With the Certified Information Systems Auditor (CISA) already under your belt, your next credential could be the Certified Protection Professional (CPP) but only if you have seven years of security-related work experience to go along with your degree in economics. Check http://www.asisonline.org/cpp.html for more details on this excellent program.
You might also want to consider one or more of the following credentials, all of which will leverage your current experience and your auditing and accounting background:
