Is an e-mail which is deleted still recoverable with the proper utility? If so, how can they be deleted permanently?
Now, within Windows itself, there are numerous tricks and tweaks that one can perform to
increase data security:
- Configure the NT/2000 pagefile.sys file to clear itself upon system shutdown. More useful in a workstation than a server, since servers tend not to be shut down as often. See MS KB article # Q182086.
- Configure the Windows Recycle Bin so that deleted files are not sent to the Recycle Bin, but are rather permanently deleted right away. Also configure any Outlook/Outlook Express/etc. Deleted Items folders to empty upon shutdown.
- Ensure that any print spoolers are not configured to retain printed documents in memory unless your print environment absolutely necessitates it.
- Perform regular disk maintenance: clean out Temporary Internet Files folders, clear your IE cache, defrag (if applicable), and so on.
Hope this provides a good starting point in your quest for data security.
