Linux Server Management

Hardened Linux hosts, patch cadence, and operational baselines for server fleets.

Linux server management for teams still running important workloads on VMs or bare metal: hardening baselines, patch processes, user access hygiene, and monitoring hooks. We document how hosts are built and maintained so operations do not depend on undocumented SSH folklore.

Who it’s for

  • IT and platform teams operating Linux VM fleets
  • Companies with hybrid cloud and on-prem Linux hosts
  • Product teams needing reliable app servers without full container platforms

Problems we address

  • Servers were configured once and drifted for years
  • Patching is irregular and poorly tracked
  • Access and sudo rights are overly broad

Expected outcomes

  • Hardening and baseline configuration as code where practical
  • Patch and reboot cadence with change notes
  • Least-privilege access and key management practices

This service focuses on Linux. Windows server work can be discussed separately if it is part of the same estate.
