10.7: Disable Secure Virtual Memory
Authored by: Arakageeta on Sep 21, '11 07:57:19PM

This is a terrible idea. Let's just run the command "strings" on your swap space and see what we find. So many programs will store sensitive information (like passwords) in memory in the clear. Watch out if that memory gets swapped to disk and is unencrypted. The attack doesn't even require a user account. You can just remove a hard drive from a system, plug it in another, and do the same thing.

10.7: Disable Secure Virtual Memory
Authored by: Michelasso on Sep 26, '11 02:48:06AM

It is useful for reference. If one ever wonders if the secure virtual memory is enabled here there is the command to check it and in case to re-enable it back.

Some people like to dig into the insides of the OS. With this one can check if the virtual memory on clear really shows the passwords. It is good for research. Why everything has to be a "bad idea"? There is no good or bad, it's just a piece of technical information.
