Role-based access control
Permissions follow the job, not the person.

Short answer. Role-based access control (RBAC) gives people permissions through roles, such as partner, accountant or receptionist, instead of listing permissions person by person. NIST describes it as a model in which permitted actions on resources are identified with roles rather than individual identities: each user is assigned one or more roles, and each role carries one or more privileges. When someone joins, moves or leaves, you change their roles, not dozens of separate settings. For an AI system, roles decide who can query which document collections, who can approve an agent’s action, and who can read the activity log.

01

How RBAC works

Users are assigned to roles, roles hold privileges, and privileges permit operations on resources. Security administration then means working out which operations people in a given job must perform and assigning employees to the proper roles. NIST’s project page says RBAC was formalised in 1992 by David Ferraiolo and Rick Kuhn, that NIST’s model was adopted as American National Standard 359-2004, and that it was revised as INCITS 359-2012. The project is now archived.

RBAC and its neighbours

ApproachHow access is decidedWatch for
Per-person list (ACL)A list of named people on each itemNIST: administrators specifying lists user by user find it costly and prone to error
RBACThe roles a user holdsToo many roles; leavers and movers keeping old roles
Attribute-based (ABAC)Rules over attributes such as department, device and timeNIST: can be easy to set up but complex to manage

Common mistakes

  • Too many administrators. Administrator should be a role for a few people, not a default.
  • Shared accounts. A shared login defeats roles, because nobody can tell who did what.
  • Stale membership. Review role membership at every joiner, mover and leaver event, and at least every quarter.
  • One person holds every duty. Keep the people who run the system apart from the people who read its log. NIST’s control for protecting audit information suggests limiting audit logging management to a subset of privileged users.
  • Roles that exist only on paper. Test with a real low-privilege account.
05

RBAC and AI search

Roles must reach the AI’s search too. OWASP’s guidance on vector and embedding weaknesses warns that misaligned access controls can let a model retrieve and disclose content the person asking could not open directly, and recommends permission-aware stores. After setting up a document collection, test with two accounts: one in a role that may see a document, one that may not.

06

Where ANVE stands

ANVE is built for many named users. Its security page (/security) says the roles today are administrator and user, and that teams, finer roles and single sign-on are not on ANVE yet. An administrator must approve cloud models, connectors and the tools an agent can use. Who can read whose chats is a question to settle in writing before a paid pilot.

Questions people ask

What is the difference between RBAC and an access control list?
An access control list names the people allowed on each item. RBAC names the roles, and people inherit permissions through the roles they hold. NIST says per-user lists are costly and error-prone to administer.
How many roles does an office need?
Usually one for each job function, plus a few special roles for administration and audit. If you need dozens, the roles are probably describing people rather than jobs.
Does RBAC stop the AI revealing a document the user cannot open?
Only if the AI’s search respects the same permissions. OWASP recommends permission-aware stores. Test it with a user who should not see the document.
Is RBAC the same as least privilege?
No. Least privilege is the principle that each user gets only the access needed. RBAC is one way to apply it.
What roles does ANVE have?
According to its published security page, administrator and user today. Teams, finer roles and single sign-on are not on ANVE yet. ANVE is pre-release.

What is not real yet

No sealed ANVE unit exists; every image of the appliance on this site is a labelled render. The software runs today on a development machine. No customers yet, no certifications, no delivery date, and the final price is not announced.
