Abstract:
1. A secure access system for access to a remote computer system, the remote computer system having a processor and an encrypted storage medium storing an operating system, the processor of the remote computer system being configured to execute computer program code to operate the remote computer in a first mode to require local presentation and authentication of credentials by a user at the remote computer to boot the operating system, wherein the local authentication is performed without reference to a system external to the remote computer and wherein successful local authentication causes the processor to execute computer program code to decrypt the encrypted storage medium to enable booting of the operating system, the secure access system comprising an authentication system and a client module, wherein: upon receiving a boot request over a data communications network, the processor of the remote computer system is configured to execute computer program code to operate the remote computer system in a second mode including executing computer program code to execute the client module upon booting of the computer system, the computer program code being configured upon execution to obtain access data over a network from the authentication system for access to the computer system and to use said access data to perform said local authentication at the remote computer system, cause decryption of the operating 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.
