The following is a conceptual question -- as opposed to a specific technical issue/bug. I will award points to the most helpful answer within the next 48hrs.
Situation: I run a laptop with Suse 10.1. I store sensitive data on the machine in a specific directory and in a MYSQL database. I feel confident that the system is secure enough from a software perspective. However, I am worried that I might lose the laptop or that somebody could steal it from my office at night.
I think the best way to guard against exposing this data through physical loss of the machine would be to use encryption.
Do you have any elegant solutions for doing this? Is there a way to use PGP or some other software to encrypt certain data each time the machine shuts down and descrypt it upon booting up? Again, the data reside in a specific directory and a MYSQL database.
Thank you in advance for any help!
