Hands-on network and infrastructure experience, applied to ISO/IEC 27001 auditing that understands what is actually running.
About me
I work in network and IT infrastructure operations: inventorying network devices, rebuilding topology maps, reviewing configurations and looking after servers.
Along the way I noticed that a lot of security risk hides in undocumented configurations and devices nobody has inventoried. That is why I am studying ISO/IEC 27001 systematically: to bring a technical background into security auditing, so the audit covers what is actually running, not only the paperwork.

Latest notes
Notes from my day-to-day work and self-study. Each one ends with an ISO/IEC 27001:2022 audit perspective.
Cisco Switch Inventory Commands
Commands, steps and caveats for inventorying Cisco switches and rebuilding the network topology when taking over an existing network.
macOS Terminal Basics
From cd, ls and /dev to file operations, network checks and connecting to network devices over a console cable, the macOS terminal commands I use most.
12 Common Server Roles and Where They Store Data
What 12 common server roles do, typical products, how they are deployed at different scales, and the four main ways servers store data.
