Abstract- Development in technology has allowed us to consider whatever we could do, before the age of
aviation nobody would have imagined they could fly in the air, but a generation-wide development in
innovation and technology has empowered us for having the better future.
“The smart home is among the best examples we can use for claiming that it makes the home life easier
because it helps us to control the devices in the home remotely so that there will be no worries about the
home, and with the aid of IoT (Internet of Things) it is possible. It enables us to look at the home from
anywhere in the world.
But the things that need for being taken care of are protection, nowadays this is very easy to break the
privacy and security of someone, so that the only things that need to be taken care of are the security and
the countermeasures that make our lives very easy.
Therefore in this paper we are going to examine the risks and countermeasures and problems in the smart
home system today. Next we will also explore the architectures of smart homes.
Keywords—Internet-of-Things (IoT), Smart Home, Attacks, Threats, Countermeasures, Security, Privacy,

I. INTRODUCTION
As the title suggests, IoT proposes that this is the Internet thing that can be done with the help of the
Internet. Means whatever stuff we can manage with the help of the internet is known as the internet-of-
things, any appliance or device associated with the IoT need in being connected to the internet across
their lives so that anyone become able easily access the smart appliances and devices.

Advancing Internet technology are rising the boundaries of the Internet connectivity, being cheap and
ubiquitous even in developing nations or the rural regions. The capability of the computer storage and
distribution increases significantly as its dimensions become smaller that is highly appropriate for
different types of sensors. Real items are also increasingly fitted with the RFID (Radio-Frequency
Identification) tags, NFC (Near Field Communications) tags or another digital bar codes, which can be
checked with the smart devices such as laptops, smartphones and the other small devices compatible with
the NFC or RFID readers. This combination links the physical environment via the smartphone or tablet
to cyberspace, thus expanding Internet capabilities towards the next phase of the Internet could be called
IoT. [1]
Smart Connect home, Home automation systems are the very important and promising field, because they
save money, energy, time and provide protection and convenience. In addition, smart home systems will
help people and the aged with disabilities and needs. IoT-based HAS (Home Automation System) is that
day by day across the world, especially in recent years as things link and communicate over the Internet.
Smart home systems offer protection and comfort to its owners. In fact, these devices are environmentally
friendly that is among the most significant concerns in the world today. Several scientists have been using
different sensors for designing and implementing the smart homes based on the various technologies. The
smart home system was installed in the IoT, based on the 5G integrated system and the Zigbee
techniques. [2]

Smart homes are associated with the embedded technological devices, which provides the central
regulated service or remote service and the functionalities. For the automation in the homes, multimedia,
telecommunication and health, the technical infrastructure focused on the technology integration. The
idea of the smart homes has the huge growth, which is constrained by the understanding, implementation
and knowledge heterogeneity. In multiple fields of the Ontology of computer science, the smart home
technology has received the recognition for sharing and reusing the knowledge. Numbers of engineers
and scientists are incorporating with the programs of ontology and producing the great outcomes. [7]

II. SMART HOME ARCHITECTURE

Fig. 3 Underlying Architecture of Smart Home [6]
In developing the home into the smart home network, the smart home system has several components that
will help.
The components are
 Communication Protocols
 Sensor Interface
 Microcontroller
 Smartphone
 Application and Business Layer
 Network Interface
 Sensors
 Appliances
