Beyond the Essential Eight: Exposing Attack Chains in ASD’s New Era

How to identify hidden attack paths, prioritise high-impact fixes, and meet ASD’s new baseline.

Australia’s cyber baseline is shifting with ASD’s release of Essentials for enterprise IT. Building on the Essential Eight across eight domains and three priority phases mapped to MITRE ATT&CK, the new framework demands evidence that controls work in practice rather than static checklist compliance. But adversaries don’t follow checklists, they exploit the gaps between them, chaining seemingly minor weaknesses like exposed services, stale credentials, and legacy configurations into compound attack paths that single findings miss.

In this session, we dive deep into Tenable One Adversary View, powered by the frontier cyber reasoning of Anthropic’s Claude Mythos 5 and guided by Hexa AI. See how it transforms the scan data you already collect to reveal viable vulnerability chains, backed by raw evidence and the exact fixes needed to break them. Want a sneak peek? Explore our interactive walkthrough to uncover hidden threats through an adversary’s eyes, then join the live webinar to learn how to operationalise these attack paths into audit-ready compliance evidence for ASD’s new baseline.

What we’ll cover:

• Navigate ASD’s Essentials for Enterprise IT: Understand the transition from the Essential Eight, the 3 priority phases, and how actions map to MITRE ATT&CK.
• See Your Attack Surface Through Adversary View: How Claude Mythos 5 evaluates your environment holistically, connecting scattered, low-signal telemetry to expose viable attack chains before adversaries exploit them.
• Ranked Actions, Not More Findings: How Adversary View pinpoints the exact fix that breaks the path, and how teams can execute rapidly using Tenable Hexa AI.
• Turn Remediation into Audit-Ready Evidence: Map resolved attack paths directly back to Essentials controls, starting with Phase 1 (Boundary & Identity services).
• Govern AI Responsibly: ASD’s expectations for managing AI as an asset, a threat, and a defensive capability under executive accountability frameworks.

Public ciblé
CISOs, SecOps and IT leaders, risk managers, and GRC teams in government, critical infrastructure, and enterprise who need an attacker’s-eye view of risk and actionable evidence that their controls hold up.
