SSD Data Sanitation in Linux

Previously I talked about data sanitation on magnetic media (see my DoD tutorial). Now I want to explore the same topic, only with solid state drives. Data sanitation for SSDs is very different from data sanitation for HDDs - it is both easier and harder. Easier because there's no residual data left over - once … Continue reading SSD Data Sanitation in Linux

Implementing the DoD Data Sanitation Algorithm in C

Most cyber security buffs are familiar with the Gutmann secure erase algorithm - a 35-pass wiping algorithm designed to completely obliterate sensitive information stored on a magnetic medium. The rationale behind this algorithm is that simply erasing a file and overwriting it with zeros is not enough to completely destroy its contents. Since the position … Continue reading Implementing the DoD Data Sanitation Algorithm in C
