Small office network documentation basics

Networks drift. Without a single page of truth, troubleshooting becomes archaeology. Documentation is for future panic, not for filing cabinets.

Minimum viable diagram

ISP handoff, modem, router or firewall, switches, APs, VLAN IDs, and where servers or NAS live. Note management IPs and which ports are WAN-only.

Credentials and MFA

Store admin logins in a vault with MFA enrollment documented. For security framing on configuration management, NIST is a steady reference: NIST CSRC.

Change log

Short dated notes when VLANs or firewall rules change. Pair with Wi-Fi basics and project sanity checks.
