A useful review starts with visibility. Before buying another tool, understand what is connected, who can administer it, and which systems should be separated.
1. Define the authorized scope
List the locations, networks, devices, cloud services, and owners included in the review. Record what is explicitly out of scope.
2. Build an asset and access picture
Create a working inventory and identify every administrative account. Unknown devices and shared administrator credentials deserve early attention.
- Routers, switches, access points, and firewalls
- Servers, endpoints, printers, and IoT devices
- Administrative, service, and guest accounts
3. Review separation and exposure
Check whether employee, guest, server, management, and IoT traffic are separated appropriately. Confirm that remote administration is intentional and protected.
4. Prioritize fixes
Rank findings by likely business impact and effort. A short, owned action list is more useful than a long report no one can implement.
