Remove all administration accounts from systems
Implement privilege management mechanisms that link the admin user to an individual
Ensure that admin access to systems is performed from dedicated hosts with no or very strictly controlled external access
Review all privilege accounts on a regular basis
The primary goal of controlling administrative access is to know who did what, when they did it and that they are authorized to do so. Removing admin accounts is not a viable option, since in some cases they are required to perform actions on systems. Enforcing two person integrity is not an option since it increases the overall cost of administration. There may be some edge cases in highly sensitive environments where this would be applicable, but as a rule it is not feasible for ALL administrative access. Administrators should use dedicated terminals, have account permissions reviewed on a regular basis and all admin actions need to traceable to the actual user, not a group account or 'root'.
