You could have your switchport just shutdown if it sees more than one MAC, for instance:
interface FastEthernet0/2
switchport mode access
switchport port-security
switchport port-security violation shutdown
spanning-tree portfast
spanning-tree bpduguard enable
And for good measure, the end makes sure that if there is any STP traffic, it blocks it as well.
