Chief executives need to "lean in and educate themselves" about cybersecurity, and their businesses should conduct consistent stress testing and drills, one expert says.
Jacqui Kernot, the security director of Accenture ANZ, told AAP that CEOs feel "disempowered" when it comes to cybersecurity in the wake of numerous hacks in the past few years.
"It's just one of these things, you know you're going to get broken into, you don't really know when, you don't really know how, and don't really have any level of control over it," Ms Kernot said.
