The kernel variable, randomize_va_space is accessible through a pseudo file of the same name.

It is located in the proc file system at:

        /proc/sys/kernel/randomize_va_space
     

Listing this "file" shows:

• the owner is root
• root has rw (read/write) permission
• others have only r (read) permission
• the "file" has 0 bytes (not really, it isn't really a file)
