JSON (JavaScript Object Notation)

JSON is a simple data format that is used to exchange information between systems.

What does JSON mean in detail?

JSON is an easy-to-understand format in which data is represented in a structured way. It is often used so that programs can exchange information.

The data is stored in the form of “key-value pairs”, for example:

• Name: Max Mustermann
• Role: Employee

JSON is particularly common in web applications and interfaces (APIs).

Where do I come across this issue in my day-to-day work?

• When using web applications
• When exchanging data between programs
• For interfaces between different systems

Practical example:

An online tool transfers data to another system, e.g. from a form to a database. The information is often transferred in JSON format.

What can I do to improve my safety?

1. Only use trusted applications
2. Critically check unknown files or data sources
3. Report anomalies in programs

Note: JSON itself is not a security risk, but can be used by applications that are attacked.
