Does Industrial 4G Router Require Frequent Password Changes?

In the wave of digital transformation, traditional industries are gradually integrating into the vast world of Industrial Internet of Things (IIoT). As a key infrastructure in this transformation, industrial 4G Router carries the heavy responsibility of data transmission and device interconnection. However, on the road to ensuring network security and stability, a seemingly simple but often overlooked question has surfaced: does Industrial 4G Router need frequent password changes?

1.Conventional knowledge of password replacement
In consumer grade network environments, users are often advised to regularly change their passwords to enhance security. This approach aims to reduce the risk of accounts being illegally hacked, as prolonged use of the same password may increase the likelihood of being cracked. However, whether this conventional understanding is equally applicable in the field of industrial Internet of Things is a question worth exploring in depth.

2. The particularity of Industrial 4G Router

Industrial 4G Router is significantly different from traditional consumer-grade routers in terms of design, functionality and operating environment. They are usually deployed in more complex and harsh industrial environments, undertaking heavier data transmission tasks. In addition,industrial4Grouters often have higher security and stability requirements to cope with harsh conditions in industrial production.

3. Analysis of the Necessity of Password Replacement

Security considerations

For Industrial 4G Router, security is one of the primary considerations. However, frequent password changes are not always the best way to improve security. In the industrial Internet of Things environment, the complexity and confidentiality of passwords are far more important than the frequency of replacement. A strong password consists of a combination of uppercase and lowercase letters, numbers, and special characters, and is long enough to significantly reduce the risk of being cracked.

Industrial access permissions for 4G routers should be strictly controlled and only authorized to necessary maintenance and management personnel. By implementing security measures such as multi factor authentication and access control list (ACL), the security of routers can be further enhanced.

Stability and maintainability

The stable operation of Industrial 4G Router is crucial for industrial production. Frequent password changes may increase the risk of human error, such as input errors causing devices to be inaccessible or configuration errors affecting network performance. In addition, for Industrial 4G Router that requires remote maintenance, frequent password changes may also increase the difficulty and cost of maintenance.

Therefore, while ensuring password security,  The password change frequency of Industrial 4G Router should be flexibly adjusted according to the actual situation. It is recommended to regularly review password policies, such as every six months or every year, and make adjustments and optimizations as needed.

4. Best practices

Adopt a strong password strategy

Ensure that the password for Industrial 4G Router is sufficiently complex and difficult to guess. It is recommended to use password management tools to generate and store strong passwords, and regularly review password lists to ensure their security.

Implement multi factor authentication

In addition to passwords, implementing multi factor authentication such as SMS verification codes, hardware tokens, etc. can also be considered to enhance the security of access control.

Regular audits and monitoring

Regularly audit and monitor the security configuration of Industrial 4G Router to detect and fix potential security vulnerabilities and threats in a timely manner.

Flexibly adjust password change strategies

Flexibly adjust password replacement strategies based on the actual situation of the network environment and security requirements. Minimize unnecessary replacement operations while ensuring safety to reduce maintenance costs and risks.

Whether Industrial 4G routers need to frequently change passwords is not a general issue. On the premise of ensuring network security and stability, password replacement strategies should be flexibly adjusted according to actual situations. In the future, we should pay more attention to the complexity and confidentiality of passwords, the effectiveness of access control, and the importance of regular auditing and monitoring. Only in this way can we provide more solid and reliable network support for traditional industries on the path of digital transformation.
