A zero trust architecture (ZTA) is an enterprise's cyber security plan that utilizes zero trust concepts and encompasses component relationships, workflow planning, and access policies. Therefore, a zero trust enterprise is the network infrastructure (physical and virtual) and operational policies that are in place for an enterprise as a ...
Google documented its Zero Trust journey from 2014 to 2018 through a series of articles in the journal ;login:. Google called their ZT network, BeyondCorp. Google implemented a Zero Trust architecture on a large scale, and relied on user and device credentials, regardless of location. Data was encrypted and protected from managed devices.
The data is used to establish a comprehensive audit of all network traffic, as described in the Zero trust security model, which was initially described in the Red Book, US DoD NCSC-TG-005, [3] supplementing traditional Intrusion detection system (IDS) based network security.
DoD Architecture Framework v1.5. [1] DoDAF Architecture Framework Version 2.0 [2]. The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense (DoD) that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views.
A complete set of the US DoD Rainbow Series computer security documents. The Rainbow Series (sometimes known as the Rainbow Books) is a series of computer security standards and guidelines published by the United States government in the 1980s and 1990s.
The TCSEC defines four divisions: D, C, B, and A, where division A has the highest security. Each division represents a significant difference in the trust an individual or organization can place on the evaluated system. Additionally divisions C, B and A are broken into a series of hierarchical subdivisions called classes: C1, C2, B1, B2, B3 ...
The Bell–LaPadula model (BLP) is a state-machine model used for enforcing access control in government and military applications. [1] It was developed by David Elliott Bell, [2] and Leonard J. LaPadula, subsequent to strong guidance from Roger R. Schell, to formalize the U.S. Department of Defense (DoD) multilevel security (MLS) policy.
Multiple Independent Levels of Security/Safety (MILS) is a high-assurance security architecture based on the concepts of separation [1] and controlled information flow. It is implemented by separation mechanisms that support both untrusted and trustworthy components; ensuring that the total security solution is non-bypassable, evaluatable, always invoked, and tamperproof.
