A typical deployment includes virtual desktops, hypervisors or cloud compute, images, storage, connection brokers, gateways, identity services, management planes, remote-display protocols, networks, and client software or browsers.
VDI can centralize desktop administration and keep some application data away from endpoint storage, but it also concentrates access and creates high-value control planes. Persistent and non-persistent desktops require different approaches to change, evidence, user data, and recovery.
Key points
Protect access and brokeringStrongly authenticate users and administrators, authorize resource requests, secure gateways and certificates, limit exposure, monitor sessions, and isolate privileged management.
Secure the hosted platformHarden hypervisors, brokers, images, agents, and virtual networks; control image provenance and updates; separate tenants and roles; protect storage; and detect unauthorized persistence.
Govern session channelsControl clipboard, file, drive, printer, audio, camera, and USB redirection; manage downloads and caches; protect tokens and reconnect behavior; and retain proportionate evidence.
Important limitationVDI does not inherently secure the endpoint or session. A compromised client can capture credentials, input, screens, tokens, or authorized data, while a compromised control plane can affect many desktops.
