Abstract: A computer implemented security system (10) and method are disclosed. A user interface (20) is displayed on a display device (30), the user interface including a positioning guide (100) and a marker. User inputs are received on a password comprising a plurality of symbols and a location for each symbol in the user interface (20) relative to said positioning guide (100). Authentication is performed in dependence on the received user inputs and on the marker, the marker being selected from a plurality of markers, each marker designating a different condition to be met by the received user inputs to be successfully authenticated.

Abstract: A secure access system, method and patch management system for access to a remote computer system is disclosed. The remote computer system requires local authentication to boot an operating system. A client module is arranged to be executed on the remote computer system upon booting of the computer system and is arranged upon execution to obtain access data over a network from an authentication system for access to the computer system and to use said access data to perform said local authentication at the remote computer system and boot said operating system. The authentication system being arranged to said store access data for the remote computer system in a data repository and being responsive to provide said access data to said client module over the network upon authentication of a request from the client module.
