Main IoT Security Challenges And Threats

IT Biz Today Staff

The main threat to human beings in this decade will be cyberwar, not the physical battles involving multiple states or nations. Cyberwar is something that may damage the privacy of people, the conversations between them, their photos, moments, and all the things that encompass them.

Technology is something that has both negative and positive effects. Technology doesn’t just have benefits, but it also comes with never-seen-before threats. For people to work harmoniously with it, they must face and deal with the likely threats that come with it. Just disregarding the threats is no longer an option.

The Things That Are Likely To Damage Internet Of Things, And IoT Challenges

Any internet-connected device is exposed to threats. Some businesses are aware that they are hacked, but others do not even know the occurrence of hacking. The latter situation is more dangerous, and it helps to explain the actuality that businesses are always at risk of cyber threats. What matters the most is which business the least exposed to threats is.

Without addressing and confronting the worse things in the cyber world, it is not possible to take measures that counteract the threats. A purpose supports all threats, including website-related threats and the ones associated with the internet of things. Every single threat may differ according to the target of the cyber intruder. The target may be any or a combination of the following.

  • People utilize and operate the internet of things devices, so one might wish to have access to their information without asking for it.
  • By spying on these devices, he or she might wish to obtain confidential details.
  • Internet of things devices operate on fewer computing resources and low power, so it is not possible to have complicated security protocols for these devices. Therefore, it is easy for an intruder to access the devices.


The vulnerability of an internet-connected device is the easily identifiable and most fundamental threat to it. IoT solution providers address the issue before they think about the basic software on which other programs depend.

There are two possible forms of vulnerability: software and hardware. The former vulnerability can be either a software line of code (LOC) that has a backdoor file or a badly written algorithm. The file will offer backdoor access to an intruder, who seeks precisely this vulnerability.

Easy Exposure

It is among the most basic problems that the internet of things sector faces. An unattended device or a device that is vulnerable to trouble is one that tempts malicious parties to target it. Usually, any person can access the internet of things devices. A person can get control of an IoT device and connect it to a different device that contains dangerous data or attempt to draw out cryptographic secrets from it. Thereby, they will be able to modify the programming of it or even replace it with the malicious device they have full control of.


There are two forms of threats: natural and human. A threat that emerges from a natural calamity can considerably damage the internet of things based devices. In this situation, people backup data on the devices or make a plan B to protect the data. That said, it is not possible to restore the devices in the event of these having any physical damage.

Today’s IoT devices have advanced features, such as being impervious to water. It will take much time for IoT-related companies to create devices that can withstand the effect of an earthquake or fire.

On the other hand, people do anything possible to control the threats that others pose to the said devices. The human threats are generally in the form of the attacks. These threats are identifiable in the following forms.

  • Reconnaissance Attack. In this attack, cracking methods and malicious programs are utilized to spy on the user for access to confidential information or destroying active systems.
  • Tracking. All the moves of the user are traceable or trackable by their internet of things device’s unique identification number. Monitoring a user will reveal precisely where they are located when they want to stay anonymous.
  • Brute Force Attack. An intruder tries to deduce the password of a user through an automated program that makes countless attempts up to the time the correct credential gives the access.
  • Controlled Attack. It is doable through denial of service, virus, or Trojan. In this kind of situation, an intruder creates a certain virus program to work in such a way as to sabotage the network host. Developers and programmers must be watchful when they work on present IoT devices because today’s hackers possess powerful tools to initiate cyber attacks from anywhere in the world.
