Our cyber security products span from our next gen SIEM used in the most secure government and critical infrastructure environments, to automated cyber risk reporting applications for commercial and government organisations of all sizes.
In light of recent world events, many governments are strongly advising organisations to monitor for cyber-threats and take steps to enhance their cyber security posture. In Australia, this advice has come in the form of the latest ACSC advisory dated March 4th 2022. It outlines the increasingly hostile malware attacks, ransomware environment and the state-sponsored targeted attacks on network devices.
Links are also provided to CISA and NSA publications for guidance on securing networks, other ACSC and Partner reports as well as a comprehensive Appendix that details common cyber attack and mitigation techniques in a handy threat taxonomy aligned to the MITRE ATT&CK® matrix.
The advice is intended for entities to take the appropriate action to protect their systems and networks. It is drawn from observations in the field and the approaches and techniques currently being used by attackers. In summary the Tactics are:
The advisory reminds readers to review their detection, mitigation and response measures in the current threat environment.
Helpfully, it also contains a lengthy Appendix that identifies particularly concerning MITRE ATT&CK® Tactics and their corresponding Techniques categorised by industry sector and malware type. Readers will note that this is a significant and lengthy list of considerations, particularly as each technique may have several alternate or complementary mitigation procedures, that a defender might institute.
An important consideration is, irrespective of the level of defence in place, how do you incorporate the monitoring of these threats and visualise attacks, as they are happening, as part of your Security Operations?
Some SIEM technologies have moved to quickly integrate the significant benefits of the MITRE ATT&CK® knowledge base into their detection, mitigation and response capabilities. For example, in the latest Huntsman Enterprise SIEM (V7) the associated detections of events and alerts are automatically visualised on MITRE ATT&CK® heatmap displays to show the tactics and techniques currently detected across the monitored environment and their progress towards their malicious objective.

Each cell is colour coded, to highlight the scale, number or volume of observations. With this sort of information at hand, it can quickly be used to gain an understanding of what attacks are being experienced, how far they are along the “kill chain” and importantly the relative importance of a specific response.
Of course, monitoring alone isn’t enough. Controls need to be in place and operating effectively to defend systems against attacks too. This means configuring in-built security settings as well as deploying prevention, containment and recovery controls to enhance your cyber security posture.
The ACSC advisory also reminds organisations to remain vigilant against ransomware attacks and the importance of good cyber hygiene in those efforts. Again, this has been a major focus of the new Huntsman Security SmartCheck for Ransomware solution which measures and reports on the effectiveness of 12 key security controls to enhance your cyber posture and combat ransomware, one of today’s most prevalent threats.

In early August 2023, the latest joint advisory on persistent vulnerabilities was issued by the intelligence and security agencies of the “Five-eyes” community. These joint advisories are becoming more common. Perhaps recognising the growing importance of shared security information and the common nature of many of the threats faced – the weight they carry makes […]Read more
The quality of your risk assessment and the security information it provides is important; if you plan to use it to actively manage your operational and cyber resilience activities. Organisations are constantly exposed to a rapidly changing threat environment, so you really need a similarly rapid evidence-based feedback system that informs you of the ongoing […]Read more
The UK market has its own regulators, security standards and challenges. And while rulings from SEC in the US or the Australian Prudential Regulation Authority (APRA) in Australia don’t apply to UK companies, for the most part, the observations are undoubtedly relevant and the resulting advice instructive. It would be wrong to think UK financial […]Read more

Supply chain risk is an area of cyber security that demands the ongoing attention of every enterprise; because it can make the difference between being resilient or not. It’s no surprise that insurers warn that the vulnerability of supply chains is potentially a systemic risk that can quickly propagate across supply chain dominated industries. Organisations […]Read more
