One can also opens his/her own hardware repair shops after gaining knowledge and experience. Someone once told me that a company’s network should be assembled with care by a professions in the same fashion a licensed electrician would wire a new home. You wouldn’t hire any guy off the street to wire your home in a manner that’s not up to code. Networks grow and undergo change, but the foundation needs to be build on solid ground by someone who knows what’s she’s doing.
A firewall is a network device or software for controlling network security and access rules. Firewalls are inserted in connections between secure internal networks and potentially insecure external networks such as the Internet. Firewalls are typically configured to reject access requests from unrecognized sources while allowing actions from recognized ones. The vital role firewalls play in network security grows in parallel with the constant increase in cyber attacks. The nodes of a computer network may include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment.
Process Overview
There are older network protocols such as ARCNET, introduced in 1977, LocalTalk or Token Ring, but today, most network cards use Ethernet. Such functions together with others such as access management, logging, and analytic tools constitute a solid foundation for implementing security policies and operating the network securely.
A roles and rights system is required to establish individual alert management. It needs a broad range of alerting methods like SMS or push notifications to reach people away from their desk. Finally, triggering an action to automatically solve issues is often a must. Most IT monitoring tools only “speak IT”, means they only support classic IT protocols like Ping, SNMP, Flow, Sniffing and so on. For bringing together IT and OT they must at least have an API and support protocols like JSON or MQTT or standards like OPC UA and Modbus TCP.

You need to know your hardware address in order to register your device in the Princeton University Host Database. The standards and technology just discussed will help define the specific products that network managers use to build Ethernet networks. The following presents the key products needed to build an Ethernet LAN. Using switching and routing technologies, this layer is responsible for creating virtual circuits to transmit information from node to node. Other functions include routing, forwarding, addressing, internet working, error and congestion control, and packet sequencing.
