Functional Safety and Industrial Cybersecurity- what’s the connection? In this short explanatory white paper, we will discuss how a bad Industrial cybersecurity posture can degrade Functional Safety to be almost ineffective, in protecting assets, people and the environment. Thus having proper Industrial Cybersecurity is a pre-requisite to having proper Functional Safety. What is Functional Safety all about? Functional Safety is a specialized domain within the Safety world, which deals …

Here’s a guide to IEC 62443. After going through this (somewhat short) IEC 62443 guide, you will understand how it helps you secure your Industrial Automation and Control Systems (IACS for short) against cyber threats. Let us understand more about it, why it was developed and where it can be used. What is IEC 62443? IEC 62443 is not a single document, but a set of standards, practices and …
If you have been working in the field of Industrial Control Systems cyber security (ICS security) or in the broader Operational Technology cybersecurity domain (OT security) then you may have heard of the standard ANSI/ISA/IEC 62443, referred to these days as simply IEC 62443. This standard has certain Foundational Requirements that are important and these are explained in short here. This short guide will explain these IEC 62443 Foundational …
In this short guide we will learn something about proof testing Safety Instrumented Systems. What is a Proof Test of a Safety Instrumented System? Proof testing is the process by which the end user actually tests whether the Safety Instrumented System is actually working as intended. A Proof test has to be carried out for every Safety Instrumented Function (SIF for short). For example, if a SIF is supposed …
In this short guide, we will take a look at the ANSI ISA S84 standard. What is ISA S84.01? This is the Functional Safety standard published by ISA (International Systems and Automation Society)’s S 84 committee. This is applicable to functional safety in the process industries. The standard was initially published as ANSI/ISA S84.01:1996 and was recognized by OSHA as a “generally accepted good engineering practice” via their letter …
In this small guide we will understand Safety Instrumented System requirements. But first we answer some basic questions such as, What is a Safety Instrumented System? The simplest explanation of a Safety Instrumented System (SIS for short) is ” a system comprised of active elements such as sensors, logic solvers and actuators, working together as a system, which acts to reduce the risk of an unwanted event in a …
