An application-level gateway ( ALG, also known as application-layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network. [ 1][ 2] It allows customized NAT traversal filters to be plugged into the gateway to support address and port ...
A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks [ 1][ 2] and can operate at any of the seven layers of the ...
t. e. In computing, Internet Protocol Security ( IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs).
Access Point Name. An Access Point Name ( APN) is the name of a gateway [ 1] between a mobile network ( GSM, GPRS, 3G, 4G and 5G) and another computer network, frequently the public Internet. [ 2] A mobile device making a data connection must be configured with an APN to present to the carrier. The carrier will then examine this identifier to ...
Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both ...
Unidirectional network. A unidirectional network (also referred to as a unidirectional gateway or data diode) is a network appliance or device that allows data to travel in only one direction. Data diodes can be found most commonly in high security environments, such as defense, where they serve as connections between two or more networks of ...
A routing protocol specifies how routers communicate with each other to distribute information that enables them to select paths between nodes on a computer network. Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their ...
An interior gateway protocol is a type of routing protocol that operates within an autonomous system or a single network domain. It is used to exchange routing information among routers and to determine the best paths to reach different destinations. This article explains the main features, types and examples of interior gateway protocols, as well as their advantages and disadvantages.
