Modify UNLINK system call so that it is a WIPE and then UNLINK?
Closed source applications used on our server use the unlink system call to delete files.
My goal is to make it so unlink system call actually shreds/wipes the file a set number of times before it returns area to the filesystem.
How would you approach this task?
Thanks for your suggestions!
PS I think this is security and also an OS question, I'll start a thread linking to this one in other areas of the forum hoping this is not against any rule, so any input by other users would remain in one thread.
