Security Java Prevent Memory Track/Sniff
Posted on 2009-05-07
We handle credit cards on Windows desktop (Not Web).
I need to know if there is a way to prevent hackers from tracking or sniffing the memory of our program to steal card numbers.
We obfuscate the jar of our application and create and executable to execute 3 applications (classes with main method) in the jar, which are the only ones that are not obfuscated. Does signing add to our security?
I'm aware of sniffers that install in a PC and steal things like passwords and credit cards. I doubt there is much I can do about that (but if there is I'd like to hear about it!)
So, my question is restricted to Java security, but I'd certainly entertain paying for extra information on how to increase security in general.
