Which option is NOT typically considered a method of safeguarding sensitive information?

Open source coding is not typically considered a method for safeguarding sensitive information because it refers to the practice of making source code available for anyone to view, modify, and distribute. While open source software can be secure if properly managed, the act of making the code open does not inherently protect sensitive information. Instead, it invites scrutiny and potential vulnerabilities if the code isn't maintained correctly or audited for security flaws.

In contrast, data encryption is a widely accepted practice for protecting sensitive information by converting data into a format that cannot be easily understood without the appropriate decryption key. Regular backups secure data by creating copies that can be restored in the event of loss or corruption, ensuring data integrity and availability. Access control policies safeguard sensitive information by defining who can access certain data and under what conditions, thereby reducing the risk of unauthorized access.
