Cyber hygiene is a first line of defence to strengthen security posture

Good cyber hygiene is essential for strong cyber defence and resilience against attacks. The Australian Cyber Security Centre has released an advisory urging Australian organisations to adopt an enhanced cyber security posture urgently.

Escalating cyber risk

There is increasing concern that the rapid escalation of the Ukraine-Russia conflict and Australia’s sanctions against Russia might provoke state-based attackers seeking retribution. Australia presents a large attack surface with its critical infrastructure connected to the internet – hospitals, electricity, gas, water, tolls, finance systems, and so much more. Furthermore, many opportunist cybercriminal operators from other countries may exploit the chaos for their agenda.

While the ACSC has not reported any current or specific threats to Australian organisations, it warns that the volume, nature and impact of cyber attacks is expected to continue as the conflict plays out. The ACSC recommends urgently reviewing and improving cyber security incident detection, mitigation, and response measures, including ensuring that logging and detection systems are updated and functioning. Organisations should also make sure their cyber incident response plans are up to date and review their business continuity planning to ensure they can keep operating if they are affected by any cyber fallout.

Cyber hygiene

Microsoft and Satalyst cyber security experts recommend the following cyber security hygiene practices to strengthen security posture and proactively protect against potential threats.

  1. Enable multifactor authentication
  2. Apply least privilege access and secure the most sensitive and privileged credentials
  3. Review all authentication activity for remote access infrastructure
  4. Secure and manage systems with up-to-date patching
  5. Use anti-malware and workload protection tools
  6. Isolate legacy systems
  7. Enable logging of key functions
  8. Validate your backups
  9. Verify your cyber incident response plans are up to date

ACSC’s Essential Eight mitigation strategies

While no set of mitigation strategies are guaranteed to protect against all cyber threats, the ACSC recommends organisations to implement eight essential mitigation strategies known as the Essential Eight. The Essential Eight is a baseline of mitigation strategies, which makes it much harder for adversaries to compromise systems.

The mitigation strategies that constitute the Essential Eight are: application control, patch applications, configure Microsoft Office macro settings, user application hardening, restrict administrative privileges, patch operating systems, multi-factor authentication and regular backups.
