The Australian Cyber Security Centre (ACSC) [1] [2] [3] [4] [5] [6], in collaboration with CISA [1] [2] [3] [4], the FBI [3], the NSA [3] [5], and international partners [1] [2] [3] [4], has released a new guide titled Principles of Operational Technology Cybersecurity [1] [2]. This guide emphasizes the importance of understanding risks associated with business decisions that may compromise OT cybersecurity and outlines six fundamental principles for enhancing cybersecurity in operational technology (OT) environments.
Description
Developed through cooperation among cybersecurity agencies from various countries, the guide focuses on critical infrastructure sectors such as water, energy [5], and transportation [5], highlighting the importance of public safety and the need to strengthen cybersecurity defenses in OT environments. The principles include prioritizing safety, understanding critical systems [1] [5], safeguarding OT data [1], implementing network segmentation, ensuring supply chain security [1], and training skilled personnel to respond effectively to cyber incidents [1]. Organizations are encouraged to review best practices outlined in the guide to establish necessary cybersecurity controls and mitigate residual risks [3]. For more information [2], organizations can refer to the Industrial Control Systems page and the Joint Cybersecurity Advisory Immediate Actions to Reduce Exposure Across Operational Technologies and Control Systems [2] [3].
Conclusion
The Principles of Operational Technology Cybersecurity guide provides valuable insights for organizations operating in OT environments to enhance their cybersecurity defenses and protect critical infrastructure. By prioritizing safety [1], understanding critical systems [1] [5], safeguarding data [1], implementing network segmentation, ensuring supply chain security [1], and training skilled personnel [1], organizations can effectively respond to cyber incidents and mitigate risks. It is essential for organizations to implement the best practices outlined in the guide to strengthen their cybersecurity posture and safeguard against potential threats in the future.
