AusCERT Week in Review for 28th May 2021

Greetings,

To kick things off, in conjunction with National Reconciliation week 2021, AusCERT would like to take this opportunity to acknowledge the First Nations people as the Traditional Owners of the land on which we are on today. We acknowledge all Elders past, present and emerging. The theme this year is “More than a word. Reconciliation takes action.” To find out more about the week and what it means to our First Nations people, please visit the NRW website here.

Our team issued an alert re: VMWare earlier this week, be sure to catch up on it below.

For those of you keen to check out photos from the recent AusCERT2021 conference, we've uploaded several albums to the AusCERT Facebook page.

We’re also pleased to announce that our podcast series “Share today, save tomorrow” is now listed on Spotify. Episode 2 will be released in mid-June.

Last but not least, sharing a special request from our colleagues at UQ Cyber one final time. See below:

Keen on helping the future generation of cyber and information security professionals? Here's your chance!

"Vignette Survey on Effectiveness of Place Managers in Preventing Ransomware"

Folks from UQ Cyber are seeking assistance from the AusCERT membership audience to participate in a cyber security survey that is investigating factors which can influence the effectiveness of cyber security professionals in preventing cyber security incidents such as ransomware within their respective organisations. The survey results will shed valuable insights and influence how organisations should channel their limited resources in preventing cyber security incidents more effectively.

The survey will take approximately 20 minutes to complete. To participate, please click here. Surveys close on Monday 31 May.

For further information, please feel free to get in touch with Heemeng Ho, the lead researcher of this project.

Until next week everyone, have a great weekend.
