How it works

The operation of RBAC is based on the relationship between three components: users, roles and policies or permissions. Policies are associated with roles, and each user can belong to one or more roles.

Since the policies are not directly related to users, it is not necessary to assign them to each user. Simply assign the user to the appropriate role. The process of updating the permissions of an entire group of users is also made easier thanks to this structure.

After configuring RBAC, there will be users that can only see and do certain actions on specified resources that have previously been established. For example, it can be ensured that members of a Security-team have ‘read’ access to all agents, while the Sales-team has ‘read’ and ‘modify’ permissions only to agents in their department (but not delete permissions).

Actions, resources and effect

Policies control the Wazuh API permissions using three elements: actions, resources, and effect.

Actions represent a hierarchy of actions that a user may perform. They indicate both the element to which the action belongs and the action itself. The structure they follow looks like the example below, where restarting agent is specified.


Resources are any entity that can be subject to an action. The set of resources is dynamic, but the types are static. Some examples of resources are “agent 001”, “agents in group default” or “node of a cluster”. The symbol * can be used as a wildcard to indicate all the resources of a type, instead of specifying them one by one. For example:


Effect can only be “allow” or “deny”, depending on the effective permission to be applied.

RBAC modes

RBAC in Wazuh can be configured in two different and opposite ways: black and white. The choice of one mode or another determines what will the behaviour of the created policies be. If the parameter effect of a policy is set to allow, that policy will be allowed in both black and white mode. If the effect is deny, it will be denied in both black and white. Therefore, the RBAC mode only affects those actions that are not specified within each policy.

  • White list mode: everything is forbidden. The administrator configures roles to give permissions.

  • Black list mode: everything is allowed. The administrator configures roles to restrict permissions.
