User Authentication

A apparatus for providing a user access to a computer system comprising a plurality of services and a plurality of authentication levels, the apparatus comprising:

• a plurality of processors;
• a non-transitory computer readable storage medium coupled to the plurality of processors;
• and
• logic, stored on the computer-readable storage medium and executed on the plurality of processors, for:
• dynamically monitoring a risk profile of a user authenticated on said computer system;
• dynamically selecting an authentication level for each of said services based on said monitored risk profile;
• determining that said authentication level for a service is higher than an actual authentication level for said user;
• and
• in response to the determining, sending a further authentication request to the user requesting the user to provide authentication information corresponding to at least the dynamically selected authentication level upon said authenticated user requesting access to said service.
