The document discusses fundamentals of IoT security. It defines IoT as the interconnection of physical devices to the internet to share and exchange data. IoT security protects connected devices from cyberattacks by securing the network functionality and data privacy. The need for IoT security increased after hacking attacks showed catastrophic consequences. The document outlines eight principles of IoT security including no universal passwords, secured interfaces, proven cryptography, security by default, signed software updates, and a vulnerability reporting scheme.

4. What is IoT?
╸ IoT - Internet of Things
╸ Interconnection and network of various
devices formed by connecting any
physical device to the internet for
sharing and exchanging the data.
╸ Inter-Network of devices/things which
are connected to the internet/WWW.

5. What is IoT?
╸ The IoT infrastructure consists of mainly 4 basic modules:
• WSN or sensor Hub
• wireless connectivity solution
• cloud computing and storage solution
• user device Network
╸ IoT devices are used in multiple sectors and industries,
including:
• Consumer applications
• Business applications
• Governmental applications

What is IoT
Security?
• IoT security can be understood as a
cybersecurity strategy and protection
mechanism that safeguards against the
possibility of cyberattacks which
specifically target physical IoT devices that
are connected to the network.
• Without robust security, any connected IoT
device is vulnerable to breach, compromise
and control by a bad actor to ultimately
infiltrate, steal user data and bring down
systems.

Why IoT
Security?
• IoT is a representation of Connected World
• The sheer volume of Internet of Things
devices makes their security a high priority
and is crucial for the future wellbeing of the
internet ecosystem.
• Without robust security, any connected IoT
device is vulnerable to breach, compromise
and control by a bad actor to ultimately
infiltrate, steal user data and bring down
systems.

8. The need for IoT security solutions is supported by two primary cases:
• Securing the functionality and digital perimeter of a network
• Data privacy
IoT security wasn’t really taken seriously until recently after many
hacking attacks resulted in catastrophic consequences.
