In the last blog post "What elements does a ZERO trust model consist of" we talked about the pillars of a Zero Trust architecture. In this article, we explain step by step how to implement Zero Trust in your company.
Zero-Trust strategy protects against penalties
The primary goal of Zero-Trust is to protect businesses from what is known as "advanced threats" and the effects of data theft.
When cybercriminals steal intellectual property, it leads to lost revenue. When attackers steal sensitive customer data, data breaches and their solutions can result in high costs. In addition, legal disputes, governmental investigations and damage to the company's reputation are often the result.
Zero Trust does not prevent every conceivable attack or breach, but an IT security architecture according to Zero Trust ensures that companies do not fall victim to simple attacks or that these are not discovered for months, perhaps even years. Security experts who are guided by Zero Trust as the main driver of their IT security strategy fulfil many compliance requirements with significantly greater efficiency.In doing so, a Zero Trust ecosystem should be geared to the business area of every company. Different industries such as eCommerce, energy or finance have different potential entry points for attackers. It is not enough to simply provide technologies. Internal processes, organisational measures and employee awareness of potential risks must also be taken into account.
Six steps to introducing Zero Trust in companies
With the following six steps, we provide you with an initial guide on how to implement Zero Trust and thus comprehensive protection of business-critical data in your own organisation.
Step 1: Assessment
In the first step, it is important to define the organisational framework. To do this, a number of questions must be answered as precisely as possible:
- What should be protected and why?
- Where are these digital and physical assets located - in the cloud or on local servers?
- Which data is classified as public and which is highly sensitive?
Step 2: Discovery & InventoryNext, all data is visualised in an inventory in order to identify further security-relevant aspects and potential weaknesses. The inventory includes all connected hardware as well as software and operating systems.
Step 3: Preventive measures
The possible measures to eliminate cyber threats from the outset and ensure data integrity are numerous. Some of the most important tools are:
- Disk and file & folder encryption
- Device control
- Application Control with whitelisting
- Identity & access management
