Factory IoT Network Security: Importance and Effective Security Methods 2023

I. Threats of Factory IoT System Security

Cyberinformation attacks are always the top concerns of businesses when conducting digital transformation. Most hazards come from one of the following:

1.1. Unencrypted data

An important threat to factory IoT systems is unencrypted data.

If information sent over the network is not encrypted, it can be stolen and read by attackers.

This could cause the disclosure of important information and lead to misuse of that information.

1.2. Financial information disclosure

Financial disclosure is a potential threat in the IoT system. If hackers are able to break into an IoT system, they can gather financial information, such as credit card information or banking information, and use it to commit fraud or gain unauthorized access to accounts. bank account.

1.3. Access to physical assets

IoT is the Internet of Things, which means it will allow remote control of a business's physical assets.

If an attacker is able to get into the system, they can take control of IoT devices and cause harm to the production environment, for example shutting down critical machines, causing problems or even causing damage. accident.

1.4. Weak passwords and identity verification

Weak passwords and weak identity verification are a potential threat in the IoT system.

If IoT devices are not protected with strong passwords or do not have a secure identity verification process, an attacker can easily break into the system and gain access and control of the devices.

1.5. Botnets and malicious IoT devices

Another notable threat is the proliferation of botnets and malicious IoT devices.

An attacker can break into the IoT system and take control of the devices to form a botnet.

The hackers then perform distributed attacks or send large amounts of network traffic to the targets in order to overload the system or interfere with the normal operation of the factory.

These threats all require corresponding attention and security measures to secure and protect IoT systems in factory environments.

II. Some ways to secure the factory IoT network safely

Because IoT is extremely necessary and indispensable if businesses want to go far and grow stronger. Therefore, it is extremely necessary to overcome and find measures to prevent threats. Some ways to keep the factory IoT system safe can be mentioned as:

2.1. Regularly update the system

Regularly updating the IoT system in the factory with the latest software version and security patches is an important measure to ensure safety.

These updates usually contain security enhancements, bug fixes, and fixes for vulnerabilities that have been discovered in the system.

Regular updates help prevent attacks from intruders by protecting your system from potentially harmful vulnerabilities.

In addition, the update also ensures that the IoT system can be compatible with the latest standards and protocols, providing higher security and improved attack resistance.

Therefore, performing regular updates is one of the important ways to keep the IoT system safe and secure in the factory.

2.2. Choose strong passwords

Using strong passwords for IoT devices in the factory is an important measure to protect the system. Here are some important rules when setting a password:

• Length: Make sure that the password is long enough to make it difficult to guess correctly. It is generally recommended to use a password that is at least 8 characters long.
• Character diversity: Use a combination of uppercase letters, lowercase letters, numbers, and special characters such as punctuation marks or special characters (@, #, $, etc.) to increase diversity. the form and difficulty of guessing the password.
• Avoid personal information: Limit the use of personal information such as name, date of birth, phone number or address in the password. This information can easily be correctly guessed by the intruder.
• Change it periodically: To be on the safe side, change your password periodically, recommended every 3-6 months or according to your organization's security policies.
• Do not use the same password: Limit the use of the same password for multiple IoT devices in the factory. If the password is revealed on one device, all other devices are also at risk.

By following the above guidelines and using strong passwords, plant IoT system managers can increase security and reduce the risk of attacks.

2.3. Be careful in using wifi

Taking care when using Wi-Fi is an important factor in protecting IoT systems. Here are the measures to take to ensure safety when using Wi-Fi:

• Use a Wi-Fi security protocol: Make sure that the Wi-Fi network is configured to use a Wifi security protocol such as WPA2 (Wi-Fi Protected Access 2) or WPA3. These protocols provide a higher level of security than older protocols like WEP (Wired Equivalent Privacy).
• Strong Password: Set a long and complex Wifi network password. Use a combination of uppercase letters, lowercase letters, numbers, and special characters. Avoid using easy-to-guess personal information and weak passwords.
• Turn off the WPS feature: WPS is a feature that allows to quickly connect devices to a Wifi network using a PIN code or push button. However, this feature may have security holes and is vulnerable to attacks. Therefore, it is recommended to disable the WPS feature in the Wi-Fi network settings.
• Software Update: Make sure that the Wi-Fi router and IoT device are both updated with the latest software from the manufacturer. Updates often include security patches and performance improvements to mitigate security vulnerabilities.
• Guest network: If available, use a guest network for guests or IoT devices. This helps isolate network traffic and reduces the potential for untrusted devices to impact the main system.
• Access control: Use the access control features on the Wifi router to limit connected devices and authenticate users when accessing the Wifi network.
• Monitor network traffic: Use network monitoring tools to monitor network traffic and detect possible unusual or intrusive activities.

By taking precautions when using Wi-Fi, plant IoT system managers can increase security and prevent unauthorized access to the network.
