Introducing Zero Trust as an IT Security Strategy
The battle to protect corporate assets has long since moved beyond the the corporate network firewall to the Internet, the cloud and the home office. If you only try to protect your corporate network’s perimeter, you are fighting a losing battle. A Zero Trust Architecture (ZTA), on the other hand, precisely addresses these problems, which hardly seem to be solvable with classic approaches. In this context, classic means purely using firewalls and network segmentation, true to the motto of protecting the outer boundaries of the corporate network. Once an attacker has overcome these, there is hardly any protection left. Zero Trust, on the other hand, means that trust, e.g., in the corporate network itself, is not granted for no reason, but that each access and data flow is repeatedly legitimized individually.
The introduction of Zero Trust requires the support of the entire IT organization of a company due to its diversity and always means a tightrope walk, e.g. between usability and security. This complexity and the effort involved often appear to be an almost insurmountable hurdle.
Particularly with a program of this scope, important strategic considerations should be clearly addressed at an early stage. In addition, the basic paradigm of the approach must be defined, which depends individually on the character of the company. Introducing a ZTA architecture, it helps to focus on the relevant pillars of a Zero Trusts approach and to take a structured and pragmatic approach. This is because added value is created where a ZTA interacts with the business and its processes to enable value creation together with security, not where the business has to adapt to the solution.
The resulting benefits are:
- Future-oriented IT security strategy
- A secure path for mobile workforce
- Clear orientation for cloud strategy
- Added value through the integration of the business
- Sustainable and long-term security gain
