Background / What has happened?
There has been a historical pattern of cyber attacks against Ukraine that have had international consequences. Malicious cyber activity could impact Australian organisations through unintended disruption or uncontained malicious cyber activities.
While the ACSC is not aware of any current or specific threats to Australian organisations, adopting an enhanced cybersecurity posture and increased monitoring for threats will help to reduce the impacts to Australian organisations.
Mitigation / How do I stay secure?
The ACSC recommends that organisations urgently adopt an enhanced cyber security posture. This should include reviewing and enhancing detection, mitigation, and response measures.
Organisations should ensure that logging and detection systems in their environment are fully updated and functioning and apply additional monitoring of their networks where required.
Organisations should also assess their preparedness to respond to any cyber security incidents, and should review incident response and business continuity plans. The ACSC has published to assist organisations to produce an incident response plan.
The ACSC strongly recommends organisations implement the Essential Eight mitigation strategies from the ACSC’s as a baseline. This baseline, known as the , makes it much harder for adversaries to compromise systems. The Essential Eight mitigation strategies are:
