Securely removing sensitive cardholder data can be performed in only a few steps. Many merchants believe that this process is difficult. The normal process consists of identifying card numbers, determining false positives, and eliminating or moving that sensitive information.
However, the possibilty of the data lingering in free hard drive spaces is high. The free space on a hard drive contains deleted files that are yet to be written over and this data can be manipulated by common malware or viruses. Adding a secured deletion procedure makes the card cleansing process more comprehensive. Securely deleting your files will wipe the free space clean and reduce the risk of data breach at your stores.
