### Security
PostgREST handles authentication (HTTP Basic over SSL) and delegates
authorization to the role information defined in the database. This
ensures there is a single declarative source of truth for security.
When dealing with the database the server assumes the identity of
the currently authenticated user, and for the duration of the
connection cannot do anything the user themselves couldn't.
Postgres 9.5 will soon support true [row-level
security](http://michael.otacoo.com/postgresql-2/postgres-9-5-feature-highlight-row-level-security/).
In the meantime what isn't yet implemented can be simulated with
triggers and security-barrier views. Because the possible queries
to the database are limited to certain templates using
[leakproof](http://blog.2ndquadrant.com/how-do-postgresql-security_barrier-views-work/)
functions, the trigger workaround does not compromise row-level
security.
For example security patterns see the [security
guide](https://github.com/begriffs/postgrest/wiki/Security-and-Permissions).
