The Internet of Things (IoT) is one of the most
active and fascinating innovations in information
and communications technology. Although
networking technologies have become more widely
used in recent years, they were formerly limited
to connecting traditional end-user devices such
as mainframes, desktop PCs, and, more lately,
smartphones and tablets.

The Internet of Things (IoT) refers to the
growing use of unique identifiers on objects and
entities (things) to send data across a network.
Computers, machine-to-machine (M2M)
communication, sensors, smart energy grids,
vehicle-to-vehicle communications, smart
buildings and homes, and wearable gadgets
contribute to the rise in IoT communication. Due
to this technological wave, more and more
elements of our lives are becoming connected to
the internet. Over 25 billion gadgets are
expected to be connected in the next few years,
and according to Forbes, the Internet of Things
business will rise greatly by 2025. All of these
connections are intended to improve our daily
lives, but when you consider that even your
television is collecting and transmitting your
personal data, things may become a little
frightening. The importance of the
IoT Influence is the most important aspect of
the IoT. Rather than simply exchanging data, the
Industrial IoT connects devices, systems, and
people in real-life environments like automated
factories, smart cities, and connected healthcare
to improve productivity. The Industrial Internet
of Things (IIoT) is described as the automated
interaction among smart devices and systems,
exchanging data to an offsite or cloud-based
solution for meaningful, time-sensitive analytics
using components that consume very little energy,
are easy to install and follow industry
standards. Traditional embedded systems, which
have grown from isolated systems to a network of
connected objects and systems, are at the center
of this phenomenon.

How secure is IoT? IoT entails connecting an
ecosystem of unconnected devices, resources, and
processes to the internet. With improved
computing capabilities and lower prices for
connectivity and data storage, the number of
linked devices is expected to reach 41.6 billion
by 2025, creating almost 79.4 ZB of data. The
rapid expansion of connectivity, on the other
hand, will expose IoT devices, sensors, and
platforms to significant security concerns. As
businesses attempt to integrate their old OT
systems with their IT systems correctly, numerous
IoT security frameworks have been developed to
reduce security breaches, data loss, and
financial losses. So, here are the steps to
securing the IoT devices in an organization. Enab
le device discovery for full visibility A
company should first determine how many IoT
devices are connected to its network. You should
determine which devices are connected to your
network and keep an inventory of all connected
assets, ideally using a dedicated IoT security
solution to ensure all devices are identified.
Take note of the device manufacturer, model ID,
serial number, software, firmware, and underlying
operating system and configuration. Analyze the
risk profile of each connected device in the
network and its behavior. Such profiles will help
with creating firewall policies and segmentation.
Whenever a new IoT device is connected to the
network, you should update your asset map.

Enabling network segmentation can be used for
stronger defense Segmenting networks is a
technique for allowing granular control over the
lateral movement of traffic among devices and
workloads within them. A single compromise event
is more likely to spread laterally in an
unsegmented network where many endpoints
communicate directly without any partitioning in
place. The more segmented a network is, the less
likely hackers are to be able to use a device as
a single point of concession to launch exploits
laterally. Use secure passwords Password-related
assaults on IoT devices continue to be fueled by
poor password security practices. Maintaining
robust password security is therefore essential
for securing your IoT devices. Many IoT devices
come pre-programmed with weak passwords that are
easily found online. It's excellent practice to
replace an IoT device's default password with a
safe, more difficult one as soon as it's
connected to your network. The new password
should be hard to guess, distinct for each
secured device, and follow the password standards
and management procedures of your IT security
team.

Always keep an eye on IoT devices Real-time
monitoring, reporting, and alerting are essential
for enterprises to manage their IoT risks.
Traditional endpoint security solutions cannot
secure IoT assets because they need software
agents that IoT devices cannot accept. Take a
more strategic approach. Implement a real-time
monitoring solution that integrates easily with
your current security posture and the next
firewall investment to continuously examine the
behavior of all your network-connected IoT
endpoints. Final words Connecting an ecosystem
of unconnected devices, resources, and processes
to the internet is what the Internet of Things
(IoT) is all about. Over 25 billion devices are
expected to be connected in the next few years.
Major security vulnerabilities in IoT devices,
sensors, and platforms will be exposed as the
connection expands rapidly. The number of IoT
devices connected to a company's network should
be determined, and all connected assets should be
inventoried. It's crucial to keep your IoT
devices safe by using strong passwords. Analyze
the risk profile and behavior of each connected
device in the network. If you are willing to
