IoT Security Challenges and Issues | Solutions for Securing IoT Devices

The Internet of Things (IoT) is a network of objects, machines, and devices that can send data over a network without any help from a person. An IoT system could be a car with sensors built in that tell the driver when the tire pressure is low. It can be a biochip transponder that is put in an animal on a farm.

It can also be an implanted heart monitor or anything else that uses an internet protocol (IP) address to send data over a network. IoT is used by businesses to improve customer service, make better decisions, increase the value of the business, and run more efficiently. The Internet of Things (IoT) is growing at a very fast rate.

By 2025, there could be as many as 26 billion devices connected to it. IoT technology has a lot of benefits for the transportation, healthcare, manufacturing, business, and consumer sectors. But if problems with IoT security aren’t fixed, as more devices are added, connected networks will be more vulnerable to cyberattacks. Below are the IoT risks and challenges as well as solutions to prevent your business from them.

IoT Security Challenges And Solutions In 2022

IoT puts a lot of weight on the fact that these devices need to have reliable security measures. Today, we will talk about the biggest IoT security problems that are putting these systems all over the world at risk. And how to solve them with some suitable methods or approaches.

IoT Cybersecurity Issues And Challenges

We will walk you through the 5 most critical IoT security issues and challenges you or your enterprise may face.

1. Weak Passwords

Even though it sounds silly, many people in charge of installing IoT devices forget to change the default logins and passwords. Many people use factory default passwords, which makes their IoT devices and networks very vulnerable. Weak or default passwords are often at the top of the list of problems with IoT security. Hackers use preset passwords and brute force to figure out the passwords and get into the IoT device, which gives them access to all the other devices on the network.

2. Poor Device Management

Even though huge networks of IoT devices are being built, security compatibility between IoT devices is not getting the attention it deserves. Hundreds to thousands of IoT devices can be found on a single network in places like retail, healthcare, mining, and shipping.

These devices are made by different companies, each of which has its security and firmware needs. Legacy devices often make their way into these complex networks and become the main cause of security problems in the IoT. Hackers look for these devices so they can break into the network and attack it.

3. Outdated IoT Software

Legacy operating systems, corrupted updates, insecure update deployment, and old firmware can all put the whole network at risk. This opens the door to a lot of the challenges of securing IoT devices, which are often followed by attacks on a large scale.

Many businesses that used third-party software and hardware in their supply chains paid a high price. Unsafe software components and libraries that are no longer used can put the device and the network it is connected to at risk. On top of that, there aren’t regular security patches or firmware updates, which makes things even worse.

4. Compromise In Privacy

Data is the new oil, and it pays to have access to it. Hackers constantly attack networks to try to find holes in them, just like a bad neighbour might fire shells across the border. When data is poorly managed and has little or no security, it attracts hackers and groups who use it to their advantage by making it public, asking for a ransom, or even stealing it.

IoT Ransomware attacks are becoming more and more common as IoT security issues. Recent research shows that more than 95% of the data that flows between IoT devices is not secure. This leaves huge amounts of data out in the open, where a rogue intruder could steal them.

5. Insecure Authorization And Authentication

The most important part of an enterprise’s IoT network is how devices are authorized and verified. Since every device could be an entry point, it is important to make sure that all devices that connect to the network are authorized and verified according to policies. Recent research has shown that about 20% of IoT devices on such networks are not supposed to be there. Even tech giants like Tesla have had to deal with the problem of unauthenticated devices getting into business networks. In terms of security breaches, this is a very common cybersecurity challenge in IoT in the healthcare sector. There are more fake devices on the market, and their operating systems are often changed in a way that makes them easier to hack.

Solutions To Prevent Or Overcome Such Problems

Below are the solutions or preventions that you should implement to keep your IoT devices safe from hackers and breaches.

1. Weak Passwords

Change the default password on your IoT device as soon as you get it, even before you connect it to the internet. Try to use a strong, complicated password and stay away from simple words. Hackers use software that can decrypt hash keys and hash keys of common passwords. It is strongly suggested that only one IP address be used to log in. This makes it very hard for people in different places to connect.

2. Poor Device Management

To overcome security and privacy challenges in the industrial internet of things, enterprises should hire an Operation Technology Manager (OT Manager) who knows how to manage networks and is good at it. Legacy devices should be taken off the network, or their security firmware should be updated to be on par with other devices. Businesses should micromanage the network by dividing it into different parts. All IoT devices and their networks should go through constant and regular security checks for security holes, firmware updates, alerts, and reports.

3. Outdated IoT Software

Any software or hardware from a third party that will be part of the supply chain should be carefully checked by security experts. Frequent updates and secure update mechanisms should always be done through channels that are both safe and encrypted. Before putting updates on the IoT device network, they should be checked for both their integrity and where they came from. Banks can deal with IoT security challenges in the finance industry by changing the devices’ operating systems safely.

4. Compromise In Privacy

Cryptography is the best way for users to keep their data private, so they can use it to protect their data. Large companies should use strong data encryption (like 256-Bit encryption) to protect the privacy and confidentiality of their data. Federated Machine Learning (FML) can help you and your company deal with or avoid these kinds of problems.

5. Insecure Authorization And Authentication

• Enable two-factor authentication where your account will send you a verification message on your phone via message or mail to confirm.
• Companies can install additional biometric authentication to enhance the security in their server rooms.
• Always use strong passwords containing special characters, and numbers, and should be above 8 characters.
• Privileged Access Management (PAM) is essential to bring down the number of IoT security threats and challenges.

IoT Security Challenges And Solutions

IoT devices that aren’t secure put users, systems, devices, and networks at risk. But IoT security isn’t just a matter of how a company sets things up. Users and admins should work together to create a security culture in order to keep IoT safe.

For users, this means doing things like blocking remote access that isn’t needed and changing the security passwords that come with the system. By reading the IoT security threats and solutions in this guide, you should be prepared for the future. Share your thoughts on this post in the comments section below.
