Beyond Zero Trust: Trust Is a Vulnerability

Mark Campbell
2020 Computer  
Zero trust is a systemic approach to information security that trusts no user, transaction, or network traffic unless verified.  ...  Workers were restricted as to which huts they could enter, what they could access, and identity papers were checked frequently-no one was trusted. 1 Trust is a vulnerability and, like all vulnerabilities  ...  ASA, CARTA, and ZTNA In 2014, Gartner introduced its Adaptive Security Architecture (ASA) and extended it in 2017 with the continuous adaptive risk and trust assessment (CARTA) approach.  ...

2009 Computer  
Although the GIG is a DoD-specific project, many of the trust management problems it exposes also occur naturally in existing and emerging commercial and other public networked computing environments,  ...  Information security is, in principle, guaranteed with separated networks, since there is no network path from the more secure to the less secure network.  ...  In particular, KeyNote has been used as the basis for policy control in network-layer security (IPsec) and to control the interaction between application-and network-layer policies, as in the webserver  ...

A trust management model for Body Sensor Networks

Vinh T. Bui
2011 2011 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks  
A foreseen usage scenario for a BSN is the installation of third-party monitoring applications. Existing applications can also be extended by downloading and installing new components dynamically.  ...  To that end we propose an efficient trust management model and we investigate policies and mechanisms to express and control the data usage.  ...  The author would like to thank to Johan Lukkien, Shudong Chen, and Richard Verhoeven, in developing the presented concepts and for their useful comments in improving the quality of this paper.  ...
