+secure-delete for Debian
|
||||||
|
+------------------------
|
||||||
|
+
|
||||||
|
+The original package and debian versions prio to 3.1-5 contained a utility
|
||||||
|
+called smem that wiped memory. This utility seems to be of limited use and
|
||||||
|
+clashes with another binary of the same name, it is therefore renamed to sdmem.
|
||||||
|
+
|
||||||
|
+The source for secure_delete contains a 2.4 kernel module that turns every
|
||||||
|
+call to unlink() into a secure remove, this module is not yet part of this
|
||||||
|
+package for technical reasons. if you need it please "apt_get source
|
||||||
|
+secure-delete" and build it yourself for now.
|
||||||
|
+
|
||||||
|
+Also note that securely wiping data from magnetic media is a difficult task and
|
||||||
|
+depends a lot on the filesystem in question (among other things). So there is no
|
||||||
|
+guarantee that this program will work in your configuration, but you can and
|
||||||
|
+should check for yourself by creating a loopback filesystem, mountig it and
|
||||||
|
+creating a file in it, then securely wiping it and grepping for it's contents in
|
||||||
|
+the loopback file:
|
||||||
|
+
|
||||||
|
+dd if=/dev/zero of=disk bs=4096 count=1024
|
||||||
|
+mke2fs disk
|
||||||
|
+losetup /dev/loop0 disk
|
||||||
|
+mkdir test
|
||||||
|
+mount /dev/loop0 test
|
||||||
|
+cd test
|
||||||
|
+for ((i=0; i<10000; i++))
|
||||||
|
+do
|
||||||
|
+ echo "ofenrohr" >> file;
|
||||||
|
+done
|
||||||
|
+cd ..
|
||||||
|
+umount test
|
||||||
|
+losetup -d /dev/loop0
|
||||||
|
+grep "ofenrohr" disk
|
||||||
|
+--> this should result in a "binary file disk matches"
|
||||||
|
+losetup /dev/loop0 disk
|
||||||
|
+mount /dev/loop0 test
|
||||||
|
+cd test
|
||||||
|
+srm file
|
||||||
|
+cd ..
|
||||||
|
+umount test
|
||||||
|
+losetup -d /dev/loop0
|
||||||
|
+grep "ofenrohr" disk
|
||||||
|
+--> this should not find anything
|
||||||
|
+
|
||||||
|
+Please make sure you use the correct filesystem type and options during the
|
||||||
|
+mkfs!
|
||||||
|
+
|
||||||
|
+Another general problem of wiping data from disks is that most harddisks will
|
||||||
|
+occasionally mark a sector as "bad" and copy it's contents to a new location
|
||||||
|
+that the disk will pretend is at the original location. Since this is completely
|
||||||
|
+transparent, there is no way to access these sectors without touching the disks
|
||||||
|
+hardware. These sectors may then contain sensitive information that could be
|
||||||
|
+retrieved from the disk. If you want better security, use an encrypting
|
||||||
|
+filesystem (dm-crypt, loop-aes), and forget the key if you want to wipe it.
