FOUNDATIONS FOR MODERN DEFENSIBLE ARCHITECTURE

Summary from the TLDR InfoSec newsletter

The Australian Signals Directorate (ASD) has published a modern defensible architecture framework based on zero trust principles ("never trust, always verify," "assume breach," and "verify explicitly") and five key pillars (Identity, Devices, Networks, Applications/Workloads, and Data), emphasizing that organizations should prepare for "when" not "if" a cyber incident occurs. These principles, based on zero trust and secure-by-design practices, aim to enhance cyber resilience and protect critical assets. Organizations can use the Foundations to build a strong security framework adaptable to evolving technologies and threats.
