    Is there a way to secure a port down to a single MAC address? This is
    on a Catalyst 4006 with IOS 11.

    There are other means, such as dot1x and vpms. But, this is the
    simple/quick way to do it.

    interface FastEthernet0/1
    switchport mode access
    switchport port-security
    switchport port-security maximum 1
    switchport port-security mac-address xxxx.xxxx.xxxx
    spanning-tree portfast

    There are different options on what to do if an illegal address comes in the
    port than what you have listed.
