1. A method comprising:
requesting authentication of a user attempting to access a first resource through a session, the first resource being within a first security domain, the first security domain being within a hierarchy of security domains, the hierarchy defining related and unrelated security domains and a relative security level of one or more related security domains;
identifying the session as having access to the first security domain;
granting the user access to a second resource without requesting authentication of the user for access to a second security domain based on said identification, the second resource being within the second security domain, the second security domain related to the first security domain and having a lower relative security level than the first security domain within the hierarchy of security domains; and
not granting the user access to the second resource without requesting authentication of the user for access to the second security domain if the second security domain:
is unrelated to the first security domain, or
is related to the first security domain but has a higher relative security level than first security domain within the hierarchy of security domains.
