Product Description

Innovation Data Processing's FDERASE for z/OS Version 5.4, Level 50 provides security functions related to the secure erasure of data on disk for the IBM mainframe platform running the z/OS Operating System.

Specifically, the Target of Evaluation supports two grades of secure erasure:

1.  “ERASE”: overwrites every track of the disk record with a track-length record, consisting of binary zeroes by default.
2.  “SECURE ERASE”: the data to be erased is overwritten at least three times; with a random pattern, its binary complement, and a different random pattern.

In addition, there is a “VERIFY” function, which samples bits on the Direct Access Storage Device(DASD) to ensure that the data has in fact been overwritten.
