Understanding the risks

The 4 C's of Online Risk

A new classification of online risk – the 4Cs

The 4Cs classification helps to identify aggressive, sexual, and value risks that children may face online. It's important to consider the risks to children's values, privacy, health, and fair treatment. These risks can be related to content, contact, conduct, or contract risks. It's essential to note that online risks to children are complex and can overlap. The classification is a tool to help understand and investigate risks, but it doesn't mean that the risks are straightforward or separate from one another.
