The billions of physical objects connected to the internet and collecting and exchanging data collectively are referred to as the Internet of Things (IoT). Anything can be made a part of the IoT as technology develops further.
Even though we may now accomplish things that were formerly thought impossible, digitizing everything has some drawbacks. Data becomes increasingly appealing to thieves as more gadgets are connected to the internet (through ransomware, for example). IoT device security is essential to avoid being a victim of cybercrime.
What Makes IoT Security So Crucial?
Before we proceed further, I suggest you go through the guide on creating IoT software. Numerous instances of IoT device hacking have already occurred due to hackers finding and exploiting IoT security flaws. Even the equipment attached to industrial robots at certain organizations has been compromised.
The rationale is that hackers have access to production logic, control-loop parameters, the condition of the robot, and many other things. Researchers decided to show how much harm a hacked robot is genuinely capable of. They were able to program the robotic arm to harm the goods it was producing for millions of dollars after discovering flaws in its system.
Criminals on the internet won’t stop until they have compromised medical equipment. The 2017 NHS WannaCry ransomware outbreak illustrated this, which impacted computers, MRI scanners, operating room equipment, and numerous endangered lives. IoT device security is essential because of this.
How to Strengthen IoT Security?
IoT security wasn’t taken seriously until recently when numerous hacking incidents had disastrous results. Many IoT security solutions are now being implemented to close security gaps and prevent security breaches at the device level, preventing the issue before it has a chance to cause havoc.
This is because IoT security weaknesses are like a welcome sign for hackers. Here are some IoT security best practices that companies may use to safeguard their equipment.
Modify the Default Passwords Regularly
Even though this first step in enhancing IoT security may seem rather simple, some companies fail to update the passwords they were first provided. After being updated, passwords need to be changed regularly.
To ensure accounts are properly protected, a firm can even implement forced password changes after a predetermined period. Employees won’t end up writing down passwords because of the use of a password vault to protect them. This blocks one entry point hackers might use to access the network and steal sensitive data.
Verify the Software’s Security
IoT-connected devices can be protected by incorporating active security controls into their software. One strategy to defend devices from potential assaults is to provide security features like password protection for software access.
Additionally, it’s crucial to prevent IoT devices from opening network connections on their own. If programs aren’t restricted in usage or prevented inside firewalls, sensitive data may get leaked.
To ensure there are no hidden risks or security holes, any devices and software placed on them must be reviewed regularly. Keeping software updated in the struggle against IoT security vulnerabilities is crucial.
