Someone takes your log file, data file or back up file and take it any where so in order to make it safe we do Transparent Data Encryption.

Transparent Data Encryption (TDE) encrypts SQL Server data and log files. It performs real-time I/O encryption and decryption of the data and log files. It uses a database encryption key (DEK), which is stored in the database boot record for availability during recovery.

You can check your files @ depending on the version-

C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA
C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log
