Moving beyond perimeter-based cybersecurity
Conventional perimeter-based security frameworks assume that all services, devices, and users within one’s own network are trustworthy. Traffic and access from outside the network, on the other hand, are considered potentially dangerous and must be analyzed and restricted. But this means that once someone has penetrated the company network, there are hardly any security measures left to prevent dangerous activities, e.g., an attacker trying to gain administrator rights throughout the network environment.
The zero-trust model stands for a change in thinking compared to traditional concepts as it treats all devices, services, and users as equally untrustworthy. The basic assumption is that in a digitalized work environment, the interpersonal concept of human trust is not a valid principle of cybersecurity anymore, if it ever was.
