ZERO TRUST IN IT: A SHIFT FOR CYBER SECURITY
The modern IT landscape is facing unprecedented challenges. Advancing digitalisation, cloud computing, mobile workplaces and the Internet of Things (IoT) are constantly expanding the attack surface. In this context, the Zero Trust model is becoming increasingly important. As the HWS Group, a leading IT service provider with renowned customers from the banking, insurance and healthcare industries, we would like to give you an insight into the essential components and benefits of Zero Trust: Zero Trust Network Access (ZTNA), Zero Trust Security and Zero Trust Architecture.
Zero Trust Network Access (ZTNA)
ZTNA is a central component of the Zero Trust model. In contrast to traditional VPN solutions, which grant a user comprehensive network access after successful authentication, ZTNA follows the principle of minimal access. Each user and each device is only granted the absolutely necessary access to specific resources. This is achieved through continuous authentication and authorisation.
The use of ZTNA significantly reduces the attack surface. Even if an attacker compromises access data, the opportunities to cause damage remain very limited. For our customers in the banking and insurance sector, this means that sensitive customer data and financial transactions are better protected.
Zero Trust Security
Zero Trust Security is based on the principle “Trust no-one, check everything”. Instead of perimeter-based security measures based on the assumption of a secure internal network, every access is strictly controlled and monitored. Key technologies here include:
- Multi-factor authentication (MFA): Additional layers of security to verify the identity of users.
ย
- Endpoint protection: Comprehensive monitoring and protection of end devices, including mobile devices.
ย
- Micro-segmentation: Division of the network into smaller, isolated segments to prevent lateral movement by attackers.
ย
- Continuous monitoring and logging: Real-time monitoring and logging of all activities to quickly recognise and respond to threats.
ย
Particularly in the healthcare sector, where patient data is subject to the highest level of confidentiality, Zero Trust Security ensures that only authorised persons have access to critical information and that it is managed securely.
Zero Trust Architecture
Zero Trust Architecture is the basic structure that supports the Zero Trust principle. It comprises several levels and components that work together seamlessly:
ย
- Identity and access management (IAM): Management of user identities and access rights.
ย
- Security policy engine: Automated policies to control access decisions based on user role, location, device and other factors.
ย
- Data encryption: End-to-end encryption of data at rest and in transit.
ย
- Threat intelligence: Integration of threat intelligence services for early detection and defence against attacks.

For companies in the banking and insurance sectors, implementing a zero trust architecture means that they not only fulfil regulatory requirements, but can also significantly increase their resistance to cyber attacks. Hospitals and clinics benefit from a robust security architecture that protects sensitive patient data and medical systems.
