The Internet of Things (IoT) technology is used in homes as well as in industries to make them smart. It is predicted that in coming years there will an immense increase in the number of IoT devices. They will be in billions that will make a revolution in the industry of connected devices. But the increasing IoT devices have also made security a great challenge for people. The hackers find loose ways to attack the devices. This is because the traditional devices cannot detect these attacks that create a serious threat for all the connected devices. If this issue remains unattended then proper secure IoT devices will only be a dream.

Don't delay your career growth, kickstart your career by enrolling in this IoT Online Course with 360DigiTMG.

Attacks come in different shapes and methods, so it is necessary to take precautionary measures. In this article, different IoT attacks will be addressed and you will also get to know that to protect the customers from these attacks. So let's take a look.

The Common IoT Attacks:

The attackers have found different ways to attack the system. The experts have analyzed the IoT devices completely to understand the risks and vulnerabilities. The analysis shows some common types of IoT attacks that are seen on most devices. Let's discuss them one by one to develop a complete understanding of IoT device's risks and threats.

  • Brute Force Password Attacks

    Most of the users do not change the passwords of their IoT devices and keep on using these devices with default passwords. Some other users change the password of devices, but they create a weak password that can be easily guessed by hackers.

    The attacks that happen due to weak passwords are known as brute force password attacks. In this attack, the cybercriminals attack the device by creating a brute password. They gain access to the devices and can alter or misuse the data of the users. This has created a great alarm for the security of IoT devices.

    The solution to this issue is that the administration restricts the users and manufacturers to create a password that cannot be guessed by malicious persons. The password policy must contain some kind of identity check to make sure that the person who is accessing the system is valid and authorized. In this way, the brute force password attacks can be deferred.

  • Denial of Service (DOS) Attacks

    The denial-of-service attacks are increasing day by day. And has been revealed that in 2017 the DOS attacks are increased by 90 percent and all are the gifts of IoT devices. This means that these are the IoT devices that have created a great threat for the connected devices.

    In these attacks, the attackers hack the system, and the system denies performing any tasks for the users. The system loses its connection to the Internet. All this happens due to DOS attacks that put the system offline and steal the personal and sensitive information of the users.

    Being a IoT is just a step away. Check out the Internet of Things Training in Bangalore at 360DigiTMG and get certified today.

    IoT devices are not managed properly that is why an unknown device may enter into the network by claiming that it is an identified device. This can put the entire network at risk. The solution to this issue is that the manufacturers must introduce a way for authenticating devices.

  • Privilege Escalation Attacks

    In these attacks, the attackers focus on the flaws in the design of the IoT and operating system, etc. When they get the flaws means they found a way to attack the devices, they get honored access to the devices and start exploiting these devices.

    The attackers use different methods to find the information that is usually hidden from the users of IoT devices or even the IoT applications. To reduce or eliminate the risk of these attacks the manufactures must make an IoT device that has no security flaws. The authorities have to take action. Otherwise, the privacy of the users will be violated seriously.

  • Firmware Hijacking Attacks

    The users who update their IoT devices do not make a sense that are they using the right source for updating their device or not. They keep on downloading the updates from malicious sources that include viruses or worms to attack the system.

    When the users attempt to update the device, it takes the necessary information from the users and then uses this information to gain an access to the device. These attacks are common because most of the consumers do not know the proper channel to download updates and many of them are not highly educated.

    In this way, the malicious software becomes a reason for firmware hijacking attacks. The solution is that the administration must educate the users and make them aware of the right sources.

  • Physical Mitigation

    When a device is installed in a location where it is not monitored regularly or even remains unseen, the attackers get a golden chance to attack these devices.They have an idea that they will not be detected because the device is not monitored.

    In this way, they gain access to the different controls of the network via this device and can bypass different security measures. This device will be a ladder for the attackers to reach the sensitive information of the system.

    To discourage this attack, it is necessary to monitor all the devices anywhere and their activity must be checked regularly. And if there is any security fluctuation found then it can be cured before getting a severe issue.

  • Snooping Attacks

    The attackers are always in search of the flaws in the network so that they can continue their illegal and malicious activities. When the cybercriminals found that there is a poor connection between server and IoT devices then the attacker is ready to interrupt the network communication and can steal the important information that is transmitted by the IoT devices. To ensure no such attacks it is necessary to build a strong connection between IoT devices and the server. The attackers will not found flaws and the data will remain protected.

Wrapping Up

Many more IoT attacks are causing a threat to the success of IoT devices. It is necessary to act against these attacks and introduce a different method to apply a security check on the devices. In this way, the devices will be out of the reach of the attackers and be safe.
