Additionally, the 2022 Data Breach Investigations Report (DBIR) found that 82% of breaches involved the human element, including social attacks, errors, and misuse.

Factors Contributing to Human Error in Cyber Security

Lack of Training and Awareness

Human error has a well-documented history of causing data breaches. Sometimes personnel may take cybersecurity requirements too lightly, leading to dramatic consequences for the organizations they work for. Careless or uninformed staff, for example, are the second most likely cause of a serious security breach, second only to malware.

Complexity of Security Systems

The breakdown of cyber incidents was ransomware – 29%, compromised or stolen credentials (method unknown) – 27%, phishing (compromised credentials) – 23%, brute-force attack (compromised credentials) – 9%, hacking – 8%, malware – 4%. The top causes of human error breaches were:

  • Personal information sent to wrong recipient (email) – 42%

  • Unauthorised disclosure (unintended release or publication) – 33%

  • Failure to use BCC when sending email – 6%

Inadequate Policies and Procedures

Former Australian Federal Police officer and cyber security expert Nigel Phair said human error was a very likely contributing factor in the massive data breach. "Organisations like Optus and many others of that ilk have really good controls around firewalls and identification of intrusions and that type of thing," Mr Phair said. "There's been a weakness somewhere and invariably that weakness, from what we've seen normally, is from a human."

Impact of Human Error on Australian Businesses

Human error within a business can have many undesirable effects. Human error almost certainly played a decisive role in the Medibank, Optus, and multitude of other data breaches plaguing Australian companies. This section explores the various impacts of human error on businesses in Australia.

Preventative Measures to Mitigate Human Error

Regular Cybersecurity Training

Regular cybersecurity training is essential to keep employees aware of the latest threats and best practices. Training should be conducted quarterly to ensure that all staff members are up-to-date with the latest security protocols. Key areas to focus on include:
