“Zero trust principles” increase the burden on IT teams to manage granular access.With this increase in complexity and overhead security problems follow: how long after an employee departure does it take for system access to be revoked? How much of this process is manual? When a person is promoted or changed roles, what new access should they gain automatically, what should they keep, and what must be revoked? For example: do new people managers automatically get special “manager” powers? These problems are universal, and there’s no single tool that solves them. This talk walks through a two year case study of building employee AAA as a regulated company grows from one to several hundred employees: how we got started in the world of data driven access, what employee data we’ve sourced, how we’ve built automation with a mix of low-code and no-code approaches and where we’ve used capabilities native to our HRIS, identity provider, and other tools to automate onboarding and offboarding.
