Now that I've been working in I.T. for almost 2 years now as a Technology Support Specialist/ Network Analyst and I have my Bachelors in I.T. Management, I've found that I am very interested in security. I really would like to get a job in security, but I found out to even qualify to sit for the CISSP exam, I need at least 5 years of security experience or 4 years with a 4-year degree; I have the degree, but not the experience.

And I also need a sponsor that already has a CISSP, and I know of no one with a CISSP

How do I go about preparing myself to get my foot in the security door?.. if I were to apply for entry-level security jobs will I be required to have a security certification?... I'm curious. Thanks for any feedback.
