Where businesses carry out worse than the Essential Eight

The mitigation methods the place the bottom proportion of businesses achieved maturity stage 2 had been:

Australian authorities businesses carried out higher than Maturity Level 2 for the next methods:

• Limit Microsoft Office macros (68%).

Agencies that don’t sustain with Essential Eight updates will basically be at higher threat of compromise by unhealthy actors and can endure a higher impression if a compromise happens.

Legacy IT additionally performs a task within the cybersecurity hole

There had been some areas of concern for ASD, together with the quantity of incident experiences obtained.

• The proportion of entities reporting safety incidents to ASD remained low, with solely 32% reporting not less than half of the incidents noticed on their networks in 2024.

The ASD concluded that businesses ought to proceed to implement up to date Essential Eight mitigation methods of their networks as much as not less than maturity stage 2, in keeping with present necessities.

It additionally really useful that Australian public sector businesses improve cybersecurity incident reporting and share cyber menace info with ASD, implement methods for managing legacy IT now and sooner or later, and preserve a response plan to accidents and to follow it not less than each 2 years.
