CompTIA's Security+ without a doubt. If you pass that wth flying colors, then you will know that you are ready to move on to either more technical certs or more managerial certs.
Either way, as far as entry-level security certs, this is my pick. A close second may be
SANS GIAC Security Essentials.
Hope this helps,
