Whether you’re an SME manufacturer or a larger enterprise, this guide will equip you with the knowledge and tools needed to navigate the complex world of manufacturing cybersecurity.
1. Understanding Application Security in Manufacturing
1.1 Defining Application Security for Manufacturing
Application security in manufacturing refers to the measures and practices implemented to protect software applications from threats throughout their lifecycle. In the context of manufacturing, this encompasses a wide range of systems, from production line control software to supply chain management applications and enterprise resource planning (ERP) systems.
The manufacturing sector faces unique challenges when it comes to application security:
- Legacy systems that may lack modern security features
- Interconnected networks of devices and sensors (Industrial Internet of Things)
- Complex supply chains with multiple potential entry points for attackers
- Valuable intellectual property and trade secrets that require protection
CMMC compliance adds another layer of complexity to application security in manufacturing. The Cybersecurity Maturity Model Certification (CMMC) is a framework designed to protect sensitive information within the Defense Industrial Base (DIB) supply chain. For manufacturers working with the Department of Defense, achieving and maintaining CMMC compliance is crucial.
“CMMC compliance isn’t just about checking boxes,” notes Jason Vanzin. “It’s about implementing a comprehensive security program that protects your entire digital ecosystem, including all your critical applications.”
To truly understand the importance of application security in manufacturing, consider the potential consequences of a breach:
- Production downtime
- Intellectual property theft
- Financial losses
- Damage to reputation
- Regulatory fines and penalties
By prioritizing application security, manufacturers can mitigate these risks and create a more resilient, trustworthy business environment.

3. Essential Testing Methods for Manufacturing Applications
3.1 Implementing SAST, DAST, and CI/CD Practices
To ensure the security of manufacturing applications, it’s crucial to implement comprehensive testing methodologies throughout the development lifecycle:
Static Application Security Testing (SAST)
SAST involves analyzing source code to identify potential security vulnerabilities before the application is deployed. Benefits for manufacturing applications include:
- Early detection of coding errors and security flaws
- Reduced costs associated with fixing issues in production
- Improved compliance with industry standards and regulations
Dynamic Application Security Testing (DAST)
DAST simulates real-world attacks on running applications to identify vulnerabilities that may not be apparent in static code analysis. Advantages for manufacturers include:
- Detection of runtime and environment-specific vulnerabilities
- Validation of security controls and configurations
- Identification of issues related to third-party integrations
Continuous Integration and Continuous Deployment (CI/CD)
Integrating security into CI/CD pipelines is essential for maintaining application security throughout rapid development cycles. Key benefits include:
- Automated security testing at every stage of development
- Faster identification and remediation of vulnerabilities
- Consistent application of security policies across all deployments
Jason Vanzin emphasizes the importance of comprehensive testing: “In manufacturing, where downtime can be catastrophic, thorough application testing isn’t just good practice – it’s a business imperative. Combining SAST, DAST, and secure CI/CD processes creates a robust defense against potential threats.”
