Top Cybersecurity Challenges in Manufacturing Software and How AI Can Help

Introduction

Manufacturing has become increasingly digital.

Modern factories no longer depend only on physical machines and manual processes. Manufacturing organizations now rely on enterprise applications, industrial control systems, connected machines, IoT devices, cloud platforms, APIs, production management software, ERP systems, and operational technology (OT) environments to manage critical operations.

This digital transformation has created significant opportunities for manufacturers. Companies can monitor equipment in real time, automate production processes, collect operational data, optimize supply chains, and improve productivity.

A vulnerability in manufacturing software can potentially affect production operations, expose sensitive business information, disrupt supply chains, or provide attackers with a pathway into connected systems.

This makes cybersecurity challenges in manufacturing an increasingly important concern for organizations of every size. Manufacturers face a unique security environment because their technology landscape often includes both traditional IT systems and operational technology. Some production systems may also depend on legacy software that was not originally designed for today’s connected environments.

AI-powered cybersecurity tools can analyze large amounts of software and security data, identify unusual patterns, assist with vulnerability detection, accelerate software analysis, and help security teams prioritize potential risks.

Why Manufacturing Software Is Becoming a Bigger Cybersecurity Target

Manufacturing organizations have become attractive targets for cybercriminals because their systems often contain valuable information and control important business operations.

Manufacturers may store:

• Product designs
• Engineering documentation
• Intellectual property
• Customer information
• Supplier information
• Production data
• Financial information
• Operational data
• Software source code
• Machine configurations

A successful cyberattack can therefore create both financial and operational consequences. Manufacturing environments can also be difficult to secure because they may contain a mixture of:

• Modern cloud applications
• On-premise software
• Legacy applications
• Industrial control systems
• IoT devices
• APIs
• Networked machines
• Third-party applications
• Remote access systems

The result is a large and complex attack surface.

Top Cybersecurity Challenges in Manufacturing Software

1. Legacy Manufacturing Software

One of the biggest cybersecurity challenges in manufacturing is the continued use of legacy software.

Many manufacturing applications were developed years or even decades ago. They may still be essential to production operations, making replacement difficult.

Legacy systems may have:

• Outdated libraries
• Unsupported operating systems
• Weak authentication mechanisms
• Limited logging
• Hard-coded credentials
• Older encryption methods
• Unpatched vulnerabilities
• Poorly documented architecture

Replacing these systems can be expensive and disruptive.

As a result, organizations often need to secure legacy applications while gradually modernizing them.

AI-powered software analysis can help security teams understand older applications by analyzing source code, binaries, dependencies, configurations, and application behavior.

This can make it easier to identify potential weaknesses before modernization or migration.

2. Increasing IT and OT Connectivity

Traditionally, IT systems and operational technology systems were more isolated.

Today, manufacturers increasingly connect production environments with enterprise applications, cloud platforms, analytics systems, and remote management tools.

This connectivity provides significant operational benefits.

However, it can also create new attack paths.

If an attacker compromises an enterprise application and can move into an OT environment, the consequences could be serious.

Manufacturers therefore need security controls that consider both IT and OT environments.

AI can help analyze large quantities of network and system information to identify unusual activity and potential attack patterns.

3. Expanding Attack Surface

Every connected application, device, API, endpoint, and service can potentially introduce additional security risk.

Manufacturing environments may include hundreds or thousands of connected assets.

These can include:

• Industrial machines
• Sensors
• PLCs
• SCADA systems
• IoT devices
• Workstations
• Servers
• Cloud applications
• Mobile devices
• APIs
• Remote access systems

Maintaining an accurate inventory is therefore essential.

Organizations need to understand what assets exist, what software they are running, which systems communicate with each other, and where vulnerabilities may exist.

AI-powered discovery and analysis tools can assist security teams in processing this large volume of information.

4. Vulnerabilities in Manufacturing Applications

Software vulnerabilities are another major concern.

Manufacturing applications may contain vulnerabilities caused by:

• Insecure coding
• Outdated dependencies
• Improper authentication
• Weak authorization
• Poor input validation
• Misconfigured services
• Insecure APIs
• Exposed credentials
• Unpatched components

A vulnerability may remain unnoticed if organizations do not regularly assess their software.

Traditional security testing remains important, but AI can help accelerate the analysis process.

AI-powered tools can assist in identifying suspicious code patterns, correlating vulnerabilities, analyzing dependencies, and prioritizing security findings.

5. Third-Party Software and Supply Chain Risks

Manufacturing software rarely operates in isolation.

Organizations often depend on third-party applications, libraries, APIs, cloud services, hardware vendors, and technology partners.

A vulnerability in a third-party component can potentially introduce risk into the manufacturer’s environment.

Software supply chain security has therefore become an important part of manufacturing cybersecurity.

Organizations should understand:

• Which third-party components are being used
• Which versions are installed
• Whether known vulnerabilities exist
• What permissions third-party applications have
• How software updates are delivered
• How vendors access internal systems

AI can assist with dependency analysis and help security teams identify relationships between applications and their components.

6. Ransomware and Operational Disruption

Ransomware remains a serious concern for organizations that depend on digital systems.

For manufacturers, the consequences can extend beyond data loss.

A successful ransomware incident may interrupt production, delay shipments, disrupt supplier relationships, and create significant financial losses.

Manufacturing environments require strong protection against unauthorized access and malicious activity.

AI-powered security systems can analyze system activity and identify patterns that may indicate suspicious behavior.

However, AI should be part of a broader cybersecurity strategy that includes access controls, network segmentation, backups, incident response, patch management, and employee awareness.

7. Insecure Remote Access

Remote access has become an important operational requirement.

Manufacturing engineers, IT teams, equipment vendors, and support personnel may need remote access to systems.

However, poorly secured remote access can create significant risks.

Organizations should carefully manage:

• Authentication
• Authorization
• Privileged access
• Remote desktop services
• VPN access
• Vendor access
• Session monitoring

AI can help identify unusual access patterns, such as logins from unexpected locations or unusual activity occurring outside normal operating patterns.

8. Poor Visibility Into Software Architecture

Security teams cannot protect systems effectively if they do not understand how those systems work.

This can be particularly difficult when organizations have inherited complex manufacturing applications with limited documentation.

Security teams may struggle to answer questions such as:

• What components does the application contain?
• Which APIs does it use?
• What external systems does it communicate with?
• Which libraries are included?
• Where are sensitive functions located?
• What data does the application process?
• Which components are outdated?

AI-powered reverse engineering and software analysis can help reconstruct application structures and identify important components.

This can be especially useful for legacy manufacturing software.

9. Insufficient Security Testing

Manufacturing applications should be tested throughout their lifecycle.

However, security testing can sometimes be performed only before major releases.

This can leave vulnerabilities undiscovered between testing cycles.

Security practices can include:

• Vulnerability assessments
• Penetration testing
• Static application security testing
• Dynamic application security testing
• Software composition analysis
• Code review
• Configuration testing
• API security testing

AI can complement these approaches by helping security teams analyze large amounts of code and security data more efficiently.

10. Lack of Skilled Cybersecurity Professionals

Manufacturing organizations often face a shortage of professionals who understand both cybersecurity and industrial environments.

OT security requires knowledge of manufacturing operations as well as security principles.

AI can help security teams by automating certain analysis tasks and reducing the amount of manual work required to identify potential issues.

This does not eliminate the need for skilled cybersecurity professionals.

Instead, AI can act as a force multiplier for security teams.

How AI Can Help Improve Manufacturing Cybersecurity

AI is becoming increasingly useful in cybersecurity because modern environments generate enormous amounts of data.

Security teams may need to analyze:

• Source code
• Application logs
• Network traffic
• Vulnerability reports
• Configuration files
• System behavior
• Software dependencies
• Authentication events
• Endpoint activity

AI can help process this information and identify patterns more efficiently.

1. AI-Powered Vulnerability Detection

AI can assist in identifying potentially vulnerable patterns in software.

For example, an AI-powered application security tool can analyze source code and identify areas that may require further investigation.

Potential findings could involve:

• Injection risks
• Authentication weaknesses
• Insecure data handling
• Hard-coded secrets
• Unsafe functions
• Vulnerable dependencies
• Access-control issues

AI-generated findings should still be validated through appropriate security testing and expert review.

2. AI-Powered Reverse Engineering

Reverse engineering can be particularly valuable when manufacturers have applications with limited source-code documentation.

AI can assist analysts in understanding:

• Application components
• Functions
• Dependencies
• Data flows
• API interactions
• Control flows
• Potential security-sensitive areas

Instead of manually analyzing every component, security professionals can use AI to accelerate discovery and focus attention on the most important areas.

This can significantly improve the efficiency of legacy application assessments.

3. Faster Software Security Analysis

Large manufacturing applications can contain thousands or millions of lines of code.

Manually reviewing every part of a large application is difficult.

AI can help prioritize areas that deserve closer attention.

For example, an AI system may identify components associated with authentication, data processing, external communication, or privileged operations.

Security analysts can then investigate these areas first.

4. Intelligent Vulnerability Prioritization

Finding vulnerabilities is only part of the cybersecurity challenge.

Organizations also need to determine which vulnerabilities should be fixed first.

AI can help prioritize findings based on factors such as:

• Severity
• Exploitability
• Asset importance
• Exposure
• Business impact
• Dependency relationships

This can help security teams focus their limited resources on the most important risks.

5. Detecting Unusual Behavior

AI can also help detect anomalies.

Machine learning models can establish patterns of normal activity and identify deviations.

For example:

A manufacturing system normally receives a specific type of communication from a known application.

Suddenly, the system receives unusual requests at an unexpected time.

An AI-powered monitoring system may flag this behavior for investigation.

Anomaly detection can therefore complement traditional rule-based security monitoring.

6. AI-Assisted Security Documentation

Manufacturing software is often difficult to document manually.

AI can help generate or organize documentation related to:

• Application architecture
• Software components
• APIs
• Dependencies
• Security findings
• System workflows
• Configuration information

Better documentation can make security assessments and modernization projects more efficient.

7. AI for Secure Software Modernization

Legacy modernization is a major challenge for manufacturers.

Organizations may want to migrate old applications to modern architectures without disrupting production.

AI can assist by analyzing existing software and helping development and security teams understand how legacy systems work.

This can support activities such as:

• Code analysis
• Dependency discovery
• Architecture mapping
• Documentation generation
• Code refactoring
• Vulnerability identification
• Modernization planning

AI therefore has the potential to support both security and modernization initiatives.

AI and VAPT for Manufacturing Software

Vulnerability Assessment and Penetration Testing (VAPT) remains an important component of cybersecurity.

VAPT can help organizations identify vulnerabilities and evaluate how security controls perform against potential attacks.

AI can complement VAPT by accelerating certain activities.

For example, AI can help:

• Analyze application structures
• Identify potentially vulnerable components
• Prioritize findings
• Correlate security information
• Assist with security reporting
• Identify suspicious code patterns

However, AI should complement rather than replace professional security testing.

Human security experts are still important for validating findings, understanding business context, evaluating exploitability, and determining appropriate remediation.

Benefits of AI-Powered Manufacturing Cybersecurity

When implemented correctly, AI can provide several benefits.

Faster Security Analysis

AI can process large amounts of information more quickly than manual analysis alone.

AI systems depend heavily on the quality and relevance of their inputs.

3. Validate AI Findings

AI-generated security findings should be reviewed and validated.

4. Maintain Human Oversight

Security professionals should remain involved in high-impact decisions.

5. Protect Sensitive Data

Manufacturing software can contain intellectual property and confidential information.

Organizations should establish appropriate controls for how data is processed and stored.

6. Integrate AI With Existing Security Tools

AI should complement existing security processes rather than operate as an isolated solution.

7. Continuously Monitor Performance

Organizations should evaluate whether AI tools are producing useful and accurate results.

The Future of AI in Manufacturing Cybersecurity

The role of AI in cybersecurity is likely to expand as manufacturing environments become more connected.

Future security platforms may increasingly combine:

• AI
• Machine learning
• Generative AI
• Automated security analysis
• Software composition analysis
• VAPT
• Threat intelligence
• Behavioral analytics
• Reverse engineering
• Security orchestration

AI agents may also help security teams investigate alerts, correlate findings, generate reports, and recommend remediation steps under appropriate human supervision.

For manufacturing organizations, this could create a more proactive security model.

Instead of discovering security problems only after an incident, organizations can increasingly identify and address potential risks earlier in the software lifecycle.

Why Manufacturing Companies Should Prioritize Software Security

Manufacturing cybersecurity is no longer limited to protecting office computers.

Modern manufacturing depends on software at almost every stage of the operation.

Software controls production processes, communicates with machines, manages inventory, processes business information, and connects organizations with suppliers and customers.

A weakness in one application can potentially affect multiple connected systems.

For this reason, software security should be considered throughout the application lifecycle.

Security should be incorporated during:

• Software development
• Testing
• Deployment
• Integration
• Modernization
• Maintenance

Organizations that treat cybersecurity as an ongoing process rather than a one-time assessment can improve their ability to manage evolving threats.
