What is cyber security

‘Cyber security’ refers to the methods, systems, and tools used to protect people and organisations from the harmful effects of online threats like cybercrime.

Cyber threats and crime are on the rise globally. They can affect any business, industry or person and are becoming increasingly sophisticated and disruptive.

Cyber security versus cyber safety

Cyber security mainly focuses on protecting information and digital systems from online attacks. Cyber safety is focused on protecting people from online abuse.

The eSafety Commissioner has information and resources to keep you safe online.
