fiware - Can PEP proxy discriminate entities? -

-

can pep proxy (working idm keyrock) allow access entities of orion?

example scenario:

  1. there 2 types of entities on orion classified entity_type:
    • kitchen , bathroom
  2. user plumber can modify/comsume bathroom type entities.
  3. user cook can create/comsume kitchen type entities.
  4. user admin can modify/create/comsume all entities.

as far know, neither reference implementation of pep proxy (wilma) or ti+d's version (steelskin) offer functionality (though suggested more once).

using standard ngsi operations (updatecontext , querycontext), hard implement in wilma (i think) , require modify orion's plugins in steelskin. piece missing have support fine grained security (in steelskin case) add entity information frn used security.

but if restrict convenience operations (that reflect ids , attributes in url), use security on rest resources restrict resources based on entity features (but imply work xacml , so). in case, both pep proxies used.

edit: here can find complete set of convenience operations, can find information can added url creation of security rules.
