TGW: Remote Network Operations and Time Machine Backup Continuity

Client background

• In 2022Q3, TGW's IT contact came from the earlier TTW collaboration and brought operational trust in WalksCloud's managed model; even after multiple handover changes, cooperation remained stable.
• The site primarily used three managed Aruba APs and one Mikrotik router, plus a separate classroom segment (covered in a different case).
• The new requirement was secure Time Machine backup from Mac endpoints back to office NAS for evidence-grade retention.

Challenges

1. Short deployment lead time: TGW wanted to adopt proven patterns quickly, including AdGuard Home, LDAP/RADIUS, and remote inspection workflows used in TTW.
2. No general VPN requirement, but Time Machine support was required: TGW did not need OpenVPN access; it needed a controlled VPN path only for backup traffic.
3. Backup traceability for security investigations: backup records needed to remain auditable after writing into NAS storage.

WalksCloud approach

1. Remote managed operations with DNS/LDAP/RADIUS

   • Reused the proven TTW baseline: AdGuard Home filtering (public filters plus homelab validation), LDAP/RADIUS self-service management, and CI/CD-driven update workflows.
   • Maintained SNMP/Syslog visibility under WalksCloud-managed channels and designed office/guest segmentation around Aruba AP and Mikrotik routing.

2. Jamf Trust plus Time Machine backup path

   • Used Jamf Security Cloud/Jamf Trust as the only approved transport, accepting encrypted connections from Jamf Trust app clients.
   • Defined a controlled Time Machine flow: enable backup from Jamf Self Service, connect through Jamf Trust, and write to per-user folders on office NAS.
   • Preserved backup logs and NAS journal records as traceable evidence for incident investigation.

3. Long-term operations and automation

   • Renewed DNS/RADIUS certificates weekly through CI/CD ACME workflows.
   • Shared user/group and Jamf automation patterns with TTW, enabling fast patch and policy rollout.

Outcomes

• TGW achieved TTW-equivalent remote operations stability in the new office without a long rediscovery phase.
• Jamf Trust plus Time Machine delivered traceable backup continuity and faster incident recovery readiness.
• With DNS filtering, LDAP/RADIUS controls, and self-service operations in place, WalksCloud intervention remained exception-based and low-disruption.
