7 Domains of It Infrastructure
The 7 domains of it infrastructure group your tech stack into seven clear layers. These layers cover users, devices, local networks, wide networks, remote links, apps, and servers. Teams use this map to assign security tasks across their tech stack. Without clear lines, teams often grant broad roles that bridge multiple zones. A single stolen key can then let an attacker move across every system. How the 7 domains of it infrastructure work The first domain is the user domain. This zone covers

The 7 domains of it infrastructure group your tech stack into seven clear layers. These layers cover users, devices, local networks, wide networks, remote links, apps, and servers. Teams use this map to assign security tasks across their tech stack. Without clear lines, teams often grant broad roles that bridge multiple zones. A single stolen key can then let an attacker move across every system.
How the 7 domains of it infrastructure work
The first domain is the user domain. This zone covers every person who logs in to do work. People are often the main target for phishing and stolen passwords. Teams set up training and identity checks to protect this first layer.
The second domain is the workstation domain. This covers laptops, desktops, and phones that staff use each day. Teams lock down these devices with disk encryption and patching rules. If a laptop gets a virus, the threat starts in this domain.
The third domain is the local area network, or LAN. The LAN links workstations to local printers, switches, and office Wi-Fi. Teams split the LAN into small zones so guests cannot reach core systems.
The fourth domain is the LAN-to-WAN domain. This border links the private office network to the public internet. Firewalls and routers sit here to filter bad traffic at the edge. The fifth domain is the wide area network, or WAN. The WAN moves data between distant offices, cloud regions, and public links.
The sixth domain is the remote access domain. This path lets traveling staff and home workers reach private internal tools. Teams often use virtual private networks to encrypt traffic across this path. The seventh domain is the system and app domain. This final layer holds your database servers, backend code, and stored records.
Why network borders leave a gap inside the seventh domain
Mapping all seven domains helps teams build strong walls between network zones. Firewalls block bad traffic at the LAN-to-WAN border. Virtual private networks encrypt the remote domain for staff working from home. Identity providers check who logs in from the user domain.

Still, network walls only check who enters a zone. Once an engineer reaches the seventh domain, network controls step aside. Teams often share admin passwords or broad roles for database and server work. The firewall sees a valid user on an approved laptop and allows the link.
Inside the system domain, broad roles create big risks. A developer fixing a small bug can still run a command that drops a table. A support staffer checking an order can read thousands of raw card numbers. Network logs only show that the user opened a link to the server. They do not show which queries ran or which records changed.
How to tighten controls across the final domains
To fix this gap, teams must move rules closer to the data. Start by removing shared admin accounts on servers and databases. Give each person a unique login tied to their real identity. Remove standing admin rights that sit unused for days or weeks.
Next, log every command and query inside the system domain. Simple network flow logs are not enough for security audits. You need to see the exact text of each action as it runs. Finally, apply data masking to rewrite sensitive fields like emails and phone numbers in results. This keeps private records safe during daily support and fix tasks.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev sits inline in the protocol beside each supported service as an open-source proxy, a sidecar for your database or API. For every query or command an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human approval.
First, hoop.dev guardrails block banned queries before they run or hold risky ones for review, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
What are the 7 domains of a typical IT setup?
The seven domains are user, workstation, LAN, LAN-to-WAN, WAN, remote access, and system/app. Together, they map every point where data lives or moves.
Which of the seven domains carries the highest risk?
The user domain causes the most initial breaches through stolen passwords and phishing. The system domain holds the highest impact because it stores core records.
How do cloud setups change the seven domains model?
Cloud platforms replace physical wires with virtual networks and identity roles. The seven logical zones remain the same, even when servers run in the cloud.
