    • According to one aspect of the invention, a hierarchy of security domains and a method for granting a user access to the security domains are provided. The hierarchy of security domains includes multiple security levels and relationships between particular security domains. When a user is authenticated and/or authorized for access to a first security domain, the user is tagged as having been granted access to that security domain. If the user attempts to access a related security domain with a lower security level, the user is granted access without having to be re-authenticated and/or re-authorized. If the user attempts to access a related security domain with a higher security level, the user must be re-authenticated and/or re-authorized be access is granted to the security domain with the higher security level.
    • 根据本发明的一个方面,提供了安全域的层次结构和用于授予用户对安全域的访问的方法。 安全域的层次结构包括多个安全级别和特定安全域之间的关系。 当用户被认证和/或被授权访问第一安全域时,用户被标记为已经被授权对该安全域的访问。 如果用户尝试访问安全级别较低的相关安全域,则无需经过重新身份验证和/或重新授权即可授予用户访问权限。 如果用户尝试访问具有较高安全级别的相关安全域,则必须对用户进行重新认证和/或重新授权,才能将访问权限授予具有较高安全级别的安全域。
