Abstract
A computer system is described in which users can access a protected resource only by way of a call to a user monitor command, specifying the protected resource as a parameter. The user monitor command checks that certain conditions are satisfied and performs specified actions before permitting access to the protected resource. The checks may include checking whether options and argument values supplied by the user satisfy specified conditions. The actions may include dynamically modifying a supplementary groups list of a current process temporarily granting or removing privileges to or from the user.
