Data protection techniques are methods used to safeguard sensitive information from unauthorized access and breaches. These techniques include encryption, which scrambles data so that only authorized users can read it, and access controls, which limit who can view or modify data. Regular backups are also essential, ensuring that data can be restored in case of loss or corruption. Another important technique is data masking, which hides specific data within a database to protect it while still allowing for analysis. Additionally, using firewalls and antivirus software helps defend against cyber threats. Together, these methods create a robust framework for protecting valuable information.
