10 free access control and permission management for modern web-app

There are different types of access control approaches:

  • ABAC - Attribute based access control.
  • DAC - Discretionary access control.
  • GBAC - Graph based access control.
  • MAC - Mandatory access control.
  • OrBAC - Organization based access control.
  • ReBAC - Relationship based access control.
  • RBAC - Role based access control.
  • RLS - Row level security PostgreSQL security feature

Origins of permissions DAC/MAC/ACL: https://tailscale.com/blog/rbac-like-it-was-meant-to-be#getting-more-concrete-rbac-and-abac

We built own ABAC solution with Nodejs for current CRUD tables for restricting users and create a team of teams. But faced with a inability to manage access for other microservices so we are looking for a solution that will not trap us on a monolithic architecture. So we can develop our value proposition for end-user with different programming languages.

It's very handy to deploy an additional microservices and add custom action at frontend. But it required to split this resource for each user.

Current monolithic solution uses 4 tables to store each rule and gives a conviniet dropdowns, parsing table of picked resource and dropdowns to select required column of a resource table while creating an if statement.

Since monolith is started to decentralize own backend we are looking for permission contorol solution to limit reseources per each user.

Too bad that we wasted time for developing own ABAC solution that could not be refactored into separate standalone service that could play a gatekeeper role. So I made some research to find best practices and ended with a list of an access control management frameworks.

Requirements

  • Policy should be written as a code for easy cope, paste and deploy
  • Centralized allow/deny/transform service for any backend or message broker
  • Open-source and self hosted
  • ?

Waste a decent amount of time to conduct an initial research and still in a process. Any question or commentary would be very helpful, so I will update article or publish new with more details and closer comparison.

Maybe little too to the party, but I would also add OPAL to the list github.com/permitio/opal
