In today’s interconnected and technology reliant world, the expectation of trust and need to trust is growing. Today’s trust-based solutions may become non-viable in the future. As use of the cloud grows, we are experiencing a shift in resource allocation from on-premise to off-premise systems. As systems move to cloud-hosted environments, the loss of control over the access network becomes a concern. Today’s trust-based solutions typically start at the network level. If a user has access to a network, they are typically trusted to have access to some or all of the resources, data, and systems on that network.

But, when networks are unknown and untrusted, how is trust acquired? Zero Trust architectures seek to provide access control techniques that assume the network is not trustworthy. One of the approaches suggested by industry is the use of trust scores. Like a credit score, a cyber trust score could be used to assess the risk potential associated with allowing any given user access to systems and information. But how would a trust score be calculated? Current approaches smack of a violation of privacy where the right to gain access is issued only by agreeing to be monitored.

This paper addresses the technical, social, policy, and regulatory issues associated with creating trust frameworks in a Zero Trust world. Industry and government are called to solve issues in ways that continue to protect the right to a users’ privacy.
