The scope of administrators’ work therefore includes the appropriate configuration of FireWall and routers, security and configuration of WiFi networks with access points, controllers and encryption protocols.

Network administration Q&A
Network administration – what is it?
In the case of any IT infrastructure, its nervous system is the IT network. It is primarily a series of connections thanks to which computers, printers and all the devices included in it can communicate with each other. Its central center is the server on which, m.in, important data is stored.
Network administration is a series of tasks whose primary purpose is to ensure maximum efficiency of these connection systems. At the same time, it is also necessary to implement security solutions, e.g. against the possibility of leakage of important information.
A good computer network administrator must be responsible for monitoring the computer network and searching for those points in it that may pose a potential security risk. In this way, the risk of major accidents in the future can be eliminated, among other things.
However, in fact, this is only the basis, because network administration is a much broader concept. There are a lot of duties, and their implementation requires not only time, but above all experience and broad, specialist knowledge.
Our company Lizard can take on all these responsibilities. The quality of these services is best demonstrated by the constantly growing trust of customers running their own businesses m.in in Krakow, Poznań, Warsaw or Wrocław. We serve both small companies and large enterprises in which managing a computer network is a unique challenge.
What is the administration of computer networks?
Constantly recurring and often deepening problems with the computer network may negatively affect, for example, the efficiency of data flow, hindering communication with the server. This, in turn, can lead to downtime in the company, problems with the implementation of orders, and even deterioration in the quality of customer service.
What’s more, today a lot of confidential data is stored in a computer network that must be properly secured. IT systems are not only exposed to external attacks. The problem may also be internal – it is enough for the employee to install on his computer software downloaded from an unreliable source.
Professional network administration is not only monitoring and responding to emerging failures. It also means planning the development of infrastructure, both in terms of eliminating current problems and increasing its efficiency and functionality in the future.
