Some have argued that Unix/Linux systems reuse a small number of security features in many contexts across the system; while Windows systems provide a much larger number of more specifically targeted security features used in the appropriate contexts. This may be seen as a trade-off between simplicity verses lack of flexibility in the Unix/Linux approach against a better targeted but more complex and harder to correctly configure approach in Windows. Discuss this trade-off as it impacts on the security of these respective systems, and the load placed on administrators in managing their security.
