A smart home environment is meant to be a small physical world consisting of different devices, including sensors, actuators, monitors, and computational elements that interact and exchange information with users to provide them with automated, custom and secured services. These types of environments are designed to make life better and safer through information processing, automation and personal services.
The potential of smart home environments is huge; For example, smart homes are primarily designed for elderly people because such homes are able to uncover, process and forward their important health information and communicate the data through integrated devices and networks for protection.
Further, smart homes can help old-law people live an independent and better life.
The need for such automated and digital environments increases to provide better facilities and improve the quality of life. The best way to improve quality of life is to create a home environment in a smart home environment, making it a more comfortable place to live.
It also aims to satisfy the perception of individuals from all environments by replacing dangerous work, physical labor and repetitive tasks with automated agents. It has become possible with the emergence of flexible portable character sensors and placement codes that can track people's health status.
As the more personal information is collected and communicated on the wireless network, privacy issues are more pronounced that must exploit the full benefits of smart home environments. Security generally deals with cryptographic techniques used to secure communication channels by ensuring message integrity, confidentiality, authenticity, while privacy examines the issues associated with trust and risk associated with collection, storage, distribution and association of personal data.
In a typical smart home environment, things that are formed by the integration of these electronic elements are expected to perceive, process and transfer data collected from the mix of different devices, users and computers connected to the environment to respond to personal services to users. Different sensors can be placed in different places like offices, apartments and homes to collect user information and medical data.
The network is responsible for collecting, distributing and processing large amounts of private data with other networks, domains or systems (such as the Internet), which will ultimately lead to increasing security, privacy, and reliability concerns across the network. Before moving on, let's understand what is the Internet of things?
What is the Internet of things?
Internet stuff (IoT) is a network of physical objects like machines, vehicles, home appliances and more. The technology uses sensors and APIs to connect and exchange data over the Internet.
Today, it appeared as a reliable alternative that enhances the quality of life in smart homes by offering different automated, interactive and comfortable services. The IoT-based solutions allow people and things to be connected at any time and anywhere using any network and service.

They are "Material Objects Related to Material Objects on the Internet". To build IoT-based applications, a wide range of technologies are involved. For example, RFID for location and device identification, enhanced personal and wide area networking protocols, web technologies, etc.
These technologies help build a virtual world of things on top of the physical world where things go through Machine-to-Machine (M2M) communicate with each other through human-to-machine interactions, provide information to people or take measures on human inputs or act as passive devices to provide data to intelligent devices.
But what are the security issues for the smart home environment and how the Internet in things can help develop a safe and secure, smart home environment?
Smart Home Environment Vulnerabilities
People living in the smart home environment are increasingly relying on wireless network information that monitors, collects and analyzes important data about them, their vital signs, places, movements, use of devices and use, and send them to carers or other approved agents for decision making.
Such private and sensitive data generated by the interaction between different intelligent devices and sensors is communicated to the outside world via other existing network technologies, and possibly Interment for further processing, analysis and database storage. The integration of such a wide range of devices, networks and different technologies, along with the Internet, provides no room for neglecting the latest security issues, architectures, protection and defense mechanisms.
In addition, sensor units are distributed or placed inaccessible areas to increase security issues. The dynamic nature of sensor networks, ie node and link errors combined with critical data placement, placement and context awareness and coordination of heterogeneous devices and sensors, adds security challenges. The traditional security threats, attacks and defense mechanisms that exist for wired and other computer networks and communications networks, and even for the Internet, also apply to wireless networks.
To provide complete security, the security network must be integrated into all the nodes of the System otherwise an insecure component of the network may be an attack point and may make the entire system vulnerable. Therefore, security must be successful in all aspects of the design of the IoT application that requires a high level of security. It is obvious that the network without any protection mechanism may suffer from attacks or malfunctions and may interfere with the services offered by the network.
When it comes to talking about the vulnerabilities in the smart home environment, the following are some important security requirements that are measured to ensure security.
Confidentiality: It refers to preventing disclosure of information to unauthorized persons, parties or systems. The Service's Internet Confidentiality secures the network by preventing unauthorized parties from accessing data generated, such as domain-specific information, such as user identity, posts, and other related information sent to the network. In other words, an eavesdropper should not be able to extract the contents of a confidential message.
Integrity: It refers to preventing forgery, modification of data transmitted in the network by unauthorized persons or systems. More specifically, in the automation system, this applies to information such as sensor values, or control commands. This goal includes protection against information change via messaging, message response and message delay on the network. Violation of integrity may interfere with security issues, that is, modified or fake data may malfunction and damage control systems and facilities such as communication and security systems, lighting, heating and hydro systems.
Freshness: It means data integrity and key freshness. It is concerned whether the data produced or measured in the system is recent or not. This is very important in the context of the smart home environment, since sensors often understand and transmit time-critical data such as some blood pressure and heart rate at certain times more important than other times and should be handled in real time to ensure life security.
Availability: It indicates that unauthorized persons or systems can not deny access system resources to authorized users. For automation systems, this refers to all IT elements in the home environment, including control, security, tools and entertainment systems, as well as the communication systems between these elements and the outside world. It simply means that the availability of services ensures that only authorized entities can access data, services, and other available resources when prompted.
Authenticity: It is related to restricting the identity of a system user or device and mapping of This Identity to a system-internal principal (such as a valid user account) that this user is known for the system. In other words, authentication between legitimate and illegitimate users in a system separates
