Week in review
Greetings,
The AUSCERT team are excited to announce that the Call for Presentations and Sponsorship options for next year’s conference are open!
We believe that there is an abundance of potential speakers from far afield and close to home, even if people don’t know it. To help those unsure of what to speak about or, in need of some assistance, AUSCERT has implemented some new initiatives aimed at helping uncover talking points and help interested parties develop their presentation.
These include a mentorship program and a webinar titled, “I don’t have anything to talk about”, scheduled for early 2023.
If you would like some inspiration or ideas, perhaps an episode of our podcast, ‘Share Today, Save Tomorrow’ is in order. This includes our last episode of 2022 , released today, that features Dave Lewis, a speaker at this year’s conference and is currently a Global Advisory CISO for Cisco. Dave is also working towards his graduate degree at Harvard and wrote columns for Forbes, CSO Online, Huffington Post, The Daily Swig and others.
If you’re considering sponsorship at AUSCERT2023, we have the usual offerings along with some returning favourites from this year – including the Gelato Cart – along with some fantastic new options that we think will be highly sought after! If you’d like to see what’s on offer, simply visit the sponsorship portal and request a copy of the Sponsorship Prospectus.
With just over a week until Christmas Day, many people have placed online orders for their gifts and no doubt are anticipating the delivery each day. If you are one of the many on the look-out for a delivery, beware of potential scams that make claims of a failed delivery, requesting you update your details – be warned, DO NOT click on any links!
This is just one of the ’12 Scams of Christmas’ that have been compiled to promote awareness and hopefully, keep everyone safe this Festive Season!
