Security Domains List
You build a security domains list by grouping systems that share the same trust rules. Each group holds apps, servers, or databases that need the same level of care. Many teams start by splitting production systems from test systems. They assign one broad role to each group for speed. When roles are too broad, one bad query can break many databases at once.

You build a security domains list by grouping systems that share the same trust rules. Each group holds apps, servers, or databases that need the same level of care. Many teams start by splitting production systems from test systems. They assign one broad role to each group for speed. When roles are too broad, one bad query can break many databases at once.
How to build a security domains list
A security domain is a boundary around a set of tools and data. Every item inside that boundary follows the same security rules and role checks. You start by listing all your databases, cloud servers, and internal apps. Next, you score each system based on the data it holds. Systems with card numbers, phone numbers, or emails go into a high-trust domain. Build tools and test servers go into a low-trust domain.
Standard frameworks also use a security domains list to organize security work. They split daily work into clear areas like identity, network rules, asset care, and software checks. Your engineering team can map each technical boundary to these core areas. Identity rules decide who can log in to a specific group of servers. Network rules block traffic between a test domain and a production domain. Asset rules track every database and server inside each boundary. This structure stops a breach in one area from spreading to another.
How teams assign roles across domains
Once you define your domains, you must tie them to your identity provider. Teams create user groups that match each domain in their list. A developer might hold a write role in the test domain. That same developer holds no role or a read role in production. Cloud platforms and database engines check these roles when a user logs in.
Teams also separate network zones for each domain on the list. They place production databases in private subnets with strict firewall rules. Test servers sit in separate subnets with their own keys and roles. This setup keeps test traffic away from live user data. Auditors review this map to see how you protect sensitive data.

What domain boundaries solve and what they miss
A clear domain map solves the problem of flat networks. It stops every engineer from logging in to every server by default. It also gives security teams a clear checklist for audits and reviews. You know which systems hold high-risk data and who has a role there.
Still, static domain boundaries leave a major operational gap open. Native domain roles only check who logs in at the start of a session. They do not inspect what individual queries or commands do in flight. Once an engineer logs in to a production domain, their role stays active. A valid user can still run a bad command that deletes a table. They can also run a broad query that pulls thousands of emails or national IDs. Static roles cannot rewrite matched fields in results or block one risky command on the fly.
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 runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
What are the main areas in a standard security domains list?
Most lists include identity and access, network safety, asset care, and risk management. They also cover data safety, daily operations, software building, and physical site rules.
How many technical domains should an engineering team create?
Start with three or four clear domains based on data risk. Most teams use separate domains for public services, internal tools, test systems, and production data.
Why do static security domains fail during live troubleshooting?
Engineers need temporary access to production domains to fix live bugs. Once they log in, static domain roles cannot limit which commands or queries they run.
