This is a 2nd top conference (Google Rank) in Automation and Control Theory. Paper combines ML, game theory and control theory (i.e., physics inspired ML settings) to defend against cyber-attacks in an application scenario.

Projects

  • CS CRC Threat Hunting project commenced in August.

Threat hunting is a powerful defence method where cyber security experts search through the target system to detect, locate, isolate and mitigate stealthy (insider or external) threats which cannot be detected by the existing security solutions such as IDS, IPS, Firewall and AntiVirus. Literature shows that dwell time for such stealthy threats may change from 50 days to 250+ days – the time during which the system will be at the attackers’ mercy. With the benefit of shortening the dwell time, data lake platforms provide strong data analytics capabilities and built-in templates to help create threat detection rules. However, understanding potential threats on a targeted system, building a hypothesis about the threat and carrying out an investigation using data analysis methods are left to human security experts. Hence, Threat Hunting becomes a multi-stage operation that requires deep cyber security expertise with decades of threat hunting experience and strong data analysis and programming capabilities. While there is a shortage of people with threat hunting capabilities worldwide, a single expert rarely collects all these capabilities. This project aims to address this critical expertise gap by bringing threat hunting capabilities to data analysts.  Given a threat intelligence regarding an attack campaign (e.g., ransomware, DDoS or cyber espionage campaign), the solution of this project ML to generate custom rules for data analysts to answer the questions including (i) Have we been hit? (ii) Are we susceptible?

  • Muhammed  Esgin, Chandra Thapa, Sharif Abuadbba are participating in the CSIRO  Innovate to Grow Cyber as mentors to SMEs. The program is running for 10 weeks where each mentor is tasked to help 5-6 SMEs.
  • Four new DSTG NGTF projects commenced: Towards Trustworthy Machine Learning Models (Talos),  Towards Fast Feedback Fuzzers for Discovering Vulnerabilities in Software Binaries (Kronos), Security Assessment Framework for Next Generation IP Networks, An Automated System for Rapid, Accurate Malware Analysis and Effective Triage

Events

  • Data61 and DSTG Cyber Security Summer School

Bringing together the Australian cyber security ecosystem.

The CSIRO’s Data61 & DSTG Cyber Security Summer School (CSSS) (https://research.csiro.au/csss/), in collaboration with the University of Queensland, is an annual summer school focusing on a range of cyber security topics, bringing the Australian cyber ecosystem together. The CDNG Technology and Science Conference (https://wp.csiro.au/cdng/), in collaboration with Macquarie University, is a first of its kind scientific and technology focused Cyber Defence Conference, with the aim to have the community of Cyber-Security under the “Next Generation Defence Technologies | Cyber Research” program in collaboration with DST-Data61 and partner universities meet together, expose relevant research activities and discuss future collaborations. This year, the two events will jointly be hosted at Customs House Brisbane, 22 to 24 November 2021.

Attendance is free, subject to invitation.

22 – 24 November 2021

  • SPS Special Session on Cyber Resilience and Antifragility in Complex Distributed Systems (CyRA 2021)

We are organizing a special session (CyRA) as part of the 2021 Self-Protecting Systems (SPS) workshop, which itself is co-hosted with ACSOS 2021. For more information:
https://research.csiro.au/distributed-systems-security/cyra2021/

The 2021 Special Session on Cyber Resilience and Antifragility in Complex Distributed Systems (CyRA 2021) will be part of the 3rd International Workshop on Self-Protecting Systems (SPS’21). It will be held in conjunction with the 2nd International Conference on Autonomic Computing and Self-Organizing Systems (ACSOS 2021), which will be taking a virtual format from 27 September to 1 October 2021.

We invite original research papers that have not been previously published and are not currently under review for publication elsewhere. All papers will be peer-reviewed by at least 3 international experts in the field. Acceptance/rejection will be based on relevance to the workshop topics, technical quality, originality, and presentation (coherent structure, readable figures, etc.). Novel ideas, papers showing promising early results (prior to comprehensive validation), or papers which are more controversial and could trigger discussions, are especially welcome. For such submissions, criteria pertaining to originality and sound argumentation will be given greater weight during the review process.

Accepted papers will be included in the ACSOS’2021 Companion Volume published by IEEE Computer Society Press and made available as a part of the IEEE Digital Library. Papers must thus be in the same format as the conference proceedings and may not be more than 6 pages in length.
