Canberra's economy is driven by federal government, defence, intelligence, and higher education, all of which face significant cyber risk. Regulated sectors — particularly those subject to the ISM, PSPF, IRAP, and ASD Essential Eight — have the most pressing compliance-driven requirements.
What is network segmentation and why does it matter?
Network segmentation divides your network into isolated zones so that a breach in one area can't spread freely. It's a critical control for limiting lateral movement — the technique attackers use to move from an initial foothold to your most valuable systems. Essential Eight Maturity Level 3 requires robust segmentation.
Do we need a SIEM if we already have a firewall?
Yes. A firewall is a preventative control; a SIEM is a detective control. Firewalls block known-bad traffic; a SIEM correlates logs from across your environment to detect anomalies that individual tools miss. They serve complementary purposes.
