Inventory systems only know what they were told
A CMDB or endpoint platform may miss equipment that was never enrolled, was rebuilt, changed IP address or belongs to a different team.
Network evidence provides an independent view
Reachability, DNS names, service responses and device protocols can reveal systems that are absent from formal inventory.
Unknown does not automatically mean malicious
A discovered host may be a forgotten printer, temporary test VM, vendor appliance or legitimate system with bad documentation. The value is that it becomes reviewable.
Auditor supports reconciliation
Scantide Auditor can compare discovered systems with CMDB-style data so administrators can focus on the differences rather than manually comparing spreadsheets.

Field experience from the archive
Historical source · JufCorp: Security Reality Check: Why a Perfect Score Doesn't Mean You're SafeServer Inventory: Maintain complete asset inventory of all servers (physical, virtual, cloud). Include IP addresses, purposes, owners, and last patched dates.
Forgotten Servers: Regularly scan your network for unknown or forgotten servers. These become prime targets - unpatched, unmonitored, and exploitable.
Implementation: Configure these DNS servers in your router/firewall for network-wide protection, or set them on individual devices. Many services offer deployment guides for various platforms.
Historical source · JufCorp: Securing server environments – part II – NetworkingDon’t have computers in the reception connected to the corporate network such as guest access systems. There is absolutely no need for external visitors to be able to browse your internal network.
Always have a good monitoring software running and checking your network for new devices. If you start seeing devices with MAC addresses with 00-00-00-BE-50-00-DE-AD .. well. its too late . you’re toast. Personally I favor SpiceWorks but there are lots of monitoring software solutions out there. Take your pick. Basically, you need to have a clue of what’s going on your network and , even mores so. You need to know why. You need to monitor bandwidth usage and also have monitoring points on your network , both from internal point and from external.
Historical source · JufCorp: Securing server environments - part II - NetworkingIf you really want to restrict network access, most switches and wireless routers have the ability to set up MAC address for filtering and access but the downside is of course it's an administrative nightmare if you many devices and users. If you enable those features you'll have to keep track of each MAC address on your network which can be time consuming. It does tighten your securiy of course.
