Harden networks and remote access

The data traffic in the network should be protected with a firewall. A network firewall of this kind has little to do with the software firewall that Windows already comes with – the latter does not protect the network. A network firewall not only checks incoming data to protect against malware, but also checks outgoing data, thus preventing sensitive data from being stolen. It provides protection against malware and malicious websites. Network protection of this kind also includes measures for devices that are often forgotten, such as network printers. Employees should also be able to access company data as well as applications in the company network, if necessary, at any time. Saving files locally on one's own computer is therefore not useful. In order for files to always be available to all employees, they should be stored either in the cloud or on a separate server that is centrally accessible in the company network.
