Patch Rhythm + Inventory Template
(Low‑Drama Updates)

A simple schedule + what to inventory + how to communicate maintenance windows.

Goal

Make patching predictable and low‑risk: small, regular updates instead of big, scary, overdue changes.

1) Recommended patch rhythm

Cadence	What	Examples	Notes
Weekly (optional)	Critical security fixes	Browser zero-days, emergency vendor advisories	Only when needed; keep it rare.
Monthly	Endpoints + apps	Windows/macOS, Office apps, browsers, PDF reader	Pick a “Patch Tuesday + 1 week” window.
Quarterly	Edge/infrastructure firmware	Firewalls, routers, Wi‑Fi controllers/APs, NAS, switches	Planned after-hours or low-traffic window.
Annually	Lifecycle review	End-of-life devices, OS upgrades	Align to budgeting.

2) “What to inventory” (minimum viable)

Endpoints: laptops/desktops, OS version, warranty date
Network: router/firewall model + firmware, switches, Wi‑Fi APs/controller
Servers/VMs: roles (file, app, DB), OS versions
SaaS: Microsoft 365 tenant, security baseline status, admin accounts
Backups: what is backed up, where, and last successful restore test

3) Inventory table (copy/paste)

Asset	Type	Model	OS/FW	Owner	EOL/Warranty	Notes
__________	Endpoint/Firewall/Wi‑Fi/Switch/Server	__________	__________	__________	__________	__________
__________
__________

4) Maintenance window message (customer/staff template)

Copy/paste into email or Teams:

Scheduled maintenance: [Date] between [Time].
Expected impact: [brief] (e.g., short internet interruption / Wi‑Fi restart).
Purpose: security and reliability updates.
If you notice issues after the window, report them to: [contact].

5) Risk reduction checklist (before you patch)

Confirm last good backup (or config export for network gear).
Do updates in a quiet window.
Have a rollback plan (previous firmware/config ready).
Validate after: internet, Wi‑Fi, VPN, key apps, printing, POS.
