Abstract - Internet of Things systems has fastly growing in
all over the world and major roles in daily life by providing
new capabilities to streamline diverse tasks. IoT provide the
new capabilities and creates opportunities for increased
productivity and societal benefits. IoT also provide the broad
area of functionality and components will result in important
challenges of privacy and security should beaddressed. Large-
scale, pervasive networks that receivethedatafromthe world.
Used new predictive technologies and algorithms that enable
IoT. Once the data collected from IoT devices and algorithms
that process this data andafterwordused fordecision-making.
IoT also presents new security and privacy challenges.
Sometimes it is more difficult todeploysecurityandprotection
schemes for IOT devices because with less functionality, less
processing power, minimum storage capacity etc. Such
deployments may need new protocols and system designsthat
are better implemented to operate in resource-limited
environments. Policy and technical approaches to show the
IoT privacy and security challenges should continue to
encourage innovation while ensuring that user trust in these

1. INTRODUCTION
Day by day internet technology and communications
technology are fastly growing; our life is gradually changed
into an imaginary space of virtual world. People can chat,
work, shopping, keeps pets and plants in the virtual world
provided by the network. To eliminate this impulsion,a new
technology is required to sum-up the imaginary space and
real-world on a same platform which is called as Internet of
Things (IoTs). Based on a large number of low-cost sensors
and wireless communication,thesensornetwork technology
puts forward new demands totheInternettechnology.It will
bring huge changes to the future society, change our way of
life and business models.
There are several security and privacy concerns at different
layers viz; Front end, Back end and Network. In this paper is
to present the study of security and privacy issues in
Internet of Things (IoTs) and by present some challenges.
2. LITURATURE REVIEW
J. Sathish Kumar et. al. [1] presents the Internet of Things
with architecture and design goals. They show the security
and privacy concerns at different layers in IoTs. In addition,
they identifiedseveral open issues relatedtothesecurityand
privacy that need to be addressed by research community to
make a secureand trusted platform for the delivery of future
Internet of Things. They alsodiscussedapplicationsofIoTsin
real life.
Sivarama Subramanian et. al. [2] introducing security in
the early life cycle of the IoT solution can make mitigation
design much easier. Security and privacy challenges for any
IoT solution can be addressed by following secure systems
development life cycle (SDLC) practices, secure coding
practices and periodic penetration testing activities.
Zejun Ren et. al. [3] analyze the privacy and security
challenges in the IoT and survey on the corresponding
solutions to enhance the security of IoT architecture and
protocol. They should focusmore on the securityandprivacy
on IoT and help to promote the development of IoT.
Shervin Erfani et.al. [4] analyzesdistinctIoTsecurityand
privacy features, including security requirements, threat
models, and attacks from the smart home perspective.
Further, this paper proposes an intelligent collaborative
security management model to minimize security risk. The
security challenges of the IoT for a smart home scenario are
encountered, anda comprehensiveIoTsecuritymanagement
for smart homes has been proposed.
What is IoT?
Internet of Things is the system to connect the physical
devices and operate or access through the internet. The
‘thing’ in IoT could be a person with a heart monitor with
built-in-sensors, i.e. objects that have been assigned an IP
address and have the ability to receive and transferdataover
a network without manual assistance or intervention. The
embedded technology in the objects helps them to interact
with internal states or the external environment, which in
turn affects the decisions taken..

3. SECURITY AND PRIVACY CHALLENGES
IoT provide novel and universal access to the devices that
make up everything from assembly lines, health and
wellness devices, and transportation systems to weather
sensors. Free access to that much data poses major security
and privacy challenges, including:
Fig -2: IoT Security challenges
Insufficient authentication/authorization: A huge
number of users and devices rely on weak and simple
passwords and authorizations. Many devices accept
passwords such as ABCD or 1234.
Lack of transport encryption: Most of the devices fail to
encrypt data that are being transferred, even when the
devices are using the Internet.
Insecure web/mobile interface: IoT-based solutions have
a web/mobile interface for device management or for
consumption of aggregated data. This web interfaceisfound
to be prone to the Open Web Application Security Project
(OWASP) Top 10 vulnerabilities, such as poor session
management, weak default credentials and cross-site
scripting vulnerabilities.
Default credentials: Most devices and sensors are
configured to use the default username/passwords.
Lack of secure code practices: Services and business logic
would be developed without adhering to secure coding
practices.
Privacy concerns: Devices used in the health care domain
receives at least one piece of personal information; the vast
majority of devices collect detailssuchasusernameanddate
of birth. However, the fact that many devices transmit
information across networks without encryptionposes even
more privacy risk. Privacy risk arises as the objects within
the IoT receive and integrate fragments of data that relate to
their service. For example, the regular purchase of different
food types may divulge the religion or health information of
the buyer.
4. MITIGATING SECURITY AND PRIVACY CHALLENGES
IoT products are manufactured only for security when
security is embedded at thetimeofproduction.Eachproduct
should undergo security parameters to detect
vulnerabilities.
Countermeasures, such as the following, can be taken to
address the security challenges:
Base device platform analysis: Weak platform
configuration might lead to compromises such as privilege
increases. Base device platform operating system and its
security properties, configurations and features should be
verified against the base-lined information security
requirements. Verification needs to be done to ensure that
any test interfaces are removed from the hardware.
Network traffic verification: Network traffic (wired or
wireless) should be analyzed for any in-disputable,
unencrypted or versatile data. There is a compromise
between performance and security when encryption is
recommended. Lightweight encryption algorithms can be
used to cater to performance requirements.
Verification of functional security requirements: To
validate the high-level functional security requirement. The
negative testing is important of software. IoT solutions can
uses the cloud services such asSoftwareasa Servicewhichis
based on identity management solutions for authorization
and authentication requirements.

Trust boundary review and fault injection: All trust
boundaries across the signal path should be reviewed and
subject to fault injection using negative test cases. The trust
boundaries can be verified using manual testing techniques.
Mostly Periodic penetration testing is suggested.
Side channel attack defense verification: If side channel
defenses are implemented, either in software or hardware,
they should be verified using continuous penetrationtesting
activities. Continuous penetration testing helps to minimize
advanced persistent threats (APTs) for IoT solutions.
Secure code reviews: Early secure code reviews lead to
early mitigation techniques. Sensitive and security impact
areas such as boot process, security enforcement and
encryption modules should go through secure codereviews.
The cost of fixing a security defect is greatly reduced when
the security vulnerability is discovered during the
development cycle.
End-to-end penetration test: End-to-end penetrationtests
should be conducted across the signal path to identify any
vulnerability in the web interface,mobileinterfaceandcloud
interface of the IoT solutions. The penetration testing give
the more security of the IoT solution for each components.
Security Assessment of an IoT Solution
A US-based software company developed a Secure Travel
product using IoT technology. The product provides real-
time data about the speed of vehicles,locationofthevehicles
and people traveling on the vehicles.
The technology components involved included:
 Sensors in the vehicles
 Gateways
 Services
 Web interface
 Mobile interface
Threat modeling using the Spoofing, Tampering,
Repudiation, Information disclosure,Denial ofservice(DoS),
Elevation of privilege (STRIDE) software approach was
conducted to identify the attack scenarios and formulate
mitigation plans for each of the components.
5. CONCLUSIONS
The Internet of Thing makes large development in
everyone’s everyday life. In the IoTs term, the short-range
mobile transceivers will be implanted in variety of daily
requirements. The connections between people and
communications of people will grow and between objectsto
objects at anytime, in any location. The efficiency of
information managementandcommunicationswill arise toa
new high level. The dynamic environmentofIoTsintroduces
unseen opportunities for communication,whicharegoingto
change the perception of computing and networking. The
privacy and security refer such an evolution should be
carefully considered to the promising technology. The
protection of data and privacy of users has beenidentified as
one of the key challenges in the IoT. In this paper is to
present the study of security and privacy issues in Internet
of Things (IoTs) and by present some challenges.
