The manufacturing industry has undergone a digital transformation in recent years, leading to increased productivity and efficiency. However, this has also created new cybersecurity challenges. Manufacturers, once primarily concerned with physical security, must now tackle a growing number of cyber threats that can disrupt operations, compromise sensitive data, and cost millions of dollars. Fortunately, there are some strategies and advanced technology solutions that companies can implement to address these challenges and protect themselves from malicious actors.
1. Legacy Systems
Many manufacturers still rely on outdated systems that were not designed with modern cyber threats in mind. These legacy systems often lack important security features, making them easy targets for cybercriminals.
Solutions:
Conduct a comprehensive audit of all legacy systems, and prioritize updating or replacing them with more secure alternatives. If upgrades are not feasible, segment the network to isolate vulnerable systems and minimize risk.
2. Industrial Internet of Things (IIoT) Vulnerabilities
Increased use of IIoT devices in manufacturing has changed the way factories operate. But these devices often lack robust security features, and can serve as entry points for threat actors. Once compromised, IIoT devices can be exploited to disrupt operations, steal data, or launch further attacks.
Solutions:
Manufacturers should segment IIoT devices from the rest of the corporate network, so that they cannot be used to gain entry to other systems. Data must be encrypted at rest and in transit, so that even if it is stolen, it cannot be used. Maintaining an inventory of all connected devices can help companies identify vulnerabilities.
3. Ransomware Attacks
Ransomware is a growing threat in the manufacturing industry. During these attacks, cybercriminals encrypt a business’ critical data and demand a ransom to restore access. In some cases they will now use double and triple extortion tactics, threatening to release or sell data. Ransomware can shut down entire production lines, resulting in massive financial losses.
Solutions:
To combat ransomware, manufacturers will need a multi-layered defense strategy that includes regular data backups, network segmentation, advanced technology solutions designed to detect and block threats, and employee training on how to recognize common entry points such as phishing attacks. Endpoint protection and intrusion detection systems (IDS) can help detect and block ransomware attacks before they spread.
4. Supply Chain Vulnerabilities
Manufacturers are often dependent on a vast network of suppliers and partners, making supply chain security a critical concern. An attack on a supplier can potentially compromise a manufacturer’s own systems and data.
Solutions:
Companies should implement a vendor risk management program . This involves assessing the cybersecurity practices of all third-party vendors and suppliers, and requiring them to meet specific standards. Access controls should be used to limit third-party access to sensitive data.
5. Lack of Cybersecurity Awareness
Employees in the manufacturing industry may not be familiar with cyber threats. Without proper training, employees may unwittingly become attack vectors by falling victim to phishing scams, mishandling data, or using weak passwords.
Solutions:
Develop a comprehensive cybersecurity training program tailored towards the manufacturing industry. Training should be ongoing, and include simulations to identify gaps in employee knowledge. Take steps to develop a security-first culture within the company.
6. Intellectual Property (IP) Theft
Manufacturers are often targeted for their valuable IP, including proprietary designs, formulas, and processes. Threat actors or competitors may seek to steal this information, putting a company’s competitive advantage at risk.
Solutions:
Strong access controls and encryption will protect IP by ensuring that only authorized personnel can access sensitive information. Data loss prevention (DLP) tools can help monitor the movement of sensitive data, and regular security audits can identify potential vulnerabilities.
7. Operational Technology (OT) and IT Convergence
The integration of OT and IT in modern factories enables more efficient operations and better sharing, but it also creates risk. OT systems – once isolated – are now exposed to cyber threats targeting traditional IT networks.
Solutions:
To secure OT systems, manufacturers should adopt a zero trust model, which assumes that any access request could be a potential threat. OT systems should also be continuously monitored for any signs of abnormal activity. Regular collaboration between IT and OT systems is essential, for ensuring security across both domains.
