Row-level security

security

Also called: RLS

Plain-language definition

Plain-language definition

Database rules that control which individual records a user may access.

Why it matters

RLS provides defense in depth against cross-account data exposure when application filters are missing or wrong.

Technical detail

Row-level security adds policies to database queries so selected, inserted, updated, or deleted rows depend on the active database identity and policy expressions.

Examples

  • A user can select only glossary preferences whose user_id matches the authenticated database identity.
