This is why in 2018, the Australian energy sector regulator, Australian Energy Market Operator (AEMO), released the Australian Energy Security Cyber Security Framework (AESCSF) in cooperation with industry and government partners.
The AESCSF is unique, in that it is not very closely aligned with (although may have been informed by) the industry standard for information security (ISO/IEC 27001), the Australian Government Information Security Manual (ISM) or the US NIST Cyber Security Framework.
It is in fact based on the US Department of Energy’s Cybersecurity Capability Maturity Model (ES-C2M2).
The AESCSF focuses, as it should, on the unique needs of the energy sector, including the use of Operational Technology (OT), which manages physical processes. It also includes ‘Anti-Patterns’, which seek to identify and weed out bad practices that can creep in and undermine security efforts if not kept under control or rather altogether avoided.
Assessment and reporting by energy sector operators against the requirements of the AESCSF is expected annually. Although reporting is not yet mandatory, this is expected to be changed imminently.
