Definition
Encryption in Transit protects data exchanged between systems against reading or modification by unauthorised parties.
Human Explanation
Data is encrypted while travelling across a network so that others cannot read or alter it.
Why it Matters
It protects the confidentiality and integrity of data sent over public and private networks.
Conceptual Boundary
Encryption in Transit does not protect data stored on devices or servers.
Practical Perspective
Even highly confidential data may be intercepted if it is transmitted without appropriate Encryption.
