Recommendations

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Allow only trusted and accountable individuals to have local interactive access to vulnerable computers.

Implement multiple redundant layers of security.
As an added precaution, deploy memory-protection schemes (such as nonexecutable stack/heap configuration and randomly mapped memory segments). This may complicate exploits of memory-corruption vulnerabilities.
