#### Row-Level Security (RLS)

# Meaning/Definition

Row-Level Security (RLS) is a database feature that controls access to
specific rows in a table based on the attributes of the user making the
query. It allows fine-grained access control, ensuring that users can
only view or manipulate data they are authorized to access.

RLS is commonly used in databases to enforce security policies
dynamically. Instead of creating multiple tables or views for different
users or roles, RLS applies rules or filters at the row level to
restrict access. This is achieved by associating security policies with
the table, which are evaluated for each query.

For example, in a multi-tenant application, RLS can ensure that users
only access the rows corresponding to their organization or tenant.
Similarly, in an employee database, RLS can restrict employees to only
view their own records.
