Procedures and Methodology

Liam, a cybersecurity specialist, has been tasked with sanitizing several hard drives that formerly contained sensitive corporate data. To ensure no residual data remains on the drives, Liam must follow a particular media-sanitization standard. He needs a wiping method that writes zeros during the first pass and random bytes during the next pass, providing the highest level of data destruction with minimal verification. Which of the following media-sanitization standards should Liam use to satisfy this requirement?

  • A (American) NAVSO P-5233-26 (MFM) (3 passes)
  • B (American) NAVSO P-5239-26 (RLL) (3 passes)
  • C (German) VSITR (7 passes)
  • D (Russian) GOST R P50739-95 (2 passes)
Explanation

GOST R P50739-95 is commonly implemented as a two-pass overwrite method: it writes 0x00 across each sector and then overwrites it with a random value. This matches the required zero-first, random-second sequence without the additional overwrite passes used by the NAVSO and VSITR methods.
