Terminology around privacy and security often will use the term “PII” – to refer to “Personally Identifiable Information”. However, PII in Australia is not a valid term – the definition by the OAIC is “personal information”, and it differs from the US term (from NIST) and the legal obligations around… Continue Reading PII in Australia and personal information

I have posted a few articles about different security standards and frameworks, such as PCI-DSS, The Essential 8, ISO27001, NIST and others – and in my experience, there are some organisations that focus on compliance instead of security. People desperately chase the dogma of maturity levels or complying with every… Continue Reading Focus on Compliance or Security?

As the world becomes more aware of cybersecurity risks and issues, company boards need to become more aware of the issues that cybersecurity poses for their businesses.

A question that has been around my mind for a while is “does the CISO need to become the CSO”?

Last month, I wrote an article on the Essential 8. The article pointed out that for most of the measures, they should be the absolute minimum measures that organisations take with their systems. For those who work in the area of security, most of the Essential 8 are common-sense and… Continue Reading Obvious PCI-DSS benefits

The Australian Cyber Security Centre, working alongside the Australian Signals Directorate (formerly Defence Signals Directorate) created a list of eight essential mitigation strategies to act as a baseline for cybersecurity. These are very much basic and essential measures, and they are an absolute minimum. As a cybersecurity professional, these are… Continue Reading What is wrong with the Essential 8?

It is a well-known adage in cybersecurity that there is a balance between usability and security – if you increase the security and control, you decrease usability.
