Give atleast 3 solution that you can do about Data Remanence

pleasy help me to answer this. Thankyou

Some of the countermeasures for dealing with the data remanence are: Purging, which involves permanent removal of sensitive information from the memory or storage device. Clearing involves removal of sensitive information from a storage device so that reconstructing the data requires special recovery software or tools. Destruction refers to physically destroying the storage device so that the data cannot be recovered from it. Overwriting, one of the common methods employed to counter data remanence issues involves overwriting data on the storage device several times so that the original data cannot be reconstructed. Degaussing is a technique used for destroying data on magnetic storage tapes. It uses a box-like device known as a degausser which works by changing the magnetic field on the tape, effectively destroying the data on the tape. Degaussing can also be used to erase the contents of a hard drive, USB thumb drive, smartphone, or floppy disk. Storing data on media by encrypting it before storage is an effective countermeasure against data remanence. If the encryption is strong and the encryption keys are kept secret, it is difficult to get unauthorized disclosure of information from the media
