The Internet of Things (IoT) hacking is the hacking of IoT devices. IoT is a network of devices embedded with sensors, software, and other technologies to connect and exchange data and information with other devices and systems over the Internet. It primarily refers to the fast-expanding network of linked devices that use embedded sensors to collect and exchange data in real-time. Although IoT hacking is a relatively new phenomenon, it has already shown a vast capacity for destruction in a relatively short period.

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.
Enable 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.

6. 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 learn more about the IoT and its security, check out
