Principle of least privilege
example windows solution device drivers run directly installation device drivers must installed separately using windows installer service order grant driver elevated privileges.in practice exist multiple competing definitions true least privilege.program complexity increases rapidly number potential issues rendering predictive approach impractical.examples include values variables may process addresses need precise time things required.object capability systems allow instance deferring granting singleuse privilege time used.currently closest practical approach eliminate privileges manually evaluated unnecessary.
