The security module is organised to allow a single operator (the security supervisor) accesses to all Atos products and associated On-line transactions. In the security module, the security supervisor is the chief operator overseeing all activity within all systems. The security supervisor can set the parameters for any number of supervisors. A supervisor can then set parameters for their sign-ons, but cannot use parameters outside of their own. A security supervisor can override any parameters set by the supervisors (refer to the chart below).
