Hazardex 2019 Conference Presentations - Managing Cybersecurity and Functional Safety

Author : Sarabjit Purewal - HSE Principal Specialist Inspector

19 November 2018

Cybersecurity is a relatively new topic that industry is becoming familiar with. New standards such as IEC 62443 are at an advanced stage of completion. New guidance is being published by the National Cybersecurity Centre (NCSC) and new regulations such as security of Network Information Systems (NIS) have come on statute in 2018. This presentation will explore the key technical and organisational issues in managing safety systems securely.

Cybersecurity impacts on many systems that are designed for functional safety where the design methods do not assume that someone is deliberately trying to introduce malware into the systems. So what are the issues around managing safety systems from a cybersecurity perspective?

Other than the issues in managing safety systems securely, the presentation will also explore technical issues around risk assessments, risk appetite, and managing cybersecurity including supply chain to organisational issues of leadership, and competency.


Sarabjit Purewal leads an electrical, control and cybersecurity team in the onshore major hazards section of the Health and Safety Executive (HSE). 

He is a chartered engineer, an associate of City and Guilds Institute, and member of the Institution of Engineering and Technology. Sarabjit started his career with the CEGB in the electricity supply industry working on automation of conventional and nuclear power stations.

He later worked with Kennedy and Donkin Consulting Engineers as the engineering manager of the Power Group, and then with Mott MacDonald as divisional director, before moving to the Health and Safety Executive working on various technical and policy issues.
