What is the difference between data encryption and data sanitization?

Data encryption is the process of converting data into a coded format to prevent unauthorized access, while data sanitization involves removing sensitive data from a database or system to protect it from exposure.

Can you give me examples of when to use each?

Sure! Use data encryption when transmitting sensitive information over the internet, like credit card details. Use data sanitization when disposing of old hardware or databases to ensure no sensitive information can be recovered.

Are there any risks associated with these processes?

Yes, if encryption keys are lost, encrypted data can become inaccessible. For sanitization, if not done properly, sensitive data may still be recoverable.

How can I ensure my data is properly sanitized?

You can use certified data destruction services or software that complies with standards like NIST or DoD to ensure proper sanitization.
