Notes on secure virtual memory
Authored by: TrueWhore on May 21, '05 04:07:16AM
Because secure swap is not enabled by default on a new install you have to be aware of something if you decide to enable it: Any data that was in your memory at any point before you enabled it is quite likely still on your disk. This could include your login password etc.

See http://onebutan.com/Secure_virtual_memory for the procedure to clean your disk.

When I was experimenting with it, another person wrote a perl script to overcommit memory to force swapping, and he noted that there is a performance hit with encryption on. In real world use I haven't found it to be a problem (I have it on).

I have it on too, no performance issues here. I'm a real world user too ;)
