+# Appendix B: ACL descriptors
+
+#### Querying the ACL system
+
+MISP allows site admins to query the ACL system for various types of data. This can be interesting when tuning for example WAF access to MISP. All applicable queries can be requested via /servers/queryACL
+
+#### Getting a list of URLs accessible to a role
+
+~~~~
+https://<misp url>/servers/queryACL/printRoleAccess/<role id>
+~~~~
+
+The above URL will return a JSON with all accessible URLs for the given role ID. If no Role ID is provided, a JSON containing all roles and their access lists will be returned. 
+
+Example:
+
+~~~~json
