices can be smart enough to
maintain security without relying on a
centralized system. For instance, consider some
device that can take part in a group which
creates a common consensus regarding how the
network to transfer data if anything suspiciously
or any node work against consensus will lock or
remove from network. By keeping the IoT device in
blockchain can let the device to attain a
real-time data transfer and real-time
communication between any devices from anywhere.
Private Data Security with DLT More popular
internet becomes, a lot of huge data, metadata is
collected from each user during each
transaction(on each activity). For instance,
suppose a customer uses social media and share
his/her like on some product, the real-time data
is watched by other users and they are able to
track that and use it for their own monetary
benefits and other purposes. Many social media
started to use end to end encryption to protect
the data being transferred. Currently, most
social apps and messaging services are missing a
standard set of security protocols, also they
use single platform API for enabling
cross-communication. By using blockchain for
communication, transmitting messages is via
creating a unified ecosystem. The main key factor
of using blocking in cyber security is that it
can provide a secure decentralized platform. When
data is no longer coming from a single point and
is secured by certain consensus and crypto
encryption, it makes it much more difficult for
the cyber crime activities.
