You use the keycloak open source identity and access management docs to set up single sign-on. These guides show you how to create realms, add users, and assign roles for your apps. Most teams start by linking their user directory to a central realm. They then map broad group roles to internal tools and databases. When those roles are too wide, any logged-in user can run risky commands.
How the keycloak open source identity and access management docs explain setup
Keycloak works by grouping your users and apps into separate spaces called realms. Each realm holds its own user list, login rules, and role maps. When a user tries to log in, the app sends them to the realm login page. The user enters their password and passes a second factor check. The server then checks its directory and issues a signed token to the user.
Inside the guides, you learn how to build clients for each web app or service. A client represents a single tool that trusts the central identity server. You choose standard protocols like OpenID Connect or SAML to pass identity data. The token carries the user profile, email, and assigned roles back to the app. Your app reads the token to decide what pages the user can open.
Teams also use the manuals to link existing directories like LDAP or Active Directory. This setup lets workers log in with one password across many internal tools. Admins can set password rules, session timeouts, and multi-factor steps in one place. When someone leaves the team, revoking their account in the realm blocks new logins right away.
What central identity solves and where the security gap remains
A central identity server solves the problem of scattered passwords and manual account creation. Your security team gets one place to check who logged in and when they did it. You can enforce strong login checks across web apps without rewriting every single tool. Auditors can review your realm settings to confirm that only active staff hold accounts.
Still, an identity server only checks who a person is at the front door. Once the user gets a valid token or opens a database session, the identity check ends. The login server does not watch the SQL queries or shell commands that run next. If an engineer logs in with a write role, they can drop a table by mistake.

Static roles also struggle to protect sensitive fields inside your production tables. A developer might need to read a customer table to fix a bug. With standard role checks, that developer reads full rows with emails, phone numbers, and card numbers. To control live queries and mask fields in results, teams need controls at the command level.
Best practices for managing realms and user roles
Start by keeping your admin realm separate from the realms that serve your daily apps. Use the master space only to create and manage other isolated realms. Next, group permissions into clear job roles instead of assigning rights to single users. Keep token lifetimes short so that stolen or old sessions expire within minutes.
Review your role mappings every month to remove extra rights that staff no longer need. Pair your login checks with runtime controls that inspect every query and command in flight. When you combine strong login checks with live command rules, you reduce the risk of data leaks.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What is the main purpose of a realm in Keycloak?
A realm acts as an isolated space for a set of users, roles, and apps. You use realms to keep test accounts separate from production users and rules.
Can Keycloak control which SQL queries a logged-in user runs?
No, the server only checks user identity and issues login tokens at the start. It cannot inspect or block individual database queries or shell commands during a session.
How does data masking work alongside an identity provider?
The identity provider verifies who the user is before they open a tool. A runtime control then rewrites matched fields like emails or card numbers in query results.
