3. Introduction of iot
• What Is IoT?
• The Internet of Things (IoT) describes the network of
physical objects—“things”—that are embedded with
sensors, software, and other technologies for the
purpose of connecting and exchanging data with
other devices and systems over the internet.
5. Definition of
IoT Security
What is IoT Security ?
IoT security is the act of securing Internet of Things
devices and the objects and everything which is
connected through internet from attackers.
6. Importance of
iot security
• It is very important to secure Iot devices from the
attackers or hackers.
• Hardware, software and connectivity will all need to
be secure for IoT objects to work effectively.
Without security, any connected object or device can be
hacked easily.
• Once hackers gain control, they can perform any activity
and steal the user's digital data.
8. Key elements
of iot security
1. Authentication - It helps to build trust between the
identity of IoT machines and devices to protect data and
control access.
2. Access Control - It is a security technique that
regulates who or what can view or use resources in a
computing environment
9. Key elements
of iot security
3. Data Security - to the process of protecting data
from unauthorized access and data corruption
throughout its lifecycle.
4. Non Repudiation - is the assurance that someone
cannot deny something.It means that the data receiver
cannot deny that he or she have not received the data
yet.
10. Key elements
of iot security
5. Data availability - means that information is
accessible to authorized users. It provides an
assurance that your system and data can be accessed
by authenticated users whenever they're needed.
11. Problems of
iot security
1. Hijacking Of IoT Devices - IoT devices that have weak
security measures can become a target of attackers and
attackers performs many attacks to hijack them.
2. Insufficient Testing And Lack Of Updates - One of the
security issues with IoT devices is that companies
producing them are often too careless when it comes to
proper testing and providing timely software updates.
12. Problems of
iot security
3. Botnet Attacks - a hacker creates an army of bots by
infecting them with malware and directs them to send
thousands of requests per second to bring down the
target.
4. Lack Of User Awareness - IoT is new technology,
so the users are not so much aware about the threats
of the IoT security.
13. Problems of
iot security
5. Issue of default passwords – many devices are
comes with the default passwords, which will be easily
guessed by the bruteforce attacks.
6. Remote vehicles access – hijack of your car is
also one of the threat possessed by the IoT. A skilled
hacker might hijack by getting the access of your
smart car through the remote access.
14. Solutions of
iot security
1. Change passwords often and make them
strong -
Changing passwords, on a regular basis, on internets
accounts, computers and mobile devices is a norm
nowadays.
2. Don’t connect insecure networks - It is unsafe
to connect your devices to insecure networks because attackers
might steal your data, passwords and sensitive information.
15. Solutions of
iot security
3. Update firmware timely – updates installs security
patches on your devices and stops hackers or attackers to
gain access of the system.
4. Don’t rely on cloud technology – Cloud
technology is very convenient for sure, but it is also a
quite vulnerable emerging technology prone to attacks.
16. Solutions of
iot security
5. Strong physical security – Providing physical security
means, to keep the IoT devices and objects at safe place
so that no one can breach sensitive information and
informational data.
6. Use Private Networks – always connect to private
networks only and create unique passwords for that
connection.
17. Attacks in
iot security
1. Botnet Attack - A botnet is a network that combines
various systems together to remotely take control over
a victim’s system and distribute malware.
2. Denial of service Attack(DOS) - A denial-of-service
(DoS) attack deliberately tries to cause a capacity
overload in the target system by sending multiple
requests.
18. Attacks in
iot security
3. Man-in-the-Middle Attack - In a Man-in-the-Middle
(MiTM) attack, a hacker breaches the communication
channel between two individual systems in an attempt to
intercept messages among them.
4. Social engineering Attack -Hackers use social
engineering to manipulate people into giving up their
sensitive information such as passwords and bank details.
19. Attacks in
iot security
5. Ransomware - In this attack, a hacker uses malware
to encrypt data that may be required for business
operations.
6. Advanced persistent threat - is a targeted cyber
attack, where an intruder gains illegal access to a
network and stays undetected.
20. Career in
iot security
The Internet of Things offers a range of career
opportunities in embedded systems cybersecurity,
software development, and more. Some of the top IoT
industries include healthcare, manufacturing, utilities,
transportation, agriculture, and consumer products. Jobs
are expected to increase in the coming years across
industries, though growth may be slower in some sectors
than others.
