Word of the Day: gateway

Word of the Day Daily updates on the latest technology terms |April 17, 2017

gateway A gateway is a network node that connects two networks using different protocols together. While a bridge is used to join two similar types of networks, a gateway is used to join two dissimilar networks. The most common gateway is a router that connects a home or enterprise network to the internet. In most IP-based networks, the only traffic that doesn't go through at least one gateway is traffic flowing among nodes on the same local area network (LAN) segment -- for example, computers connected to the same switch. Gateways can take several forms and perform a variety of tasks. These include:   Web application firewall - filters traffic to and from a web server and look at application-layer data. Cloud gateway - provides basic protocol translation and simple connectivity to allow the incompatible technologies to communicate transparently.   API, SOA or XML gateway - manages traffic flowing into and out of a service, microservices-oriented architecture or an XML-based web service.   IoT gateway - aggregates sensor data, translates between sensor protocols, processes sensor data before sending it onward and more.   Cloud storage gateway - translates storage requests with various cloud storage service API calls.   Media gateway - converts data from the format required for one type of network to the format required for another. Amazon API Gateway - allows a developer to connect non-AWS applications to AWS back-end resources.   VoIP trunk gateway - facilitates the use of plain old telephone service (POTS) equipment, such as landline phones and fax machines, with a voice over IP (VoIP) network. Email security gateway - prevents the transmission of emails that break company policy or will transfer information with malicious intent.

Five criteria for selecting an email security gateway product Expert Karen Scarfone explains how organizations can evaluate enterprise email security gateway products to determine which one is the best fit. Using an IoT gateway to connect the "Things" to the cloud An IoT gateway plays a critical role in connecting Internet of Things devices with the Internet, acting as a bridge between the two. Your device is insecure. Use a gateway. We must have a plan B for when security breaks down. Approaching IoT as an architecture in which devices are protected behind a gateway is a good start.
