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 ...
A network security policy (NSP) is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security/ network security environment. [1] The document itself is usually several pages long and written by a committee.
Software-defined protection (SDP) is a computer network security architecture and methodology that combines network security devices and defensive protections which leverage both internal and external intelligence sources. [1] An SDP [2] infrastructure is designed to be modular, scalable, and secure.
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.
Network security are security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network ...

In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on configurable security rules. [ 1 ] [ 2 ] A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet , [ 3 ] or between several VLAN s.
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
