Data encryption is the process of converting data into a coded format that can only be read by someone with the correct decryption key. This ensures that even if data is intercepted by unauthorized parties, it remains unreadable and secure. 

Encryption is vital for protecting sensitive information both at rest (stored data) and in transit (data being transmitted).

2. Data Masking

Data masking involves obscuring specific data within a database so that unauthorized users cannot see or access it. This process often protects sensitive information such as social security numbers, credit card details, and personal identification information. Masking ensures that data cannot be used maliciously even if it is accessed.

3. Data Erasure

Data erasure, also known as data wiping, is the process of securely deleting data from storage devices so that it cannot be recovered. This is crucial for protecting sensitive information when devices are retired or repurposed. Data erasure ensures that no residual data remains that could be exploited.

4. Data Backup

Data backup involves creating copies of data and storing them in separate locations to protect against data loss. Regular backups are essential for disaster recovery, allowing organizations to restore data in the event of hardware failure, cyber-attacks, or other data loss incidents. 

Effective backup strategies include multiple copies, offsite storage, and regular testing to ensure data can be restored when needed.
