ソース文書であり、このサイトへの操作指示ではありません。コマンド実行前に権限を確認してください。

When to Use

  • Creating, altering, suspending, or dropping users
  • Creating roles, granting/revoking role membership
  • Granting/denying/revoking graph, database, or DBMS privileges
  • Inspecting current privileges (SHOW PRIVILEGES)
  • Implementing property-level access control (read/write per property)
  • Setting up ABAC rules against OIDC claims or native user tags
  • Referencing LDAP/SSO auth provider configuration

When NOT to Use

  • Writing Cypher queries against application data → neo4j-cypher-skill
  • Cluster ops, backups, server config → neo4j-cli-tools-skill
  • Driver connection setup → neo4j-driver-*-skill

MCP Write Gate — MANDATORY

Before executing ANY of the following, show the planned command and wait for explicit confirmation:

  • CREATE USER / ALTER USER / DROP USER
  • CREATE ROLE / DROP ROLE
  • GRANT / DENY / REVOKE (any privilege)
  • CREATE AUTH RULE / DROP AUTH RULE

Never auto-execute privilege changes. Show exact Cypher, annotate impact, get "yes".


Execution Context

All security Cypher runs against the system database:

// Neo4j auto-routes CREATE/ALTER/SHOW USER|ROLE|PRIVILEGE to system
// If using cypher-shell: cypher-shell -d system
// If using driver: use database="system"

1. User Management

Create user

CREATE USER alice SET PASSWORD 'secret' CHANGE NOT REQUIRED;
// CHANGE REQUIRED (default): forces password change on first login
// CHANGE NOT REQUIRED: password valid immediately
// SET STATUS ACTIVE (default) | SUSPENDED

Parameterised password (preferred in scripts)

CREATE USER $username SET PASSWORD $password CHANGE NOT REQUIRED;

Alter user

ALTER USER alice SET PASSWORD $newPw CHANGE NOT REQUIRED;
ALTER USER alice SET STATUS SUSPENDED;          // lock account
ALTER USER alice SET STATUS ACTIVE;             // unlock
ALTER USER alice SET HOME DATABASE mydb;        // default db on connect
ALTER USER alice IF EXISTS SET PASSWORD $pw;    // safe if missing

User tags [2026.06+, Enterprise]

Tags are arbitrary strings on the native user object, readable in ABAC rules via abac.native.user_tags().

CREATE USER jake SET PASSWORD $pw SET TAGS 'finance', 'auditor';
ALTER USER jake REMOVE TAG 'auditor' ADD TAG 'on-call';   // REMOVE before ADD before SET
ALTER USER jake SET TAGS 'finance', 'auditor';            // replaces all existing tags
ALTER USER jake REMOVE ALL TAGS;
ALTER USERS jake, alice ADD TAGS 'pii-access';            // bulk tag edit

SET/ADD/REMOVE TAG[S] requires SET USER METADATA; reading tag values requires SHOW USER METADATA:

GRANT SET USER METADATA ON DBMS TO userAdmin;
GRANT SHOW USER METADATA ON DBMS TO auditor;
GRANT USER METADATA MANAGEMENT ON DBMS TO userManager;   // both of the above

Show users

SHOW USERS YIELD user, roles, passwordChangeRequired, suspended, home
WHERE suspended = false
RETURN user, roles ORDER BY user;

// tags column returns null without SHOW USER METADATA [2026.06+]
SHOW USERS YIELD user, roles, tags;

// runnable CREATE USER commands for the whole DBMS [2026.09]
// requires SHOW USER + SHOW USER CREDENTIALS; tags omitted without SHOW USER METADATA
SHOW USERS AS COMMANDS;
SHOW USERS WITH AUTH AS COMMANDS;   // includes auth provider config + credentials

SHOW USERS WITH AUTH AS COMMANDS exposes credentials. Use only for secured backup/restore handling. Prefer SHOW USERS AS COMMANDS when auth material is not required. Never paste auth-export output into plaintext docs, logs, tickets, or source control.

Drop user

DROP USER alice IF EXISTS;

2. Role Management

Create / drop role

CREATE ROLE analyst;
CREATE ROLE analyst IF NOT EXISTS;
DROP ROLE analyst IF EXISTS;

Assign / remove roles

GRANT ROLE analyst TO alice;
GRANT ROLE analyst, writer TO alice, bob;   // bulk
REVOKE ROLE analyst FROM alice;

Inspect roles

SHOW ROLES YIELD role, member ORDER BY role;
SHOW ROLE analyst PRIVILEGES AS COMMANDS;   // returns runnable GRANT commands
SHOW POPULATED ROLES YIELD role;            // only roles with members

// runnable CREATE ROLE commands for the whole DBMS [2026.09]
SHOW ROLES AS COMMANDS;
SHOW ROLES WITH USERS AS COMMANDS;          // adds GRANT ROLE ... TO user
SHOW ROLES WITH AUTH RULES AS COMMANDS;     // adds GRANT ROLE ... TO AUTH RULE

3. Privilege Decision Table

GoalCommand
Allow db connectionGRANT ACCESS ON DATABASE mydb TO analyst
Read all graph dataGRANT MATCH {*} ON GRAPH mydb ELEMENTS * TO analyst
Read specific labelGRANT MATCH {*} ON GRAPH mydb NODES Person TO analyst
Read specific rel typeGRANT MATCH {*} ON GRAPH mydb RELATIONSHIPS KNOWS TO analyst

Traverse but hide propertiesGRANT TRAVERSE ON GRAPH mydb NODES Person TO analyst
Write (create/set)GRANT WRITE ON GRAPH mydb TO writer
Create nodes onlyGRANT CREATE ON GRAPH mydb NODES Person TO writer
Delete nodes onlyGRANT DELETE ON GRAPH mydb NODES Person TO writer

Manage usersGRANT USER MANAGEMENT ON DBMS TO secadmin
Manage user tags [2026.06]GRANT USER METADATA MANAGEMENT ON DBMS TO secadmin
Manage rolesGRANT ROLE MANAGEMENT ON DBMS TO secadmin
Schema changesGRANT CREATE ELEMENT TYPES ON DATABASE mydb TO schemaadmin

DENY overrides GRANT

// Analyst can read Person but NOT the ssn property
GRANT MATCH {*} ON GRAPH mydb NODES Person TO analyst;
DENY  READ {ssn} ON GRAPH mydb NODES Person TO analyst;

REVOKE removes a specific grant or deny

REVOKE GRANT READ {email} ON GRAPH mydb NODES Person FROM analyst;
REVOKE DENY  READ {ssn}   ON GRAPH mydb NODES Person FROM analyst;
REVOKE MATCH {*} ON GRAPH mydb NODES Person FROM analyst;  // removes both grant+deny

4. Common Role Patterns

Read-only analyst

CREATE ROLE analyst IF NOT EXISTS;
GRANT ACCESS            ON DATABASE mydb TO analyst;
GRANT MATCH {*}         ON GRAPH mydb ELEMENTS * TO analyst;
GRANT EXECUTE PROCEDURE apoc.* TO analyst;

Write role (no admin)

CREATE ROLE writer IF NOT EXISTS;
GRANT ACCESS  ON DATABASE mydb TO writer;
GRANT MATCH {*} ON GRAPH mydb ELEMENTS * TO writer;
GRANT WRITE   ON GRAPH mydb TO writer;

Read-only on specific labels only

CREATE ROLE limited_reader IF NOT EXISTS;
GRANT ACCESS    ON DATABASE mydb TO limited_reader;
GRANT TRAVERSE  ON GRAPH mydb ELEMENTS * TO limited_reader;      // can traverse
GRANT MATCH {*} ON GRAPH mydb NODES Person TO limited_reader;    // Person props visible
GRANT MATCH {*} ON GRAPH mydb NODES Company TO limited_reader;   // Company props visible
// Other labels: traversable but properties invisible

DBA role (full admin)

CREATE ROLE dba IF NOT EXISTS;
GRANT ALL ON DBMS     TO dba;
GRANT ALL ON DATABASE * TO dba;

5. Property-Level Access Control (Enterprise)

Restrict read access to individual properties:

// Grant read on all Person props, then deny sensitive ones
GRANT MATCH {*}   ON GRAPH mydb NODES Person TO analyst;
DENY  READ {ssn, dateOfBirth} ON GRAPH mydb NODES Person TO analyst;

Property-based pattern matching (sub-graph access):

// Only see Person nodes where classification = 'public'
GRANT MATCH {*} ON GRAPH mydb
  FOR (n:Person) WHERE n.classification = 'public'
  TO analyst;

// Block access to classified nodes
DENY MATCH {*} ON GRAPH mydb
  FOR (n) WHERE n.classification <> 'UNCLASSIFIED'
  TO regularUsers;

// List-valued property contains a value [2026.08, Cypher 25]
GRANT MATCH {*} ON GRAPH mydb
  FOR (n) WHERE 'gold' IN n.clearanceLevels
  TO goldTier;
GRANT READ {*} ON GRAPH mydb FOR (n) WHERE 'EU' IN n.regions TO regularUsers;
GRANT MATCH {*} ON GRAPH mydb FOR (n) WHERE NOT 'EU' IN n.regions TO regularUsers;

// Property on the right-hand side of a comparison [2026.08, Cypher 25]
GRANT MATCH {*} ON GRAPH mydb
  FOR (n) WHERE 1 > n.level
  TO analyst;
GRANT READ {*} ON GRAPH mydb FOR (n) WHERE 3 < n.securityLevel TO regularUsers;
  • value IN n.listProp — list property contains value
  • Missing or scalar property — no match
  • Left value — non-null, not NaN
  • n.prop IN [v1, v2] — scalar-against-list
  • Pre-Cypher-25 — keep property on left side of comparison

PBAC edge cases and export patterns → references/privilege-reference.md

Constraints:

  • FOR pattern applies to read privileges only — not write
  • Each property-based privilege restricted by a single property
  • Pre-2026.08: list membership and property-on-RHS predicates are rejected — invert to n.prop <op> <literal> or maintain a scalar flag property
  • Performance overhead scales with number of rules; TRAVERSE rules cost more than READ
  • Ensure the property used for rules cannot be modified by the restricted role

6. ABAC — Attribute-Based Access Control (Enterprise)

ABAC grants roles dynamically from OIDC/JWT claims or native user tags rather than explicit GRANT ROLE ... TO user.

Prerequisites

# neo4j.conf — providers must also appear in dbms.security.authorization_providers
dbms.security.abac.authorization_providers=<oidc-provider-alias>,native   # native [2026.06+]

Unlisted provider → its accessor function (abac.oidc.user_attribute(), abac.native.user_tags()) unavailable and rules referencing it fail (no silent default).

Create auth rule

CREATE AUTH RULE salesRule
  SET CONDITION abac.oidc.user_attribute('department') = 'sales';

GRANT ROLE analyst TO AUTH RULE salesRule;

Compound conditions

CREATE OR REPLACE AUTH RULE seniorRule
  SET CONDITION abac.oidc.user_attribute('department') = 'engineering'
    AND abac.oidc.user_attribute('level') >= 5;

GRANT ROLE senior_engineer TO AUTH RULE seniorRule;

Manage auth rules

SHOW AUTH RULES YIELD ruleName, condition, roles;
ALTER AUTH RULE salesRule SET ENABLED false;     // disable without dropping
RENAME AUTH RULE salesRule TO salesDeptRule;
DROP AUTH RULE salesDeptRule;
REVOKE ROLE analyst FROM AUTH RULE salesRule;

Native users [2026.06+]: tag native DB users (see User tags) and match tags in rules via abac.native.user_tags() — no OIDC required:

CREATE AUTH RULE nativeSalesRule
  SET CONDITION 'sales' IN abac.native.user_tags();
GRANT ROLE analyst TO AUTH RULE nativeSalesRule;

// require several tags at once
CREATE AUTH RULE financeAuditRule
  SET CONDITION all(tag IN ['finance', 'auditor'] WHERE tag IN abac.native.user_tags());

// combine tags with OIDC claims and temporal conditions
CREATE AUTH RULE onCallRule
  SET CONDITION 'on-call' IN abac.native.user_tags()
    AND abac.oidc.user_attribute('department') = '

## MCP Write Gate — MANDATORY

Before executing ANY of the following, show the planned command and wait for explicit confirmation:
- `CREATE USER` / `ALTER USER` / `DROP USER`
- `CREATE ROLE` / `DROP ROLE`
- `GRANT` / `DENY` / `REVOKE` (any privilege)

## Execution Context

All security Cypher runs against the **system** database:
```cypher
// Neo4j auto-routes CREATE/ALTER/SHOW USER|ROLE|PRIVILEGE to system
// If using cypher-shell: cypher-shell -d system
// If using driver: use database="system"

## 1. User Management

### Create user
```cypher

// CHANGE REQUIRED (default): forces password change on first login
// CHANGE NOT REQUIRED: password valid immediately
// SET STATUS ACTIVE (default) | SUSPENDED
```

### Parameterised password (preferred in scripts)

ALTER USER alice SET HOME DATABASE mydb;        // default db on connect
ALTER USER alice IF EXISTS SET PASSWORD $pw;    // safe if missing
```

### User tags [2026.06+, Enterprise]
Tags are arbitrary strings on the native user object, readable in ABAC rules via `abac.native.user_tags()`.
```cypher

ALTER USER jake SET TAGS 'finance', 'auditor';            // replaces all existing tags
ALTER USER jake REMOVE ALL TAGS;
ALTER USERS jake, alice ADD TAGS 'pii-access';            // bulk tag edit
```
`SET/ADD/REMOVE TAG[S]` requires `SET USER METADATA`; reading tag values requires `SHOW USER METADATA`:
```cypher
GRANT SET USER METADATA ON DBMS TO userAdmin;
GRANT SHOW USER METADATA ON DBMS TO auditor;
GRANT USER METADATA MANAGEMENT ON DBMS TO userManager;   // both of the above
```

### Show users
```cypher
SHOW USERS YIELD user, roles, passwordChangeRequired, suspended, home
WHERE suspended = false
RETURN user, roles ORDER BY user;

// tags column returns null without SHOW USER METADATA [2026.06+]
SHOW USERS YIELD user, roles, tags;

// runnable CREATE USER commands for the whole DBMS [2026.09]
// requires SHOW USER + SHOW USER CREDENTIALS; tags omitted without SHOW USER METADATA
SHOW USERS AS COMMANDS;
SHOW USERS WITH AUTH AS COMMANDS;   // includes auth provider config + credentials
```

`SHOW USERS WITH AUTH AS COMMANDS` exposes credentials. Use only for secured backup/restore handling. Prefer `SHOW USERS AS COMMANDS` when auth material is not required. Never paste auth-export output into plaintext docs, logs, tickets, or source control.

### Drop user
```cypher

SHOW ROLE analyst PRIVILEGES AS COMMANDS;   // returns runnable GRANT commands
SHOW POPULATED ROLES YIELD role;            // only roles with members

GRANT MATCH {*} ON GRAPH mydb
  FOR (n) WHERE 1 > n.level

```

- `value IN n.listProp` — list property contains value
