Exida, a global supplier of functional safety, security, and alarm management services and certifications, has begun offering an integrated testing package, which the company says evaluates the most important attributes of an automation product—functional safety, functional security, and availability. The move could help improve safety, functional security, and availability related to automation system integration and process control software upgrade implementations.

Exida says its Functional Integrity Certification is the only independent, third party assessment that examines functional safety, security, and availability attributes of an automation product through assessment of its design, testing, and manufacturing.

For functional safety, a product and its development process are evaluated per the international standard IEC 61508 to determine its Safety Integrity Level (SIL). The SIL level is a measure of the probability that a product will perform its intended protection function when needed.

Functional security assesses a product's resiliency to manipulation that could cause it to behave differently than was intended. A combination of network robustness testing, security feature assessment, and software development process assessment helps detect and avoid vulnerabilities and systematic design faults. The certification is based on the ISA Security Compliance Institute (ISCI) Embedded Controller Security Assurance (ECSA) test specification.

Finally, an availability assessment ensures the dependability of automation products in critical applications. Exida uses modeling and probabilistic methods, combined with empirical data, to help predict product reliability.
