The cybersecurity sector’s trial by fire
Australian organisations have been hit before, but not like this. Through October and November 2022, breaches at telecoms, health insurers, energy suppliers, online retailers and real-estate agents have exposed the data of millions, leaving many CISOs scrambling for answers.
Worse, these breaches are not an aberration, but part of an upward trend in security incidents. The Australian Cyber Security Centre (ACSC)’s 2022 report shows the number of attacks rising 13% over the last 12 months – and they rose by around the same volume the year before too.
According to Mimecast’s State of Email Security Report 2022, Australia saw a higher than average increase across all email-related attacks, with 77% of companies surveyed hurt by a ransomware attack, up from 64% the previous year.
Findings from Mimecast’s State of Ransomware Readiness Report 2022 revealed that 20% of surveyed Australian organisations had sustained 6 or more ransomware attacks in the past year – higher than any other country surveyed.
The response to this wave of breaches will be crucial for Australia’s cyber future. As the government considers its response, what should individual CISOs and CIOs do next? There are obvious questions here for senior security leaders:
What just happened, and why?
How do I talk to my board about it?
How can we respond if we are breached?
How can we manage risk better in the future?
With insider advice from fellow CISOs on Mimecast’s Customer Advisory Board, we explore the factors that led to the latest breaches, a CISO’s duty of care and best practice in incident response and attack surface management. There are many lessons to learn from these attacks – and even some grounds for optimism.
