Hi,
I was wondering whether anyone knew of packages/tools to aid in "sanitizing" a
FreeBSD system, i.e., wiping
+ the swap partition
+ non-allocated space on volumes
+ "file-tails" (the part of the last block not used)
with random patterns to avoid leakage of sensitive information (plain text
keys or decrypted texts).
I'm also interested in people's personal experiences in using partition or
file system encryption options.
With many thanks for your help,
David.
PS: Thanks, Roman, for pointing out the need for a Subject line! :)
