Datacenter Isolation
Isolated datacenters block lateral threats
Summary
A large percentage of deployed high-availability architectures rely on cross-site service clustering, which increases cyber risk by creating shared attack surfaces. RMF, when deployed in Federated or Independent architectures, takes a different approach: each data center operates independently, with no shared clustering or storage. This isolation blocks lateral movement during an attack and ensures a clean, uncompromised environment is always available for recovery.
Clustering Requires Broad and Persistent Trust
Traditional cross-site clustering relies on deep system-level integration between data centers, typically involving shared authentication domains, real-time database replication, and mutual access to control services and storage. For the cluster to function seamlessly, each site must implicitly trust the other across all layers of the stack. This broad trust model means that any compromise—whether through malware, misconfiguration, or insider threat—can rapidly propagate across the entire cluster. The exact mechanisms that deliver high availability also erase meaningful security boundaries between sites, violating zero-trust principles and increasing the blast radius of a breach.
RMF Service Architecture Enforces Narrow, Explicit Trust
The RMF solution (when deployed in Federated or Independent architectures) replaces clustering with a service-based model that treats each data center as an independent entity. There is no requirement for shared authentication, storage, or real-time database replication. Instead, RMF operates through a lightweight service that connects the two sites over a narrow, explicitly defined communication channel with limited privileges and no direct system-level access. This design dramatically reduces the trust surface and prevents lateral movement between sites. Even if one site is compromised, the other remains fully insulated. By eliminating the need for persistent cross-site trust, RMF aligns with zero-trust architecture and provides a far stronger foundation for cybersecurity and resilience.
