Zero Trust means “trust no device and trust no user.” It constantly re-evaluates access for every user and system. All devices and user identities undergo continuous multifactor verification. This approach enhances security by minimizing the attack surface and reducing the impact of potential breaches. Zero Trust acknowledges that threats can originate from both inside and outside the network perimeter.
Infrastructure services often differ because they must run and connect when no other services are available. Infrastructure software like VMware vSphere uses features such as Secure Boot, Trusted Platform Modules, VIB signing and verification, and host attestation. These features build assurances that the infrastructure can be trusted in its current configuration. They create a chain of trust from hardware through the hypervisor and into virtual machines.
Organizations can apply Zero Trust techniques to infrastructure administration. One approach organizations can take is to work from the assumption (valid or not) that a desktop and a user account in their organization is compromised. While grim, this outlook fosters a better mindset for secure system design rooted in Zero Trust. It prompts administrators to implement strict access controls, network segmentation, and continuous monitoring. Subsequently, these organizations can better detect and contain breaches if they occur, limiting potential damage and data loss.
Implementing Zero Trust in infrastructure requires a multi-layered approach. This includes:
- Strong identity and access management
- Micro-segmentation of networks
- Least privilege access principles
- Continuous monitoring and logging
- Regular security audits and penetration testing
Zero Trust principles help protect against both external threats and insider risks. They provide a framework for securing modern, complex IT environments that span on-premises, cloud, and hybrid infrastructures. While challenging to implement, Zero Trust offers a robust defense against evolving cyber threats.
