Dr. William Goble and Todd Stauffer of exida will be presenting a free webinar through IEEE Spectrum on Tuesday, 21 September 2021, 2pm ET titled Design of Safety Critical Devices - Resolve the Conflict. The webinar will explain how you can reduce time to market and development costs while optimizing…
Functional Safety is a field of engineering where critical design goals include high reliability and predictable failure (fail-safe). The IEC 61508 family of standards are performance-based standards for functional safety that are commonly applied to the design and development of automatic protection systems in a variety of applications (process industry,…
In this video, Dr. Steve Gandy explains failure rates from the IEC 61511 perspective. He talks about where the failure rates come from, why we need tp make sure we have valid failure rates, and what do we mean by valid failure rates.
This short course (2 hours) provides an overview of the IEC 62443 series of standards including the information that product marketing, sales, and senior leadership needs to know about these standards. In addition, the course talks about marketing strategies for getting out the word to your customers that your products…

Failure Modes, Effects, and Diagnostics Analysis (FMEDA) is a staple in functional safety engineering for design & development of automatic protection systems to the IEC 61508 family of standards (IEC 62061, ISO 26262, IEC 61511). FMEDA is the most common technique for quantitative evaluation of safety and reliability performance metrics and for evaluating whether a product will fail in a predictable manner (fail-safe). Experienced engineers know that FMEDA results, however, are only as good as the failure rate data used to create them and the associated component reliability database (CRD). A new CRD from exida overcomes limitations of current industry reliability handbooks to deliver more accurate results that helps product designers reduce cost and time to market. Integration into the exida FMEDAx tool minimizes the chance of human error and reduces engineering time.

With the drive for digitalization and the Internet of Things the expression “Content is King”, coined by Bill Gates, has now been replaced by “Data is King”. This is especially TRUE in functional safety where the safety and reliability predictions generated from a Failure Modes, Effects & Diagnostics Analysis (FMEDA)…

Two common gaps exida encounters when evaluating vendor compliance against the IEC 62443-4-1, IEC 62443-4-2 and IEC 62443-3-3 standards are: Inadequate or unclear Security Guidelines. A lack of documentation on the security audit records (AKA logs). Improving compliance in these areas is also a very cost-effective means of improving security.…

As the number of major cybersecurity incidents in 2021 continue to rise many organizations are looking at assessing their cybersecurity risks with an increased focus. There are several methodologies outlined for conducting cybersecurity risk assessments including the IEC 62443-3-2 standard (for more information on the IEC 62443-3-2 methodology for risk assessment see: https://gca.isa.org/blog/cybersecurity-risk-assessment-according-to-isa-iec-62443-3-2) and Consequence-driven Cyber-informed Engineering (CCE) outlined by the Idaho National Laboratory (https://inl.gov/cce/ ). While the IEC 62443-3-2 provides options for considering or not considering likelihood, CCE is a fully consequence driven approach. This raises the question of whether or not cybersecurity risk assessments should consider likelihood? In this webinar we will compare the two different approaches to cybersecurity risk assessment looking at the advantages and disadvantages of each approach to provide practical guidance on cyber risk assessment best practices.
