//Week in review - 27 Jan 2023
The latest episode of AusCERT’s Share Today, Save Tomorrow podcast is available for download, featuring Jess Dodson (@girlgerms) chatting with Anthony Caruana about her Zero Trust journey. Frameworks or ideas like Zero Trust often emerge in fast-paced industries like cyber security, however they’re sometimes unfairly overlooked as a “buzz phrase” or “passing trend”. Jess’s excellent presentation at the AusCERT2022 Cyber Security Conference gives a great, no nonsense explanation of what Zero Trust actually is and how you can implement it within your organisation.
Speaking of the AusCERT Cyber Security Conference, the AusCERT2023 Call For Presentations CLOSES this evening! If you haven’t submitted your idea yet there’s still time, and remember we’re very keen to support first time presenters with additional mentoring. Many professionals have imposter syndrome, but remember your experiences are uniquely yours and quite likely very interesting to others! If you’re still stuck for ideas, listen to our joint presentation with Lidia Giuliano (@pink_tangent) and AusCERT's Mark Carey-Smith, Bek Cheb and Mike Holm from Tuesday this week, “How to prepare a speaking topic and submit to a conference CFP”. Some additional resources are available on the Call for Presentations page, such as the padlet coordinated by Mark containing crowd-sourced ideas on “What makes a great conference presentation?”.
In amongst imposter syndrome, too-much-compliance fatigue, not-enough-resources burnout, rising costs and other such worries, it’s easy to lose sight of the real goals of your organisation or business unit. At this time, your professional network and trusted partners can significantly contribute towards your success. Why not discuss cyber security topics with peers on AusCERT’s Member Slack or other communities like the JCSC Slack, use free resources like this blog and AusCERT Daily Intelligence Report to help you keep up to date and plan your year?
Here's the top stories from this week, in case you missed any of them:

IoT vendors faulted for slow progress in setting up vulnerability disclosure programs
Author: The Daily Swig
IoT vendors are making slow progress in making it easy for security researchers to report security bugs, with only 27.1% of suppliers offering a vulnerability disclosure policy.
The figure, based on the latest annual report from the IoT Security Foundation (IoTSF), compares to the 9.7% of IoT (Internet of Things) vendors that were reported to have a disclosure policy in the 2018 edition of the same study.
Vulnerability management ought to be a cornerstone of connected product security, widely recommended in 30 cybersecurity guidance initiatives including the IoTSF’s IoT Security Assurance Framework.
Universities offered software to sniff out ChatGPT-written essays
Author: The Register
Turnitin, best known for its anti-plagiarism software used by tens of thousands of universities and schools around the world, is building a tool to detect text generated by AI.
Large language models have gained traction since the commercial release of OpenAI's GPT-3 in 2020. Now multiple companies have built their own rival machine learning systems, kickstarting a new wave of startups developing products powered by generative AI. These models operate like general-purpose chatbots. Users type instructions, and they will respond with passages of coherent, convincing text.
