The networks have never been under so much pressure, they must support large groups of people who work from anywhere (home, office, remote locations) and use different computers and communication devices and connect to corporate systems in different ways . We must not forget the large increase in IoT devices appearing in the network, which can easily pose additional security threats. However, all users have the same needs – they must be connected and secure in the network. If the situation becomes too complicated, it often leads to errors and unpredictable problems.
It is very difficult to maintain heterogeneous networks, which do not have common tools and operate according to different principles. Such networks cannot be easily integrated and connected. The operational teams, who deal with the management of such networks, have to rely on a large amount of manual work, which opens space for the relaxation of regular maintenance and security orders and critical errors. It is certainly not an optimal and effective solution, and it is very difficult to keep it alive.
