Episode 379 – Cybersecurity information sharing – OT-ISAC Summit 2023 highlights


In this interview, both John and Thian introduce the history of ISACs (formed in 1999, subsequent to the 1998 signing of U.S. Presidential Decision Directive-63), and in particular, the creation of OT-ISAC (Operational Technology Information Sharing and Analysis Centre) as one of the key trusts of the Cyber Security Agency of Singapore’s “OT Cybersecurity Masterplan 2019 to facilitate the sharing of information.

Reflecting on the journey from conceptualization to today, Thian Chin remarked that “OT-ISAC has become that safe harbour the platform for the organisations of the different parties with vested interest to different business lines come together to share, because their common goal is how do we then exchange information to reduce the risks that caused by threat actors.”

Other topics covered in the interview include:

  • The types of information being shared – such as strategic threat landscape including cyber incidents and vulnerabilities, standards and best practices, and TTPs.
  • Closing the cultural / communication gap between the engineers and the IT cybersecurity practitioners because “because the problem statement they’re dealing with is the same. It’s a threat actor out there to try to disrupt.”
  • The maturing of conversations from beyond terminology such as zero trust, air gap to actual implementation
  • What does success mean in information sharing – diversity of opinions – in particular, including C-suite in cybersecurity conversations, and more more stakeholders coming forward to share real-life case studies of actual incidences.
