Security link management in dynamic networks

A computer-readable medium having computer executable instructions for performing the steps of a method of providing a mobile computing unit with privileged access to a computing resource, the method comprising the steps of:

• denying the mobile computing unit access to the computing resource for failure of a user of the mobile computing unit to complete a log-in to gain unlimited access to the computing resource because the user has not submitted sufficient identifying information;
• obtaining credentials with a unique machine identifier to facilitate authenticating an identity of the mobile computing unit;
• providing the credentials to an authenticator to prove the machine identity, the authenticator controlling access to the computing resource;
• and
• establishing limited access to the computing resource using authorization information obtained from the authenticator to reflect a relative security level for a user of the mobile computing unit, the authorization information corresponding to the authenticated identity of the mobile computing unit.
