What is meant by data in transit?

Data in transit refers to information that is actively moving from one location to another across a network. This can include data being sent from a client to a server, data being transmitted over the internet, or any exchange of information between devices in a network. Understanding this concept is crucial, particularly in the context of cybersecurity, as data in transit is often vulnerable to interception or eavesdropping if not properly secured through encryption or other protective measures.

The focus on data transmission highlights the importance of protecting sensitive information while it is being sent, which is a critical aspect of data security and integrity in modern communication systems. This distinguishes it from other types of data, such as data at rest (data stored in databases) and data being processed (ongoing operations within software applications).
