Industry increasingly relies upon safety systems to maintain and protect operating assets.
Systems comprised of electrical or electronic elements have been widely used to perform safety functions in most application sectors
The oil and gas industry, nuclear plants, and transport sector, to name but a few, all rely heavily on functional safety.
The functional safety compliance requirements of IEC 61508 and IEC 61511 and other standards covering safety-related systems are increasingly being specified in procurement specifications in a wide range of sectors and increasingly diverse applications.
The standards are also being used not just for functional safety but also for asset protection.
Allied to the need to have adequate levels of functional safety to meet safety / environment risks is the need to ensure that safety-related systems are properly protected against cyber-attacks
