Data fragmentation is the process of dividing data into smaller pieces, or fragments, and storing them in different physical or logical locations. This approach enhances security by making it harder for unauthorized parties to access or reconstruct the complete dataset if one fragment is compromised. Data fragmentation is commonly used in cybersecurity to protect sensitive information, reduce the risk of data breaches, and improve data management. It can also help with performance optimization and compliance with data protection regulations by ensuring that data is not stored in a single, vulnerable location.
