An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.

Network Enclaves consist of standalone assets that do not interact with other information systems or networks. A major difference between a DMZ or demilitarized zone and a network enclave is a DMZ allows inbound and outbound traffic access, where firewall boundaries are traversed. In an enclave, firewall boundaries are not traversed.
Operations, administration, and management or operations, administration, and maintenance (OA&M or OAM) are the processes, activities, tools, and standards involved with operating, administering, managing and maintaining any system. This commonly applies to telecommunication, computer networks, and computer hardware.
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
Computer network operations (CNO) is a broad term that has both military and civilian application.Conventional wisdom is that information is power, and more and more of the information necessary to make decisions is digitized and conveyed over an ever-expanding network of computers and other electronic devices.
IP address management (IPAM) is a methodology implemented in computer software for planning and managing the assignment and use of IP addresses and closely related resources of a computer network. It does not typically provide Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) services, but manages information for these ...
For example, compartment boundaries can be defined by a certain type of network technology (e.g., a specific wireless access network) or based on a particular communication protocol and/or addressing space (e.g., an IPv4 or and IPv6 network), but also based on a policy domain (e.g., a national health network that requires a highly secure boundary).
In network security, evasion is bypassing an information security defense in order to deliver an exploit, attack, or other form of malware to a target network or system, without detection. Evasions are typically used to counter network-based intrusion detection and prevention systems (IPS, IDS) but can also be used to by-pass firewalls and ...
