Platform and Infrastructure

  • NIST purge method for media sanitization (QFX5130-32CD, QFX5130-48CM, QFX5220, and QFX5230-64CD)—We've extended support for NIST media sanitization for SATA hard disk drives to include:

    • Cryptographic scramble and block erase priorities for the purge method.

    • Enhanced secure erase priority for the clear method.

    For example, you can use this high level of data destruction when you pull a device from production. To maintain data security, sanitize any disk drives in the device before they leave your premises. The NIST Special Publication 800-88 specifies the priority levels for sanitizing disk drives. In Junos OS Evolved, sanitize a disk drive using the request system zeroize (disk1 | disk2) command. The sanitization process starts at the highest NIST sanitization priority that the disk drive supports. If the attempt fails, the process uses the method associated with the next lowest NIST priority level, and so on, until the disk is sanitized either using one of the NIST methods or using the Linux dd command.
