I am designing a GUI for a project at my college. I have been told to look at security issues. As the project is not web-based, I don't really know what security issues there would be. The GUI will interface with databases using JDBC, so maybe that's where security will come into play. Advice anyone?
That's where I'd start. Might also look at how you can prevent malicious Java code from intercepting this. For example, how might I use Java to intercept the password when they login and spit it out to a logfile or e-mail it to someone? What about database security and ensuring users can't do anything destructive? It's hard to say what your professor meant by "security". I would start with Stefan's suggestion of at least making them logon to the database themselves and then look at how to protect that information from being intercepted or misused.
