Security threats can come in many forms: physical or digital, internal or external, malicious or unintentional. No single security product, technology or methodology is sufficient.
Industrial security must be holistic. It should extend from the enterprise through the plant level and even out to end devices. It should address risks across people, processes and technologies, and should involve collaboration among IT and OT personnel.
By focusing on three key aspects of a holistic industrial security approach, companies can better manage potential threats and build more secure systems.
- Security assessment: Understand your risk areas and potential threats
- Defense-in-Depth security: Deploy a multi-layered security approach that establishes multiple fronts of defense
- Trusted vendors: Verify that your automation vendors follow core security principles when designing their products
