During pen tests, we found that even when a user account was terminated on the SSO, the user would still be able to access LITE using browser cookies.
Other DIT services get around this by using introspection middleware. This middleware hits the introspection endpoint on the SSO service and caches the response for a small amount of time.
We are doing something very similar for LITE.
P.S. It's not introspection technically because we are not using the
/o/introspect
endpoint from the SSO service. In the case ofstaff-sso
, it is because this endpoint requires a different token. For the case ofdirectory-sso
, I haven't been able to find an endpoint for introspection.
