Smart manufacturing has now risen to become the new norm for the manufacturing industry in 2025. The Internet of Things (IoT), machine learning, and artificial intelligence (AI) have made factories faster, more adaptable, and more efficient than ever in the past. These "smart factories" can now use data to enhance performance, provide real-time problem-solving capabilities, and react rapidly to market demands. However, with the increase of technology, the risks are even higher. Factories are more vulnerable to cyberattacks as they become more interconnected. Protecting these modern systems from hackers and digital threats is now a top priority for the manufacturing industry.

❖ Why Are Smart Factories at Risk?

Networks of machines, sensors, software, and data are the foundation of smart factories. Although this configuration increases both output and quality, it also gives hackers easier access to the company's important data, such as future product designs, customer information, and production secrets. Those malicious acts could be harmful to the company and cause significant financial damages as a result of the theft or exposure of this information.

Indeed, research indicates that industry is currently the target of 25% of worldwide cyberattacks. Stronger cybersecurity is therefore more crucial than ever.

❖ Challenges in Securing OT Systems

As many factories had been in the industry for a long time, they still used the old machines and the ancient systems to run their company. These are part of what’s called operational technology (OT): the tools and systems that control things like production lines, robots, and equipment. This blend of modern and ancient technologies generates security issues that need to be handled with caution.

Here are some of the major obstacles:

1. Outdated Systems (Legacy Technology)

Many factory machines work with older systems that were never built with cybersecurity in mind. These systems might use older protocols, lack encryption, or be harder to update. Often, cybersecurity updates have simply not been a priority, leaving them open to attacks.

2. IT vs. OT

● IT (Information Technology) has a focus on keeping the data safe, private, and accurate.

● OT (Operational Technology) focuses on keeping machines running.

As IT (information technology) and OT (operational technology) systems, they often follow different rules and standards when it comes to cybersecurity.

For example, IT might use global frameworks like NIST to guide their security, while OT systems often stick to the industry standards that vary from one sector to another. This makes it harder to set up a unified security strategy that works for both sides of the factory. Which can result in cyberattackers finding weak spots.

3. Fewer Individuals With The Proper Training

The absence of cybersecurity specialists in the field who are knowledgeable about both IT and OT systems in the company is another significant issue.

The majority of OT specialists lack cybersecurity training, and the majority of IT professionals lack knowledge of factory machinery. Building a solid team that can defend the entire system is challenging due to this knowledge gap. Although it's still uncommon and difficult to obtain, cross-training employees or employing individuals with hybrid talents is crucial.

❖ The Importance Of Data Protection Strategies In Smart Factories

One of the most precious resources of a company is data. Data is present in every part of smart manufacturing, from simple machines to cloud-based platforms used for planning, logistics, or other uses. Therefore, this important data being in the hands of cyberattackers could cause major damage to the company. This is the reason why choosing a great strategy is important. Here are some points that can be useful:

● Data encryption: Encrypting the data can prevent stolen information from being read.

● Stronger authentication system: Making use of multifactor authentication and strong passwords

● Conduct risk assessment: Performing routine backups, in case systems are compromised, can help prevent potential problems from becoming cybersecurity risks. Keeping an eye out for any odd activity that would indicate a breach

● Set Up Of Stricter Regulation

The governments and other regulatory entities are slowly introducing new laws and requirements to help protect the industries from rising cyber threats. Furthermore, those who do not meet the security standard could face lawsuits, fines, or even be forced to shut down their business.

To stay under compliance, they must:

● Understand and follow cybersecurity laws in their region.

● Document their security measures and updates.

● Train employees to follow safe practices.

● Review and improve their systems regularly.

Cybersecurity is now necessary, not optional. The secrets to remaining secure and competitive in 2025 and beyond are data protection, system security, and adherence to regulations.

Manufacturers must exchange best practices, learn from experts, and keep up with emerging tools and dangers if they want to stay ahead.
