CERT Australia's report found that 56 per cent of the businesses surveyed had identified intrusions or incidents on their networks. This was an increase of 34 per cent on the 2012 findings where 22 per cent of respondents had found cyber security incidents.
Most of these incidents were targeted emails, followed by virus/ worm infection and Trojan or rootkit malware.
While cyber intrusion incidents were on the rise, the number of businesses that spent more on IT security had decreased by 25 per cent since the 2012 report.
According to CERT Australia, only 27 per cent of businesses surveyed spent more on IT security in 2013, compared with 52 per cent of businesses in 2012.
Brandis also had some cyber security advice for Australian businesses:
- Understand the value of your information and how it is protected on your network
- Create a culture of cyber security awareness and practices
- Ensure cyber security incidents are identified in your business risk register.
