Internet of Things (IOT)

IOT device security has long been a source of concern, which inevitably led to the acceptance of both minor and major threats. The majority of these attacks are the result of straightforward security issues, including the use of telnet services’ default passwords being retained. Below are the 6 major security problem in IOT devices.

Incorrect access control

Only the owner and the people they trust in their local vicinity should have access to the services provided by an IoT device. The security mechanism of a device frequently fails to adequately enforce this, though. IoT devices may have a high level of network trust to the point where no additional authentication or authorisation is needed. Every other computer or device linked to the same network is likewise trusted. When the gadget is online, this becomes a bigger issue since anybody in the globe might potentially use the capability it provides (Yu et al., 2022).

Outdated software

It is essential to publish the current version of software when vulnerabilities are found and fixed in order to provide protection. As a result, IoT devices must be deployed with current software that is free of known vulnerabilities and have the ability to be updated to fix any issues that are discovered later.

Lack of encryption

Even if data is encrypted, flaws could still exist if the encryption is incomplete or set up improperly. For instance, a device might not be able to confirm the legitimacy of the other party. Even when the connection is encrypted, a Man-in-the-Middle attacker can still intercept it.

Application vulnerabilities

An important first step in safeguarding IoT devices is admitting that software includes vulnerabilities. Device functionality that was not intended by the creators may be activated via software flaws. In some circumstances, this might lead to the hacker executing their own code on the system, making it feasible to harvest sensitive data or target other parties.

Insufficient privacy protection

Sensitive data is routinely stored on consumer electronics. The password for a wireless network is stored on devices connected to that network. Cameras can record audio and video of the house where they are installed. A serious privacy violation would occur if attackers were able to acquire this information.

IoT devices and associated services must handle sensitive data appropriately, securely, and only with the end user’s permission. This is true for both the distribution and storage of private data. The vendor is crucial in terms of privacy protection. In addition to an external attacker, the seller or a connected party may be in charge of a privacy violation (Haque et al., 2022).
