Secure erasure refers to the process of permanently deleting data from storage devices so that it cannot be recovered. This is important for protecting sensitive information, such as personal data or confidential business files. Techniques for secure erasure include overwriting data multiple times or using specialized software designed to ensure that the original data is irretrievable. Methods of secure erasure can vary depending on the type of storage media, such as hard drives, solid-state drives, or USB flash drives. Organizations often implement secure erasure practices to comply with data protection regulations and to safeguard against data breaches.
