I've been working in and around network security a few years now and I'm thinking about sitting the CISSP exam. My biggest question is 'is it worth it'? Its not a cheap test, and the test prep won't be without a degree of cost as well. The key thing here is that I'm not calling out to those that got the cert because they were otherwise barred from a particular position. I'm speaking to those that are already on the job and who went out and got the cert. Bottom line, how much, if any, did your salary increase once you passed the exam?
