In the document I found a paragraph:
"Sanitization refers to a process that renders access to target data on
the media infeasible for a given level of effort."

I think the key here is "for a given level of effort" In a PC the "del"
will just mark the file as Reusable, and a very easy process can
undelete the file. Like a record deleted in a file. But if you delete
the object, you will need a very high level of effort to recover it.

DOD publications point to NIST Special Publication 800-88:

The premise is that simply removing all file references (DLTLIB, DEL, etc.)
is inadequate. The DOD called for filling the "disk" with 1's and 0's,
which would probably not be the current terminology.

From what I gather, you use a utility which purges all files, then writes
perhaps many more files to fill up "every sector". Repeat the process 3
times, then do a final purge.

'zactly. It doesn't matter that it would be impossible to get the data
back
without a fabnabulously large amount of work and at an extreme cost. If you
can't prove it's impossible, it's possible.

Darryl,

John Lennon once said "Perception is 99% of reality". Arguing whether
or not SLS scrambles the data around enough after deleting the network
storage space is effective enough, or even better, will get no where
with someone who wants to be able to tell his auditors that "yes, the
data wipe met DoD specifications".
