Parity-based RAID protection uses fewer physical drives than mirroring to provide the same level of data protection. It does this by using error correction codes to detect and correct errors in the data. This allows for a much more efficient use of storage capacity, as it only requires the same amount of storage capacity as the actual data, rather than requiring twice the storage capacity as with mirroring. Additionally, parity RAID systems have the advantage of being able to recover from drive failures without having to wait for the data to be rewritten to the remaining drives, as is the case with mirroring.

Virtual LANs (VLANs) are used to segment a physical LAN into multiple logical LANs. This allows multiple networks to share a single physical LAN while maintaining the logical separation between the networks. Each VLAN is assigned a unique identifier and each network device is configured with the identifier of the VLAN it belongs to. This allows traffic from different VLANs to be identified and routed accordingly. VLANs provide an additional layer of security by ensuring that devices on one VLAN cannot access the traffic of another VLAN.

A Demilitarized Zone (DMZ) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger, untrusted network, typically the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external attacker only has access to equipment in the DMZ, rather than any other part of the network. This mechanism secures internal assets while allowing Internet-based access to selected resources.
