Issue 20:  Key Takeaways from Understanding IEC 62443 Webinar

by Smart Grid Forums on October 29, 2021

Cyberweekly No.20-1

IEC 62443 is a series of standards that provide organisations across multiple sectors with a robust framework to manage and mitigate security vulnerabilities in industrial automation control systems. By segmenting an organisation’s cybersecurity risks into key zones, the standard enables significant reductions in cybersecurity risk and costs.

Implementing IEC 62443 is everyone’s responsibility and must be better understood and fully embraced by power grid operators, solution providers and system integrators alike, to realise its full benefits.

During this month’s webinar on Understanding IEC 62443, speakers from DNV, Enexis and Fortinet addressed the fundamental building blocks of the standard and examined how it can best be applied in combination with ISO 27001 to provide a holistic cybersecurity approach for IT/OT converged environments.

There is no denying that to date cybersecurity has been an afterthought and often applied in an ad-hoc manner, but events of the past year and in particular the Colonial Pipeline Ransomware attack, have brought home just how critical a more structured and systematic approach to cybersecurity is now required.

The Ukraine cyberattacks demonstrated that you may have the most advanced security features in place but still get caught out by cybersecurity basics. IEC 62443 provides a robust, common sense, cost-efficient approach to securing the power grid in line with your particular risk profile and your particular security goals. Taking the guess work out of next generation power grid cybersecurity.

REPORT: SANS & Fortinet. Effective ICS Cybersecurity Using the IEC 62443 Standard.
IEC 62443 is a set of ICS security standards written by ICS experts for ICS owners, manufacturers and integrators across a range of applications and sectors. It provides technical requirements that foster a cohesive approach to security that takes into account varying phases of maturity. Using a step-by-step process incorporating “maturity phases,” the Standard outlines a lifecycle approach as part of a cybersecurity program. By segmenting ICS into security zones, organizations can better focus mitigation efforts related to risk, vulnerabilities and compliance in both a localized and broad perspective within their ICS environment.

PRESENTATION: Fortinet. Adopting IEC 62443 across a wider range of power grid industrial automation control systems.
In this presentation Anton D’Hausey of Fortinet evaluates how IEC 62443 can be applied to a greater range of power grid systems and components. Specifically he addresses: Identifying the regulatory and commercial drivers for adopting IEC 62443 from a product supplier point of view. Evaluating lessons learnt from the integration of the standard into products for the power grid industrial automation control environment. Determining how the standard needs to evolve to ensure its ongoing fit with the evolving power grid IIoT based infrastructure and cybersecurity threat landscape.

WEBINAR: Smart Grid Forums. Understanding IEC 62443.
In this 60-min video speakers from DNV, Enexis and Fortinet provide insights into how organisations can evaluate and align IEC 62443 concepts, frameworks and controls with an accurate representation of cybersecurity risk to their operations. We clarify the fundamental building blocks of the standard, the benefits of applying it in combination with ISO 27001 in the power grid environment, the intricacies of the certification process, and how grid operators and product suppliers can work more collaboratively to ensure its widespread application.
