The Australian Cyber Security Centre (ACSC) has refreshed its Essential Eight implementation guide, which now sees all of the Essential Eight strategies become essential.

"The Essential Eight Maturity Model now prioritises the implementation of all eight mitigation strategies as a package due to their complementary nature and focus on various cyber threats," the ACSC said.
Compared to its last release, the maturity model adds a new maturity level zero, which is defined as environments with weaknesses that cannot prevent commodity attacks in level one, and the levels are aligned to cyber tradecraft and tactics used.

"Depending on an adversary's overall capability, they may exhibit different levels of tradecraft for different operations against different targets. For example, an adversary capable of advanced tradecraft may use it against one target while using basic tradecraft against another," the guide states.

While the guide has the same overall headings as its previous iteration, many of the details have changed, becoming more precise while also reducing various timeframe recommendations.
